mostre gatti norvegesi, esposizioni gatti, stress gabbie esposizioni, tratti morfologici, aspetto estetico, patologie gravi, occhi sporgenti, sofferenza animali When "beautiful" means "genetic abuse" GENETIC MALTRACTING The breed standard is that set of specific morphological and behavioral characteristics that a subject - be it a dog, a cat or any other animal - should have in order to be included in a particular breed. Therefore, the standard is a point of reference both for breeders, who should aim to create a good "subject" and always improve it, and for owners who wish to have a dog or cat that meets the "sacred canons" "of the breed object of their desire. However, when selection is pushed to the extreme to privilege some exclusively aesthetic characteristics without looking at functionality and resorting to extreme inbreeding, problems begin to arise and genetic maltreatment takes shape, a much more serious form of maltreatment than simple suffering inflicted on a single animal since, on the contrary, it affects a large number of subjects and can be perpetrated for many generations to come. WHAT FUELS GENETIC MALTRACTING? Obviously, the fault is not only of the breeders, of the judges and associations that push more and more towards extreme hypertypes in which the aesthetic qualities (and functional defects!) Are enhanced to the nth degree, but the responsibility is mostly to be attributed to the market demands and the desires of an increasingly demanding public that in doing so does not look without realizing it to animal welfare, but aims only at the satisfaction of a whim generated by the subliminal messages that arrive from society . History repeats itself and we have all had the opportunity to witness, over time, the boom of this or that breed, perhaps in conjunction with the release of a successful film or, more recently, due to the desire to own a dog or a cat like that of television stars or web influencers who hammer us daily with their images and videos on socials. Fickle, temporary and fleeting fashions with a huge round of money behind them, unfortunately at the expense of animals that, although aesthetically cute and "perfect", pay the price of our superficiality having to live with physical problems that they compromise their quality of life or even their survival. Already in the 60s of the last century , a certain awareness of the importance of the "healthy" over the "beautiful" began to grow within the veterinary world and something, at a European level, is starting to move, albeit slowly and with difficulty. Even in our country something is starting to take shape in this sense, such as the establishment of the Cbv (Bioethical Committee for Veterinary Medicine), in 2018, or the birth of associations such as Asetra (Association of ethological studies and protection of the relationship with animals) . Giovanni Cubeddu, former Professor of Forensic Medicine at the University of Sassari and president of Melefovet (study group of Forensic and Veterinary Forensic Medicine of the Italian Association of Small Animal Veterinarians), and Ferdinando Meregaglia, freelance from Turin and secretary of Melefovet, explained the legal implications of genetic maltreatment, an aspect that is too often overlooked, but which can also have important implications for the veterinarian. The need to satisfy market needs deriving from the rapid request for aesthetically pleasing subjects and respondents to the fashion of the moment inevitably involves the use of a pushed inbreeding, using a few breeding subjects that bring with them both the desired morphological characteristics and even serious problems, an issue that the WSAVA had raised as early as the 1960s.

allevamento gatti norvegesi a Parma, il significato del nostro nome, intervista sul nostro allevamento, video sul gatto norvegese, allevare il gatto norvegese "Disir Nornir" Amateur breeding, which deals with the protection and safeguard of the Norwegian forest breed Protecting the Norwegian cat means to me, safeguarding this NATURAL breed (read the origins of the breed) through the study and comparison with other breeders, trying to preserve those bloodlines that are being lost in favor of others, used simply for aesthetic purposes. How did I become a "Guardian" of the Natural Race Norwegian Forest Cat "? Sometimes I wonder too ... To tell the truth, I never chose it ... it has been a long journey .. made above all of love for these cats, creatures so perfect, loving, joyful, who fill your life with unconditional affection. I've always been an animal lover, since childhood, but my adventure with cats Norwegian forest starts in 2006; I saw my first Norwegian cat on the internet, maybe how is happening to you in this moment ... it was a beautiful white cat with magic eyes, a magnetic gaze, sweet but so full of pride ... This cat that remained so impressed on me his name was Noel Maelstrom. After some searching, to find a Norwegian in Italy, another photo kidnapped mine heart ..... it was him! Cagliostro Vani's Ark, what would be later became my first Norwegian Forest Cat ... What a thrill it was to go and get it !! I remember like it was yesterday, the walk in the center of Arezzo, with my beloved treasure in the carrier ... and the return trip with Cagliostro who was all composed and sat on the back seat with his paws crossed .... he was a real Lord! and he would have kept this beautiful pride of his forever ... until his last moments of life, where with that paw of his, slightly protruding his nails ... he squeezed my hand for the last time ... Day after day my passion has grown and the desire for knowledge has pushed me to deepen their history ... and so without realizing it and driven by the passion towards their history and their so proud character, _cc781905-5cde-3194-bb3b -136bad5cf58d_ I was already in Milan to pick up Genny ... the future bride of Cagliostro .... I had become a "Norwegian Guardian" without realizing it ".... and so over time new friends arrived, such as Vamyr, Crystal, Maya, Isak, Brisingamen, Coral, Castella, Riddick, Brilliant, Agra, Catelyn, Marvel, Kamiko, Erza ..... some of them lived only part of the their life with me .... others are gone ... Genny is 15 years old and lives with me while his children Willy and Charlie _cc781905- 5cde-3194-bb3b-136bad5cf58d_ have recently left me ... It is not easy to explain for me who am not a writer, what a wonderful experience it is to be able to live with the Norwegian Cats ... treat them, see them born, grow .... but also being there in the moment of illness and death. .. all this becomes inevitably un personal growth path and despite the suffering to which it exposes me to raise, I am really grateful to these special beings, for everything they teach me every day , where their proximity, so clear and clean, is capable of healing your heart .. even from the most deep wounds. THE NAME "DISIR NORNIR" I have always been fascinated by mythology, since I was a child, but only thanks to the Norwegian cats, that I got to know Norse mythology. The Disir are a large group of female spirits who preside over Asgard, they determine the fate of all humans and gods. The three most important disir are the Nornir Urðr, Verðandi, and Skuld, whose names translate to "What is success "," What is happening "and" What will come " These three Nornir are hidden under Yddrasil, the World Tree, which has its roots in the water of the well of Urd and to prevent its roots from rotting the disir nornir scatter sand all around. As they sit under the world tree, Urðr, Verðandi, and Skuld weave the threads of man's destiny. Alongside these three Nornir there are many other Disir that come when a person is born in order to determine his fate, they are both benevolent and malevolent. Recent research has discussed the relationship between the Norns and the Valkyries, women who visited infants in pre-Christian Norse societies. The Disir Nornir remind me that the only constant in the universe is "Change" and with that in mind ... I imagine a large loom, the warp threads on the loom as our biological, spiritual, cultural heritage .... I imagine Urðr , Verðandi, and Skuld who weave the weft with the threads of our choices, which we have given them, the conscious and unconscious choices of all beings become the weft threads which are then woven together with the thread of inheritance and joining forming the magically mysterious fabric of the Multiverse. http://it.wikipedia.org/wiki/Multiverso

il pasce crudo o cotto nell alimentazione del gatto Fish in the cat's diet THE FISH IN THE BARF Fish offers the cat an important supply of Omega3, essential fatty acids. In fish, Omega3s are in the form of EPA and DHA, which are immediately bioavailable for the body It is advisable to feed fish in a percentage equal to 5% of the ration. With fish not containing thiaminase, it can reach 10% (more on this later). The fish can be fed whole, with bones, head, skin and viscera. It is absolutely essential to freeze before administration, in order to kill the parasite Anisakis (a nematode. In short, a worm!) Possibly present. It is not uncommon for fish to have this parasite, so freeze! _Cc781905-5cde-3194-bb3b-136bad5cf58d_ It is necessary to freeze for at least 96 hours. For fish purchased already frozen (for example the classic cod fillets) obviously it is considered that the procedure has already been extensively carried out! What does 5% mean in practice? It means 5% of the diet, whether calculated daily, weekly, monthly or otherwise. Practical example: A cat (about 6 kg) that eats 160 grams of total food per day, weekly this will eat 1120 grams of food (160 x 7). 5% of 1120 is 56. So this cat will eat 56 grams of fish per week. They may also be offered 110 gr of fish every 2 weeks for example. Of course we are not goldsmiths and the percentages are general indications. The important thing is to understand that you shouldn't go too far. Surely we must not exceed 10% of the total. Thiaminase Thiaminase is an enzyme that breaks down thiamine. Thiamine is vitamin B1. Thiaminase essentially inactivates vitamin B1. Therefore, the administration of foods containing thiaminase can lead to a deficiency of vitamin B1, if the recommended quantity is exceeded. Many freshwater and saltwater fish contain thiaminase, however not all. However, it is not easy to draw up a detailed list, since there are hundreds and hundreds of fish species in existence… and not all of us are experts in fish and the fish also change in common name from area to area. Here are some lists found: 1) Taken from "Mink breeding and diseases" published by the Foundation for zooprophylactic and zootechnical initiatives Fish containing thiamiasis: - Anchovies -Agueglie - Bleak -Anchovies - Alose -Herring -Barbi -European bass -Carps and Cyprinids -Cavedani -Coregoni -Lasche -Murene -Pagels -Persico trout -Catfish - White freshwater fish -Blue saltwater fish (rafts, sardines, mullets) -Stingray -Rombi -Red rudds -Scorpionfish - Mackerel 2) Taken from Thiaminase and its role in predatory pet fish (and other piscivores) nutrition http://www.wetwebmedia.com/ca/volume_6/volume_6_1/thiaminase.htm Fishes NOT containing tiaminasi (I report some of them. Others seem hardly present in Italy, such as North American sunfish for example !!): - Zander (Sander lucioperca) - Lake char (Salvelinus namaycush) - Rainbow trout (Oncorhynchus mykiss) Pike (Esox lucius) - Atlantic salmon (Salmo salar) --Silver salmon (Oncorhynchus kisutch) - Salmon trout (Salmo trutta) -Anguilla (Anguilla anguilla) -Platess (Pleuronectes platessa) - Cod (Gadus morhua) -Ricciola (Seriola dumerilii) -Spinarolo (Squalus acanthias)

leggende gatti norvegesi delle foreste The True * Origin of the Norwegian Forest Cat Written by Laura Achenza Traveler, whoever you are, you have come here to hear our story, and I ask the wind to let me tell ... *** At the beginning of time Odin, the Exalted, the father of all, created the whole universe and divided it into nine worlds so that every creature would find its place in it; in fact, their forms were many: giants of the mountains and Thursi of the frost, dwarves incomparable master craftsmen, dark elves blacker than pitch and elves of light more beautiful than the sun; Man was entrusted with Midgard, the middle earth, while the luminous gods, the ASI, lived in the stronghold of Asgard and there, from their magnificent thrones, still today observe and rule all the worlds…. Two crows are faithful companions of Odin who every day, at dawn, fly into the worlds and in the evening, at sunset, return, bringing back to their Lord everything that happens there. One day they reported to Odin that the Men of the Northlands were sad and lonely in the long winter night, in which darkness and cold reign supreme. All the ASI were then summoned to the council and each of them proposed to give men their own prodigy: Odin his horse Sleipnir who knows no fatigue and rides in the air, on land and on water; Thor his precious hammer to break the ice; Sif its long and luminous hair to dispel the darkness; Freyr his magical vessel, which always has favorable winds as soon as the sail is raised, and .... Freyja offered her cats .... The ASI Assembly established that, although all of them were prodigious gifts, the one that could truly warm both the body and the heart of the northerners were ... the cats of Freyja. _cc781905-5cde-3194-bb3b-136bad5cf58d _ *** Freyja will therefore have to part with the beloved company of her cats, but she, the goddess of love, knows that there is no better way to spread it around the world! He then decides, for the greater comfort of men and his own cats, to give them an additional magical banner: the sound of Love and Peace that will resound, in Midgard, every time a cat decides