The Sphynx cat (pronounced SFINKS, / ˈ s f ɪ ŋ k s /) also known as the Canadian Sphynx, is a breed of cat known for its lack of fur.Hairlessness in cats is a naturally occurring genetic mutation, and the Sphynx was developed through selective breeding of these animals, starting in the 1960s.
Cat fur can be short, long, curly, or hairless. Most cats are short-haired, like their ancestor. [40] The fur can naturally come in three types of hairs; guard, awn, and down hair. The length, density and proportions of these three hairs varies greatly between breeds, and in some cats only one or two types are found. [40] [41]
In most mammals, humans included, red hair is caused by mutations in a cell surface protein (Mc1r) that determines whether melanocytes (a type of skin cell) will produce a dark pigment or a ...
Another of the hairless cat breeds, the Peterbald is an athletic cat that is also considered curious, lively, intelligent, and social. Peterbald kittens usually have some hair, but lose it as they ...
At times, when a hairless domesticated animal is discovered, usually owing to a naturally occurring genetic mutation, humans may intentionally inbreed those hairless individuals and, after multiple generations, artificially create hairless breeds. There are several breeds of hairless cats, perhaps the most commonly known being the Sphynx cat.
The Donskoy cat, also known as Don Sphynx or Russian Hairless, is a hairless cat breed of Russian origin. [1] It is not related to the better-known Sphynx cat (Canadian Hairless) whose characteristic hairlessness is caused by a recessive mutation in the keratin 71 gene. The Donskoy's hairlessness, on the other hand, is caused by a dominant ...
Human eyes have three types of cones: red-sensing, green-sensing and blue-sensing. Feline eyes also contain the same color-sensing cones as humans , but this doesn't mean our visions are the same ...
As a result, both red cats and the patches of red on tortoiseshell cats will always show tabby patterning, though sometimes the stripes are muted—especially in cream and blue/cream cats due to the pigment dilution. The mackerel pattern and its T m allele at the tabby gene locus is dominant over the classic (or blotched) allele, T b.
