The breeds of sphinxes that are now popular are modern cats, but they also had distant ancestors. Natural, natural mutations among cats have been observed over the past hundred years, and most likely they happened much earlier. Pictures of a Mexican hairless cat appeared in the Book of the Cat magazine, published back in 1903 by Franz Simpson. He wrote, they were a brother and a sister who were given away by the Indians, who assured us that they were the last cats of the Aztecs, and they were bred only in Mexico City. But no one was interested in them, and they sunk into oblivion.
Other cases of the appearance of hairless cats were noted in France, Morocco, Australia, and Russia.
In the 70s of the last century, two different mutations of hairless cats were discovered and both laid the foundation for the current Canadian sphynx. The modern sphinx differs from similar breeds, such as Peterbald and Don Sphinx, primarily genetically.
In 1966, in Ontario (Canada), a pair of domestic short-haired cats gave birth to offspring, among which was a hairless kitten named Prune.
The kitten was brought to his mother (backcrossing), as a result of which several hairless kittens were born. The breed development program began, and in 1970, the CFA granted provisional status to the Canadian Sphynx. However, the following year it was recalled due to health problems in cats. On this, the line almost died out. In the second half of the 70s, a Siamese cat breeder, Shirley Smith, found three hairless kittens on the streets of Toronto. It is believed that these are the heirs of the very cats, although there is no direct evidence for this. The cat was castrated, and the cats Punk and Paloma were sent to Dr. Hugo Hernandez, in Holland. The offspring of these kittens developed in Europe and America, by crossing with Devon Rex, and then came to the United States.
At the same time, in 1974, farmers Milt and Ethilin Pearson, from Minnesota, found three hairless kittens among kittens born of their brown tabby cat. It was a cat named Epidermis and a cat nicknamed (Dermis), and they were eventually sold to Oregon, the scout Kim Kim.
Muske’s first attempt to cross-breed these cats with American Shorthair gave only kittens with normal hair. On the advice of Dr. Solveig Pfluger, Muske crossed Epidermis with one of her offspring, resulting in three litterless kittens in the litter. This proved that the gene is recessive and must be in both parents in order to be passed on to offspring.