to purr .... and Freyja, every time, will be there to listen to him ... In return, however, he asks that his cats spread to every corner of the world, so that everyone can enjoy their magical presence. Therefore the ASI decide that Freyr's vessel will also be given as a gift so that the men of the North can sail everywhere and bring, in honor of the generous gods, Freyja's cats throughout Midgard . _cc781905-5cde-3194-bb3b-136bad5cf58d _ *** At the winter solstice, in the darkest night of the year, the vessel was laid down in a long fjord sheltered from the winds, which will therefore take the name of Sognefjord, the fjord of the dream, and Freyja accompanied her cats to the edge of the forest which stood near a village on a clearing; from that day, his cats belonged to the Norwegian forests and the world of men. Men honored the ancient pact with the Gods, and for centuries they carried the mighty creatures on their ships to every known or hitherto unknown land ... Other Men came and, renewing the covenant, they wanted to give recognition to the race which they called, in memory of their first home on earth, Cats of the Norwegian forests. In their homage they still bear these names proudly today: Vikjngs, Disir Nornir, Freya's Chariot, Of the Ancient Runes, Yggdrassil, Aesir, Lifthasir, Drakkar, ASI e Vanir, Asgard, Vanaheim, Niflheim, Alfheim, Svartalfheim, Midgotheim, Midgardheim Odino, Thorr, Freyja, Bestla, Vidharr, Verdandi, Vali, Var. _cc781905-5cde-3194-bb3b-136bad5cf58d _ *** Now my story has come to an end, but I want to reveal to you one last arcane secret: when your Norwegian cat stops enraptured, and his gaze seems to be playing with the air, know that he is in front of Freyja and for a moment, once again, together, they wander through the nine worlds… ..and you too, if your bond with him is intense, you will be able to see them in the distance. Therefore, remember to love and honor Freyja's gift forever ... Note I drew inspiration from historical texts and literary sources of Norse mythology, but I would like to clarify that the story is pure fantasy, and wants to celebrate and cloak these cats that I love immensely with noble origins. It is therefore a tribute to them and to all fans of this splendid breed.

perchè i gatti cadono dai balconi? i Veterinari hanno scoperto che ... The cat volante For all those who are convinced that cats do not fall and that if they fall they are not hurt I invite everyone to read these lines, written by a veterinarian. Because it is better to think about it first than to despair later. “Flying cat is, in veterinary jargon, the cat that falls from a high floor: a typical spring patient because, in the first heat, people open the windows and cats fall from the eaves. Yes, I know that I am undermining a fundamental pillar of your cat beliefs, but unfortunately it is: it is not true that cats do not fall and it is not true that if they fall they do not get hurt! In several years of first aid I have seen too many incredulous owners forced to change their minds in tears on an inert body: "But he always started sunbathing on the windowsill ..." NEVER trust the common sense of a cat! It is also true that there are many cats who walk on the railings all their life like tightrope walkers without ever falling: so why do some people fall? Given that the owner hardly ever sees his cat the moment he is falling, and therefore it is impossible to know what happened, I noticed one thing: for a while, I visited the litters of new strays on a glass counter. like those of the haberdashery: the kittens, even solidly resting on the surface, could see the void beneath them. Well, some were clearly terrified of this feeling and backed away to get to safety, others didn't care. Could it be that some cats do not have a sense of emptiness and that this predisposes them to fall? It is only a hypothesis, but I point it out. It is however possible to trace an identikit of the flying cat, on the basis of clinical cases: they are generally young cats, born the year before and therefore are found for the first season to be able to jump on windowsills and railings when the windows they are open, or cats of any age who have moved to a high floor during the winter, or those who have joint or vision problems. The few owners who are present when the cat falls report distractions (the butterfly that passes under its nose just as it is jumping) or errors of assessment (the cat that jumps on the doormat leaning to dry astride the railing) ... The cat falls mostly in the evening or at night, either because it is more active in these hours, or because the owners come back and open the windows only in the evening, and is found at dinner time or, poor thing, the morning after all. breakfast time. The season runs from about April to June, from the first heat to when ... the cats run out, but they are seen throughout the summer, including repeat offenders! Yes, because moreover these mysterious animals do not learn from their mistakes, and I have seen at least two return twice in a fortnight ... But here it also gets a bit of the owner's head, isn't it? What injuries can the flying cat get? The injuries of falls from a height range from an unharmed cat to a dead cat, passing through a whole series of accidents grouped under the English definition "high rise syndrome": fractures of the palate, limbs, back, diaphragmatic ruptures, bladder , lung, etc. A thrilling anthology that I hope you never have to experience. Extensive literature has been spent trying to correlate height and injury, but I have seen cats fall off the same floors and some live and others die: in my experience it is more important what they encounter on the descent, which can alter the flight attitude. and the type of soil they find on the ground. If your cat unfortunately falls from above, always take him to a veterinarian immediately, even if he seems unharmed: certain injuries may not be visible immediately, but only when it is too late ... If, on the other hand, you see him "unsafe" on a ledge, avoid shouting and calling him alarmed, frightening him and pushing him into rash movements: it is better to make a tempting movement of bowls and treats come from inside the house. But a lot can be done in terms of prevention: like some of my clients, without getting to move to the ground floor to prevent cats from falling. I always recommend equipping all windows with mosquito nets, while for balconies and terraces the nylon fishing net is fine, anchored and stretched up to at least two and a half meters high, preferably equipped with a "roof" also with a net . I lived on the fifth floor for several years and I assure you it works. Does it seem excessive to "armor" the balconies for the cat? You see ... with this solution I have always slept soundly (and without insects!). Trust me, it is better to think about it first than to despair later ”.

