Canadian sphinx
Almost everyone who has dealt with sphinxes claims that the Canadian sphinx is the most loving breed ever created on Earth.
A special character is one of the sphinx's typical features, as is its naked hot body and unusual appearance. It seems that the sphinx has lost much of its cat behavior along with its coat. I am wonderful to all the representatives of the cat world, I like many breeds, in their own way beautiful and amazing, but I just want to emphasize that the Canadian sphinx is no longer a cat! Obviously, something is happening to the psyche of the animal under the influence of a mutation that is radically changing its appearance. Ask the owners of naked dogs, whether they're Mexican, Peruvian or Chinese, and they'll all say in one voice that their pets aren't exactly dogs anymore: they're very affectionate and completely devoid of aggression! However, they were not just dogs, but special human helpers with magical properties.
Mention of bald cats can be found back in antiquity. Nowadays, such reports have been published periodically for over 100 years. It is considered, that naked cats were still at Aztecs that seems quite probable, after all they had naked dogs!
As for cats, the last representatives of the ancient breed called Mexican Hairless were shown at cat shows in the USA at the beginning of our century. Until the early 30's the only couple survived, unfortunately, never left their offspring. According to the description, Mexican cats differed from modern sphinxes: they had an elongated body, long tail, wedge-shaped head with big ears, amber eyes and long mustache, which are almost completely devoid of sphinxes. In winter, short wool grew on the back and tail, which disappeared by summer. The genetics of that mutation remained unknown: whether the sign of hairlessness was transmitted by a recessive or dominant type. In the latter case, it is possible that the Mexican and our domestic hairless cats were genetically twins. In any case, both with their hairless mustaches are preserved, both breeds tend to dress in a "fur coat" by winter.
Individual cases of hairless kittens in litters of ordinary cats were observed all over the world. Until recently, however, no attempt has been made to create a new breed. The emergence of a hairless cat breed is associated with 1966, when in Ontario, Canada, among the kittens of a normal domestic cat was found a hairless kitten. The cat was crossed with his mother after a proper time and normal and hairless kittens appeared in the litter. As long as it was possible, it was taken with his daughters, granddaughters to preserve as many of the original genes as possible. The result was two kinds of sphinxes, slightly different in appearance. But soon the US and Canada stopped breeding sphinxes. In 1971, CFA withdrew the temporary status given to the breed before that. What was it about? Sphinx breeding failed for several reasons at once.
First, the breed was extremely small and there was no hope of stabilizing it using the animal felinologists available. Besides, the breeders didn't understand the genetics of the sphinxes. It was mistakenly thought that the sign of hairlessness was related to gender. Secondly, Sphinx kittens proved to be more demanding to care for than their usual brothers, and often died. And thirdly, the breeding strategy in the first catteries was unsuccessful.
This could have been the end of the sphinx story if it hadn't been for new findings. In 1975 in Minnesota, from a simple short-haired cat was born bald cat, not without humor called Epidermis. A year later, a cat was born there too. Both animals found themselves in Oregon, where Epidermis became the founder of the most elite breed lines to date. In the late 70's three new kittens were found on the streets of Toronto, near the location of the first sphinxes: a black and white cat and two cats. Unfortunately, cat's condition was also required to remove his severely damaged testicles. So this cat did not have to become an ancestor of the breed, although his beautiful type quite deserved it. But it became famous in another way: today he is a champion of longevity among sphinxes, lived a long and happy life and ended it after his 19th birthday.
Later, in order to support the genetic pool of the Canadian Sphinx breed, both in Europe and America the obtained kittens were crossed with both Sphinxes and Devon-Rex. The choice of Devon-Rex was very successful: their type and appearance was the closest to the sphinxes, and Devons were the only breed with which the first generation of bald kittens were born.
But there's a price to pay for everything. Such a massive rush of blood of another breed, although genetically close, was not a gift for the Canadian sphinxes. Unfortunately, often modern sphinxes of some lines resemble bald devons of mediocre type: thin skin, short "devon" head with eyes too round for sphinx, low, like a devon, set ears, sometimes light bony body for sphinx - a clear sign of degeneration of the breed. Such a characteristic feature of the first sphinxes wrinkled skin, making them look like little old men, less and less common in adult sphinxes. It's true that kittens are still dressed in 'bigger pajamas', but with age wrinkles diverge, remaining at best on the head, in the ideal - and on the neck. Sphinxes of many modern lines, especially European and originating from them, American, similar, more like refined porcelain figurines, rather than on the wonderful wrinkled dwarfs, as they looked in the beginning. Perhaps the most "wrinkled" Canadian sphinxes at the moment are animal lines originating from the legendary Epidermis, although they are far from their "prischur".