Musica rilassante per i gatti. Questa è musica composta appositamente per i gatti ed è stata verificata per essere efficace da due studi universitari separati... RELAXING MUSIC FOR OUR CATS by MusicforCats Album One This is music composed specifically for cats and has been verified to be effective by two separate university studies. At first glance, the idea of cat music makes reasonable people think "whaaa?", But this is true. This song is taken from the first full album of species-specific music that was created using a process that has been tested and verified by independent scientists (University of Wisconsin-Madison and Louisiana State University School of Veterinary Medicine). The release of the album further promotes our goal of providing enrichment for animals based on the unique perception, communication and development of each species. This music was designed from the ground up to appeal to cat sensitivity, just like human music is designed to appeal to humans. If we want to connect with our cats through sound in a meaningful way, shouldn't we try to hear the world as they hear it? Brain development and cat vocalizations are the foundation of this music, making it a new and unique form of communication and environmental enrichment that can improve the relationship between you and your feline companion. For more information on the background of this music and the results of independent studies, visit our website: musicforcats.com

colorazione dei gatti norvegesi, silver, smoke, shaded, causati da un gene che scolora il pelo partendo dalla base, colorandolo dei toni dell argento. ( esistono 2 teorie) SILVER AND SMOKE "Il gene that makes the Norwegians shine" In some Norwegian cats the brindle design contrasts, instead of on the usual yellowish background on a background white / bright silver; in others, when they walk, the hair opening reveals the sparkle of an icy fog. These cats are always a sight e depending on the design of the coat called_bsc7905-bbc3b3-81d81-3194b9905-bbc3cc3-3194bd81-136b905-3194bd81-136bcc3 -136bad5cf58d_ (smoke), _ cc781905-5cde-3194-bb3b-136bad5cf58d_ Silver (silver), _ cc781905-5cde-3194-bb3b-136bad5cf58d7_Shaded5-136bad5cf58d_Shaded5-136bad5cf58d_Shaded5 Whatever name they are given, they all have one feature in common: the presence of a gene that makes the pigment at the base of the hair disappear completely, the area closest to the skin of cats where the hair is already normally less densely colored due to the effect of body heat on the melanin granules. The gene in question is dominant, and is indicated with the letter "I" capital Smoke, Silver and Shaded obviously can exist on all colors of Norwegians. Below you will see a large gallery of images. SMOKE: Cats are called "Smoke" in which the "I" gene, which discolours the hair at the base, is present on a "NOT TIGERED" cat The root of the hair (from 1/3 to half of the length) is silver white, while the rest is colored: the stationary cat seems to be solid in color, only when it moves can you see the contrast at the base of the hair. Often one can notice a gray shade of the black fur which forms a rich silver colored ruff. Smoke puppies often have a brindle pattern (phantom brindle), which usually disappears within the first year of life. SILVER Cats are called Silver in which the "I" gene that discolors the hair at the base is present on a "TIGRATO" cat The tab design which often includes darker and lighter bands, usually yellowish, in the presence of the silver gene, _cc781905-5cde-3194-bbcfb-136d of a very bright ice white, on which the design will stand out in a particular way. Often on puppies, up to the age of 5/6 weeks is not easily recognizable. Photo gallery of SMOKE cats with and without white Photo gallery of SILVER cats with and without white Hints of Genetics Feline genetics: a combinatorial approach Massimo Picardello University of Rome “Tor Vergata” Department of Mathematics 00133 Rome, Ital y The silver colors (smoke, silver). We now turn to the silver-colored varieties: smoke, silver tabby, shaded silver and chinchilla (and their pheomelanistic equivalents, sometimes called cameo). In these varieties, the base of the hair is depigmented, silver white, without traces of reddish tones. In some silver tabbies, however, the color reaches the root of the hair in the brindle areas. Silver tabbies are brindle cats whose agouti areas are a livid silver hue, with high contrast to brindle. Chinchillas have no traces of branding (in the case of an ideal specimen), and only the tips of the hair are colored (tipping). In shaded, the color on the tips of the hair covers about one third of the length (often less). In the smoke, the silver part is between a third and the initial half of the hair, the rest is colored. The one-gene theory In the past, a single main gene, , was considered responsible for silver colors. indicated with I (inhibitor), responsible for the braking action on the production of pigment and also for the elimination of the reddish shades typical of eumelanistic colors, especially in the agouti areas of brown tabbies. The mechanism by which a single gene can produce such different color varieties is as follows. Smokes are non-agouti cats, and the I gene lightens and bruises the base of the coat, giving it a pure silver color, evenly over the whole body. The braking action of the pigmentation produced by this gene can be limited to about a third of the hair, or be greater, reaching the middle of the hair or slightly beyond. All other silver varieties are agouti. Chinchillas and shaded are agouti with a ticked pattern. (Important warning: Chinchilla or shaded silver puppies often display a mackerel or classic [= blotched] phantom pattern, which disappears as they grow. This does not mean that these puppies are not genetically ticked. Ghost bands are common in ticked puppies: ad for example, they are sometimes seen in the Abyssinians. At most, the presence of phantom stripes may be an indication that the cub is heterozygous for the ticked pattern, but this is not necessarily true). Gene I lightens the base of the hair, but without its effect the hair would not have been all pigmented: there would have been various agouti bands, lighter. The action of I brightens the brown tones of these bands and transforms them into silver as well. Since the lightening due to the inhibition at the base combines with the further silvering of the agouti bands above the cut level of the inhibitory action, the percentage of silver hair extends, and reaches about two thirds in the case that the gene I operate in a mild way (shaded silver), and on all the hair except the tip (the last band of color of the ticked hair) in case the action of I is accentuated (chinchilla). That the chinchilla and shaded silver of eumelanistic colors are agouti is also clear from the fact that the skin of their nose is brick red (or deep pink) with the typical external border of brindle. Finally, the silver tabbies are brindle with a classic (blotched) or mackerel / spotted pattern. it is clear that the action of gene I is much more visible on the agouti areas than on the markings of the brindle, and this gives rise to the brindle design with very high contrast. But just by examining the silver tabbies we see that the genetic explanation of silver colors cannot be based on a single gene. In fact, if this were the case, the brindle markings should be lightened at the base, as in the smoke. But if on the one hand we see silver tabbies of this type, on the other hand we see many others in which the color reaches the root in the brindle areas. Geneticist Roy Robinson, in his well-known book Genetics for Cat Breeders (Cambridge, 1972, 2nd edition), suggests that on brindle areas the action of color filling overpowers silver lightening. But this seems strange, given that on smoke, where the same action occurs on the whole body, the opposite occurs. In any case, it would not be possible to explain why in some silver tabbies there is basic lightening in the brindle areas and in others not. The two-gene theory The most modern theories - see the articles by J. Jerome, TICA Trend vol. 13 n. 6 (Dec. 1992 / Jan. 1993) pg. 14 and TICA Yearbook 12 (1991), pg. 218- assert that two distinct genes act on silver, one responsible for the inhibition of the pigmentation at the base of the hair, the other for the elimination of reddish tones (bleaching, bleaching). We will call this second gene the "silver gene" (Sv). The inhibition gene, on the other hand, we will indicate with I, warning the reader on the fact that some recent texts denote with Sh the mild form of the inhibition gene, responsible for the shaded mantle, and with Ch the intense form, responsible for the chinchilla mantle . But there is insufficient evidence that the difference between the two effects is due to two alleles of the inhibiting gene rather than the action of a group of supporting polygens, and indeed the transition from shaded to chinchilla mantle is quite gradual. than net. Therefore we will not refer here to the alleles Sh and Ch, confident that the reader can now easily adapt the conclusions to the context of articles or books that instead refer to them. Therefore, in these notes we do not distinguish genotypically shaded silvers and chinchilla, attributing the difference to secondary polygens. At this point, the correspondence between the color varieties seen above and their genotypes is clear: Smoke: aa I- Sv - Shaded silver and chinchilla: A- TaTa I- Sv - Silver tabby mackerel / spotted: A- TT I- Sv - if the root of the hair in the brindle areas is silver (silver tabby shell or shaded, depending on whether the silvering is accentuated or reduced); branding is not silver. Silver tabby classic (blotched): A- TT ii Sv - if the hair root in the areas of A- tbtb I- Sv - if the root of the hair in the brindle areas is silver (silver tabby shell or shaded, depending on whether the silvering is accentuated or reduced); branding is not silver. A- tbtb ii Sv - if the hair root in the areas of We have indicated the ticked design gene in shaded and chinchilla as homozygous because the dominance of the design genes is only partial. For example, the TaT combination produces a hybrid design, with diffuse ticking partially superimposed on a mackerel design (mainly on the legs and tail, but often a little also on the flanks). If this is the genotype, the uniformity of the tipping is lost. Of course, cats with these characteristics would still be registered as shaded or chinchilla, but their color would be less consistent with the standard. It should be noted that an ideal silver tabby does not need the action of the inhibition gene I to achieve a perfect contrast between base areas and stripes. In fact, the silver Sv gene lightens and transforms the agouti bands of the hair in the base areas into a pure silver color, which therefore results silvery and livid. Furthermore, the absence of the shading gene I causes the brindle areas to be intensely colored up to the root, increasing the contrast, especially on black silver tabbies, where the elimination of reddish tones makes the black color more intense. is alive. Other color varieties predicted by the two-gene theory; the golden If we substituted genotype I- with genotype ii in shaded and chinchilla, we would obtain A- TaTa ii Sv-. Phenotypically, these cats should be silver ticked tabby in the variant ii, not shaded, that is, with a black band at the beginning of the hair, in contact with the skin. However, it does not appear that these cats were ever produced (see below for further comments). Similarly, if you do the same in the smoke, you get aa ii Sv-, which phenotypically corresponds to solid cats but without traces of rufousing, that is, reddish shades of the hair in eumelanistic colors, or warm tones in pheomelanistic colors. These cats can be obtained by crossing silvers heterozygous for the I gene. If cats of this type are then further crossed with each other, kittens of genotype ii sv sv can be born. From a line of smokes (non-agouti), normal solids are obtained in this case; from a line of shadeds or chinchillas, let's say homozygous agouti AA TaTa, normal ticked tabbies are obtained (like the Abyssinians; however all the shaded and chinchillas are selected against rufousing, that is in favor of polygens of redness of the hair that favor the more bruised, and therefore cannot be expected to obtain, from shaded parents or heterozygous chinchilla Ii Sv sv, ticked tabby puppies with warm reddish tones of the Abyssinians). But if instead shaded or chinchilla heterozygous for Sv and the inhibitor gene I are crossed, it will be possible to obtain puppies with the I-sv sv genotype. These puppies will be ticked tabby with the base of the hair lighter, but without the bruises produced by the sv gene (but still with not too bright reddish tones, due to the polygenic selection against rufousing). The base shade will be gold instead of red. This variety of color, in the eumelanistic versions, is called shaded golden. The corresponding pheomelanistic varieties are too close in phenotype to red (or cream) ticked tabbies to be classified as a variety in their own right. Similarly, golden tabbies can be obtained by crossing silver tabbies heterozygous for the Sv gene. Here are the genotypes of golden, compared to those of brown tabbies: Shaded golden and chinchilla golden (golden shell): A- TaTa I- sv sv Golden tabby mackerel / spotted: A- TT I- sv sv (note that the root of the hair in the brindle areas is depigmented: golden tabby shell or shaded, depending on whether the depigmentation is accentuated or reduced); Brown mackerel / spotted tabby: A- TT ii sv sv (the root of the hair in the brindle areas is not depigmented.); Golden classic (blotched) tabby: A-tbtb I-sv sv (note that the root of the hair in the brindle areas is depigmented: golden tabby shell or shaded, depending on whether the depigmentation is accentuated or reduced); Brown classic (blotched) tabby: A- tbtb ii sv sv (the root of the hair in the brindle areas is not depigmented.). Unverified predictions of the two-gene theory The reader must be warned that this genetic pattern is not entirely satisfactory. In fact, from it we deduce the existence of phenotypes not observed so far. For example, the aa I-sv sv genotype should correspond to a "golden smoke", ie a smoke with a base color of gold rather than silver. But to date, a cat with the color of golden but non-agouti has not been produced. Therefore, it may be assumed that the sv gene is inactivated on non-agouti cats. In this case, the genotypic difference between solid eumelanistic cats with or without traces of rufousing would be due only to the action of polygens. As already observed, also for the silvers (not golden) there is a dubious phenotype: the one corresponding to the genotype A- TaTa ii Sv-. It should be silver cats but not shaded, that is without depigmentation at the base, and with ticked design. As already observed, under