New natural mutations of hairlessness are rare even now on the American continent. Such animals are highly valued and try to make the most of their breeding potential. "The new bald ones are usually the pride of their kennels.
The Canadian sphinx isn't just a naked cat. Of course, lack of hair is the very first hallmark, but it's not the only one. Morphology, head, eyes and even character must meet a number of very strict criteria defined by the breed's standard. The appearance of a good sphinx is literally magical. And it's not just about hairlessness or big ears. The sphinx has a special, inherent harmony, any deviation from which makes it just a pretty cat without hair. The Canadian sphinx has an amazing softness of outlines. There are no straight lines in his figure, they are all rounded, all shapes are convex and at the same time they are fluid and smooth. In this way it resembles a Chinese statuette (perhaps that's why the second, less known name of the Canadian sphinx is "moon cat"). Ears are large and wide, and their ends are necessarily rounded. Another characteristic of the Canadian sphinxes is the thick skin that forms the folds. Kittens up to one month entirely in the "fold", including the tail and paws. With age, wrinkles are smoothed out and in adult animals they remain on the head, neck, a little on the stomach and torso, which gives them the characteristic appearance of "old men". The more creases an adult sphinx retains, the better, and the lack of creases is considered a vice. The body of cats in this breed is thick and muscular. They shouldn't be 'fried', on the contrary, their abdomen is shaped like a pear, giving the impression of a good cat eating habits. The hindquarters are longer than the front limbs, which makes the sphinx gait very distinctive. The skin feels like suede because of the very short cannon covering it. Hair is retained in all the sphinxes on the nose, the back side of the ears, a small amount at the ends of the paws and tail. In addition, the wool on these places can appear due to improper feeding, low temperatures or hormonal changes during the maturation period. The colors of the Canadian sphinxes are well distinguishable due to the strong pigmentation of the skin. The most common of them are pegged (bi- and tricolor colors, i.e. different basic color variants with white) and white (sphinxes look pink). A little less common are the solid colors and different variants of turtles. Very beautiful, as, however, and rare, colors, united in a group of "mines": Such animals with light light lightening of the main color have beautiful light blue eyes, although not as bright as our friends Siamese or blue-eyed animals white color.

It has already been said that the character of sphinxes is not a cat at all. It seems that cats they do not consider themselves: good-natured, peaceful, affectionate to man, often prefer someone from the family, not afraid of dogs and other animals, as if they have almost no preserved cat instincts, easy to learn. They perceive us as their brethren and treat us 'as equals', 'human beings'. Communication with the sphinx is always very pleasant, it's possible that due to the lack of hair the feeling of contact is created not with the animal, but with a creature standing a step closer to man - and, who knows, only outwardly?
The life expectancy of sphinxes is the same as that of other cats. Interestingly, many of the first sphinxes were long-lived.
Those interested in the genetics of hairless animals obviously know that the mutation causing hairlessness in Canadian sphinxes is recessive: in a heterozygous state, in combination with the "normal" gene present in all cats with fur, the gene of hairlessness of sphinxes is not phenotypically manifested (ie, hybrid animals of the first generation will have normal hair). The sign of hairlessness only manifests in the homozygous ("pure" from the admixture of the "normal" gene) state, when an animal has a double set of sphinx hairlessness gene, the genetic designation of which hr. The only exception to this rule is the combination with the re gene, which is responsible for the sign of wavy hair in Devonrex. In relation to it, the sphinx hairlessness gene is the dominant one, i.e. it is already phenotypically manifested in heterozygous state (e.g. in first generation hybrid animals).