the action of gene I the agouti bands become silver, and for example it is possible to see the effect of multiple alternating silver and black bands in the agouti areas of the black silver tabbies mackerel or blotched not depigmented at the base. But in case the design is ticked, we should have a phenotype with all the fur with alternating silver and black bands, and black at the base (in case the base color is black, of course). It is not known that cats of this type were ever produced. It can perhaps be assumed that the Sv gene is active only if gene I is active, and in fact it modifies and reinforces its action. The two additional assumptions we have made in this section in order to "rescue" the two-gene theory are equivalent to assuming that the entire Sv / sv allelic series is inactive except if gene I is present. No research has been done yet. experimental enough to confirm this conjecture. The theory of the golden factor If this last conjecture is true, in fact the two-gene theory becomes equivalent to another genetic model, which was introduced before the theory based on two independent genes. In this previous model, golden were explained by introducing, however, an additional gene g, whose epistatic action causes golden color instead of silver at the base of the silver coat (as is done to explain the Maltese dilution starting from gene B, with the addition of an epistatic gene d). The dominant allele G has no effect (does not cause a golden color at the base). Finally, it should be noted that the Sv gene causes a lack of rufousing in eumelanistic colors, but much less in pheomelanistic ones. There are red smokes and red shaded silvers whose tipping is quite hot red (especially in smokes). The golden theory = brown ticked tabby Another genetic scheme that was considered consisted in identifying the golden ones with simple cats of ticked tabby color (whose design is ticked all over, without any stripe of brindle; in TICA it is called "agouti tabby"). In fact, because the color of the coat is sensitive to temperature, it is almost always true that ticked tabby cats have a lighter coat base (open the coat of an Abyssinian!), And often the golden and ticked tabby phenotypes are difficult. to distinguish. Faced with the difficulties indicated above, deriving from the two-gene model of silver colors, this simple conjecture that golden is nothing other than ticked tabby is suggestive. In fact, the only phenotypic trait that this theory does not explain is the fact that some ticked tabbies are not very clear at the base while others (the golden ones) are very clear, but perhaps the difference could be attributed to the action of a group. of modifier polygens. Despite the difficulties, however, we will continue the discussion based on the two-gene theory, because it gives the most satisfactory explanation for the existence of two types of silver tabbies: those with black tabby areas up to the root and those with depigmented tabby areas. at the base of the hair. However, we observe that, as regards the most important phenotypic traits, this theory that identifies golden with ticked tabbies provides the same percentages of probability for crosses as the two-gene theory. The Broadband Gene Theory Finally, alternative theories have recently been considered in which two genes appear, but with different effects from what has been said above (contributions by H. Lorrimer on the Internet Fancier's List, March-April 1995). In fact, one gene is still the silvering (rufousing elimination) silver gene, but the other would be a gene that causes broadening of the light bands in agouti hair, called wide-band (Wb). However, it should be noted that, due to the large degree of variability in the length of the tipping, it would be more appropriate to speak of a group of broadband branding polygens. In this theory, the problem related to the fact that golden are only agouti (golden smokes are not observed) is obviously solved, but on the other hand the smokes are not explained, which are not only silver (i.e. without rufousing), but also lightened at the base. As these are non-agouti cats, this aspect of their phenotype cannot be due to genes that widen the clear agouti bands. On the other hand, a variant of this theory can be used to justify a theory advanced in some books: that chinchillas and shaded silver are not necessarily of ticked design. The ticked design, together with the silver inhibiting action, ensures that the color is limited to the tip of the hair (tipping). For g | the other designs this would not be the case, and furthermore the length of the tipping would be far from uniform. But if the agouti bands were dilated by a group of wide-band polygens, and then silvered by the silver gene, then the tipping would be confined to the tip of the hair, and there would be an acceptable degree of uniformity. The theory [golden = brown ticked tabby + broadband polygens]: finally an exhaustive genetic model for smoke, silver and golden! Let us return to the theory that identifies the shaded golden and ticked tabby color varieties. This is 19 the most satisfactory theory we have encountered, except for the crucial circumstance which does not explain the partial depigmentation at the base of the hair, a fundamental characteristic of the shaded golden phenotype. On the other hand, there are many cats registered as golden and with varying degrees of depigmentation, some even with almost no depigmentation ... Therefore it must be assumed that shaded golden depigmentation is not the effect of a main gene with net action. (or depigmentation or full color), but the result of the gradual (and sometimes very reduced) action of a set of polygens. But there is already a candidate for this group of polygens: the broadband modifiers introduced in the previous section. Then shaded golds would be nothing more than ticked tabby with broadband base brightening (aside from eye color, which we'll talk about later). If so, everything is fine: the golden must be tabby (no golden smokes!) And partially depigmented at the base (but the amount of depigmentation varies from one specimen to another depending on how much the effects of the individual modifier genes are added together. broadband). Naturally, in this theory the ideal shaded golden results result from crosses of shaded silver heterozygous for the silver and homozygous for the ticked pattern. What if the shaded silver parents are heterozygous also for the ticked drawing? For example, parents might carry the mackerel factor. In this case, if instead of being silver they were brown tabby (no silver), the parents would have brindle lines on the legs, chest and tail, due to the partial dominance of the ticked allele on the mackerel. But as they are shaded ilver, the branding lines will be there, but they will be faint. And in fact, there are some shaded silvers with faint traces of branding (especially from puppies, before the agouti gene reaches maximum effect). However, their golden kittens are not silver, they are brown ticked tabby, and if they carry the mackerel allele the bruises will be clearly visible on the paws, a very undesirable feature in shaded golden, but frequent. To complete the picture, the broadband modifiers transform the other designs (spotted, mackerel and classic) into the corresponding golden varieties (golden spotted tabby, golden mackerel tabby and golden classic tabby respectively), in which the agouti areas are partially depigmented at the base and have warm apricot tones. Now we finally have a satisfying golden theory. However, in order to be compatible with the silver one, it is necessary to review and correct the latter. We can no longer hypothesize two genes for silver, one for depigmentation and the other for silvering. Instead we have to go back to the one-gene theory, an inhibitory gene that we will continue to call I and that simultaneously causes silvering and depigmentation, as in smokes, for example. It should be noted that the golden genotype is not due to gene I (indeed the golden ones are heterozygous ii): the depigmentation at the base of the golden hair is instead due to the elongation of the first agouti band due to the action of the broadband modifier genes. We do not introduce a distinct main gene that causes depigmentation, otherwise, as we have seen, the theory would predict the non-existent golden smokes (golden non agouti, depigmented at the base of the hair). On the other hand, it would seem at first glance that this loses the brilliant explanation that the two-gene theory gave regarding the fact that some silver tabbies are depigmented at the root of the hair in the brindle areas and others are not. But this genetic trait can be explained in some other way. The gradual level of depigmentation at the base of the hair in the brindle areas may be caused by modifier genes similar (or possibly identical) to broadband modifiers, whose action is limited to tabby cats. With a slight conceptual abuse we can imagine that these additional modifiers belong to the same group as the broadband polygens (in reality this is not the case, because the latter act on the agouti base areas while the former act on the brindle areas: but in reality they meet many golden in which broadband depigmentation also occurs on the areas of tabby marks ...). In summary, compared to the two-gene theory our new genetic model retains the inhibitor gene I (which is now considered responsible for both depigmentation and silvering, as in the one-gene theory), and replaces the second gene with a group of polygens. , which we will denote by Wb (for "wide-band"). What is particularly satisfying is the fact that the gradual action of broadband modifiers can explain the difference between the shaded silver and chinchilla phenotypes. Unfortunately, however, we are assuming that these are polygens, which therefore are not subject to the simple and direct rules of Mendelian genetics for the main genes. In order to analyze the mathematics of this new model it is necessary to resort to statistics, the results of which are too fine to be clearly distinguished in the phenotypes. Therefore it is not easy to present the results by means of cross tables. Silver and golden It should be noted that the deepening of the single gene theory presented in the previous section, as well as the variant introduced previously, excludes the possibility of cats at the same time silver and golden: the silver phenotype is a consequence of the inhibitory gene, which the golden they do not have. Both shaded silver and golden have broadband type color suppression or lightening genes, or polygenic modifiers of the same type. In the latest version of the theory that we presented immediately above, the golden pattern is caused by the suppression action of this type of genes superimposed on hairs with already banded coloring due to the Agouti gene: thus, if the tabby design is the ticked, you get the perfect golden pattern, uniform throughout, but if the design is mackerel, spotted or (even worse) blotched, then more or less large areas of tabby marks become evident with full color, not very lightened, only orange in color in the band at the base. These patterns could be classified as golden tabby (mackerel, spotted or blotched, respectively). Since in such cases the areas where the coat has a broad golden base are less broad, these phenotypes are more difficult to determine with certainty, particularly in kittens, especially if they are phantom patterns in young cats due to heterozygous tabby genotypes with a only ticked allele, and some origins books (for example that of TICA) do not recognize them. Finally, it should be noted that the action of broadband suppression genes creates long agouti bands of pheomelanistic color, which are difficult, if not impossible, to recognize on cats of already pheomelanistic base color. If the lightening band is not long this is easier, just like in the case of the tortie ticked tabby pattern. Eye color of shaded and golden: an example of persistence? In relation to the similarity between golden and ticked tabbies, it should be remembered that in ticked tabbies the color of the eyes is gold or copper (in the case of Persians) or also hazel or yellow or yellow-green or green (in the Abyssinians). In the shaded silver or chinchilla of eumelanistic colors the eye color is not gold or copper, but emerald or blue-green. Instead, in the shaded silver or chinchilla of pheomelanistic colors, the eye color is copper. With appropriate crossings and consequent selection, it has been possible to introduce the gold or copper color in the eumelanistic shaded silver: the corresponding standard, recognized by some feline associations but not all, is called black shaded (in England, pewter). So the difference between an eumelanistic golden and the corresponding ticked tabby, although it may be barely visible in the color of the hair, is still evident in the color of the eyes, emerald in the first but not in the second. In silver tabbies, on the other hand, the eyes are green or yellow-green or gold, with a preference for green. In the shaded and in the pheomelanistic silver tabbies the color of the eyes is copper, and in the corresponding tortoiseshell varieties it can be copper or emerald (shaded) or green (silver tabby), with preference for copper. The existence of black shaded with gold eyes reveals that the emerald color of the eyes is not caused by the silver gene. It is interesting to observe that, although the color of the eyes, emerald or copper, is largely determined by a main gene, it is not common to meet eumelanistic shaded silvers with copper eyes: the emerald color occurs more frequently. So, although the color of the eyes and the hair depend on different genes, somehow there is a persistent link between the shaded silver coat and the emerald color of the eyes. This link is perhaps due to the fact that the main genes that cause this eye coloring are located on the same chromosome as the genes that cause the shaded silver color of the coat, and therefore the genetic transmission of one and the other occurs together. A situation of this type, which is called persistence, modifies the probabilities of concomitant genetic transmission of the two genes, which are very different from what they would be for two independent genes. To break the persistence, in fact, it is necessary that in the close contact of the two homologous chromosomes during the pairing that precedes meiosis, a genetic recombination takes place, that is a molecular exchange between the two chromosomes. The action of the I and Sv genes is epistatic on that of the solid color, eumelanistic and pheomelanistic genes, but not on that of the white (W) and piebald spot (S) genes. Obviously, the W- B- A- TaTa I- Sv- genotype corresponds to a phenotype in which white masks the shaded silver color on the coat, but the eye color can be either blue (due to the depigmentation action that the gene W can exert on eye color) or emerald.