But it's not that simple. The dominance of the hairlessness gene in this case is not complete. Heterozygous kittens based on this feature partially retain their hair. It can be on her feet, her tail, sometimes - to a greater or lesser extent - on her sides; as a rule, the muzzle of such cats is heavily overgrown, and the fur can go behind her eyes to form a woolen 'mask'. But the degree of overgrowth in heterozygous animals can be very different, even with seemingly the same genetic formula. This is especially evident in the first generation of hybrid kittens (Sphinx X Devon-Rex): there can be a complete layout - from almost completely naked animals to covered with wavy hair all over the body. True, in the latter case, such a kitten will lose some of its fur with age, but it will definitely remain on its tail, paws and head, perhaps a little on its sides. But a hybrid bald kitten will also have reduced short hairs that are more visible and visible than purebred sphinxes.
Interestingly, the main difference between hybrid kittens is not even the degree of maturity or type, which can also vary greatly among kittens of the same litter - from very close to the sphinx to fully 'devonian' (usually more kittens). The most telling difference is the skin. In purebred sphinx kittens, the skin is thick from birth, gathering in distinct relief folds, which makes their appearance simply unique. Hybrid kittens have much thinner skin, more like the skin of ordinary cats, folds may also be present, but not as embossed as the real sphinxes. In return crossbreeds on purebred sphinxes kittens are becoming more and more "sphinx" throughout the whole set of signs, although in each litter will always be observed split and partial return to the type of Devon-Rex, which is manifested in excess overgrowth, shortened wide head (like a bad Devon-Rex), a characteristic "Devon" fasting ears (below and slightly to the side, not up, like the sphinxes).
Among the breeders of the breed it is common to divide sphinxes into homozygous (i.e. bearing the paired hairlessness gene - hrhr) and heterozygous (bearing the hairlessness gene hr in combination with the re Devon Rex gene). At the same time, most proudly claim that their sphinxes are real, i.e. homozygous. In fact, even the presence of a pedigree in which Devon Rexes are completely absent does not guarantee homozygosity per se. There are a lot of Devon genes in the genetic pool of the breed because of the mass use of Rexes even during the formation of the breed, and to this day such knitting is not bone. It is possible to distinguish homozygous sphinx from heterozygous sphinx not by pedigree, but by appearance, especially at birth: homozygous kittens are born absolutely bald, without a sign.
It is possible to distinguish homozygous sphinx from heterozygous sphinx not by pedigree, but by appearance, especially at birth: homozygous kittens are born absolutely bald, without any signs of any kind of hair, later they have hair on the nose (but only on the nose, it does not enter the muzzle!), thin hair grows on the top half of ears and ...everything! Heterozygous sphinxes are always born with a small and very weak, but a cannon on the body (e.g. on cereal). This cannon can disappear completely after 1-2 weeks and at a later age it will be very difficult to distinguish homozygous sphinxes from heterozygous ones (provided that the latter are minimally overgrown), but in adulthood, as a rule, coat can appear again in proportion to the amount that the kitten had at birth. Perhaps more important from the breeding point of view is the general type of animal, determined by the complex influence of genes and slowly improving in directed breeding.
The recognition of the Canadian sphinxes as a breed was not easy. After the failure of sphinx breeding in the first nurseries, there was a perception that the breed was extremely unstable and unable to stabilize it. It was only a 'second wave' of breeding, which began with the repetition of the animals found, that made it possible to create this unique breed. The breed is recognized by many felinological organizations in the United States. Here's a complete list of organizations that fully recognize the breed to date:
The International Cat Association (TICA) - International Felinology Association;
American Cat Fanciers Assotiation (ACFA) - The American Cat Lovers Association;
American Cat Assotiation (ACA) - American Felinology Association;
American Assotiation of Cat Enthusiast (AACE), the American Association of Cat Enthusiasts;
United Feline Organization (UFO) - United Felinology Organization;
Canadian Cat Assotiation (CCA), Canadian Felinology Association.
Most of the sphinxes are currently registered with TICA. Since 1982, the number of sphinxes in the organization has been around 1300 and in recent years, approximately 300 new sphinxes have been added annually. But the breed is currently at a significant new stage in its development. In February this year, the CFA decided to classify the Canadian sphinxes as a special class. ("Miscellaneous class"), which means the beginning of recognition of the breed in this, the largest and most conservative organization in the United States. However, the class open to the Canadian sphinxes only entitles them to participate in CFA shows without being titled; the breed standard will be developed and approved by the organization in collaboration with the breeders for several years.