"Scopri tutto sull'allergia alla Fel d 1, la proteina della saliva del gatto responsabile delle reazioni allergiche. Approfondimenti, soluzioni naturali e il nostro innovativo progetto per ridurre ancor di più , l' allergene dei Gatti Norvegesi delle Foreste. The Cat Allergy Se stai cercando un gatto che non provochi allergie, un gatto anallergico o ipoallergenico, oppure prodotti per ridurre l’allergia al gatto, voglio prima dirti una cosa importante: "capisco perfettamente cosa stai vivendo" Il desiderio di condividere la vita con un gatto, quando c’è di mezzo un’allergia, può sembrare un sogno impossibile, ma nella maggior parte dei casi non è così. Da oltre 20 anni allevo con amore i miei gatti Norvegesi delle Foreste e ho accolto centinaia di persone allergiche; moltissime di loro pensavano di dover rinunciare per sempre a un compagno felino e invece, con le giuste informazioni e le corrette strategie, hanno scoperto che convivere con un gatto è possibile. Esistono gatti anallergici? La risposta sincera è: non esiste una razza totalmente anallergica. Quello che provoca l’allergia non è il pelo, ma una proteina chiamata Fel d1, prodotta principalmente dalla saliva e dalle ghiandole sebacee del gatto. Quando il gatto si lecca, la proteina si deposita sul mantello e poi si diffonde nell’ambiente. 👉 Alcuni gatti producono molto meno Fel d1 rispetto ad altri. 👉 La produzione di allergene è influenzata da fattori genetici e ormonali. 👉 I maschi interi producono più allergene rispetto ai gatti sterilizzati. Ecco perché si parla più correttamente di gatti a bassa produzione di Fel d1, non di gatti “anallergici”. Quali razze sono considerate ipoallergeniche? Studi condotti su diverse razze hanno evidenziato che in alcune linee genetiche si riscontrano livelli più bassi di Fel d1. Tra le razze più citate: Gatto Siberiano Gatto Norvegese delle Foreste Gatto Abissino Questo non significa che tutti gli esemplari siano adatti a ogni persona allergica. Ogni soggetto allergico reagisce in modo diverso. Per questo il test diretto in presenza è sempre il metodo più affidabile. Come funziona un test allergico in allevamento? Il modo più realistico per capire se puoi convivere con un gatto è semplice: trascorrere almeno un’ora in ambiente chiuso con i gatti adulti. Nel mio allevamento, questo momento è gratuito ed è pensato come un’esperienza serena, non come una prova di coraggio. La maggior parte delle reazioni a Fel d1 si manifesta entro 15–30 minuti. È importante: portare con sé eventuali farmaci (antistaminici, inalatori, colliri) evitare di assumere antistaminici prima della visita (previo parere medico) ripetere la prova in giorni diversi se possibile Questo approccio è molto più attendibile rispetto ai semplici test su campioni di pelo. Perché alcune persone allergiche tollerano certi gatti? L’allergia al gatto può coinvolgere diversi allergeni: Fel d1 (il principale responsabile) Fel d2 (albumina felina) Fel d4 (lipocalina) Alcune persone reagiscono solo a Fel d1, altre a più allergeni contemporaneamente. Chi è allergico a cavalli o conigli, ad esempio, può essere sensibile alle lipocaline. Ecco perché non esiste una risposta universale, ma esiste un percorso personalizzato. È possibile ridurre l’allergene del gatto? Sì. E questa è la parte più importante. Oggi sappiamo che la quantità di Fel d1 nell’ambiente può essere ridotta in modo significativo attraverso: ✔ Sterilizzazione Riduce la produzione ormonale e abbassa i livelli di allergene. ✔ Gestione dell’ambiente Lettiera pulita quotidianamente Sabbie a bassa polverosità e senza profumo Aspirapolvere con filtro HEPA Aerazione frequente degli ambienti ✔ Cura del mantello Passare un panno umido sul pelo Bagno periodico (se il gatto lo tollera) Utilizzo di prodotti specifici come Allerpet ✔ Alimentazione mirata Esistono oggi protocolli alimentari specifici in grado di ridurre dal 30% al 50% la produzione di Fel d1 nel gatto. Se stai cercando prodotti per ridurre l’allergia al gatto, oppure soluzioni naturali e nutrizionali per abbassare l’allergene, puoi contattarmi per ricevere informazioni aggiornate. Esiste un vaccino per l’allergia al gatto? L’immunoterapia specifica (comunemente chiamata “vaccino antiallergico”) è una terapia medica prescritta dall’allergologo, che può aiutare il sistema immunitario a tollerare l’allergene nel tempo. È sempre fondamentale confrontarsi con uno specialista prima di prendere decisioni. E ora.... Se sei arrivato fin qui, probabilmente ami profondamente i gatti. E forse ti sei sentito dire che “non puoi averne uno”. La verità è che ogni situazione è diversa. Con informazioni corrette, test fatti seriamente e strategie personalizzate, moltissime persone allergiche oggi vivono felicemente con il proprio gatto. Non sei solo. E non devi rinunciare al tuo sogno senza aver esplorato tutte le possibilità. 📌 Se vuoi ricevere aggiornamenti su: gatti a bassa produzione di allergene percorsi alimentari per ridurre Fel d1 test allergici in allevamento soluzioni pratiche per convivere con un gatto nonostante l’allergia... 👉👉👉 contattami direttamente.
