Sphynx Cat ???? Injection Without Pain ???? EP - 485

Sources of information:The Sphynx cat 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.

According to breed standards, the skin should have the texture of chamois leather, as it has fine hairs, or the cat may be completely hairless. Whiskers may be present, either whole or broken, or may be totally absent. The cats have a narrow, long head and webbed feet. Their skin is the color that their fur would be, and all the usual cat markings (solid, point, van, tabby, tortie, etc.) may be found on the Sphynx cat's skin. Because they have no fur, Sphynx cats lose body heat more readily than coated cats, making them both warm to the touch and prone to seeking out warm places.

Behavior
Sphynx are known for their extroverted behavior. They display a high level of energy, intelligence, curiosity and affection for their owners. They are one of the more dog-like breeds of cats, frequently greeting their owners at the door and friendly when meeting strangers.

Health issues
The Sphynx faces challenges because of its lack of protective fur. Skin cancer may be a problem if exposed to sunlight for long durations of time.
The lack of hair can cause health issues with kittens in the first weeks of life because of susceptibility to respiratory infections. Reputable breeders should not let their kittens go to new homes without being at least 14 weeks of age to ensure the kitten is mature enough to cope in a new environment.

Genetics and breeding
Other hairless breeds may have body shapes or temperaments that differ from those of Sphynx standards. There are, for example, new hairless breeds, including the Don Sphynx and the Peterbald from Russia, which arose from their own spontaneous gene mutations. The standard for the Sphynx differs between cat associations such as The International Cat Association TICA, Fédération Internationale Féline FIFE and Cat Fanciers' Association CFA.

Breeding
In 2010, DNA analysis confirmed that Sphynx hairlessness was produced by a different allele of the same gene that produces the short curly hair of the Devon Rex , with the Sphynx's allele being incompletely dominant over the Devon allele and both being recessive to the wild type. The Sphynx's allele is termed "hr", for hairless. The only allowable outcross breeds in the CFA are now the American Shorthair and Domestic Shorthair.[citation needed] Other associations may vary, and the Russian Blue is a permitted outcross in the Governing Council of the Cat Fancy GCCF. In Europe, mainly the Devon Rex has been used for outcrosses.

Care
Although Sphynx cats lack a coat to shed or groom, they are not maintenance-free. Body oils, which would normally be absorbed by the hair, tend to build up on the skin. As a result, regular bathing is usually necessary weekly or bi-weekly. Care should be taken to limit the Sphynx cat's exposure to outdoor sunlight at length, as they can develop sunburn and skin damage similar to that of humans. In general, Sphynx cats should never be allowed outdoors unattended, as they have limited means to conserve body heat when it is cold. In some climates, owners provide coats or other clothing in the winter to help them conserve body heat.

While they lack much of the fur of other cat breeds, Sphynxes are not necessarily hypoallergenic. Allergies to cats are triggered by a protein called Fel d1, not cat hair itself. Fel d1 is a protein primarily found in cat saliva and sebaceous glands. Those with cat allergies may react to direct contact with Sphynx cats. Even though reports exist that some people with allergies successfully tolerate Sphynx cats, they are fewer than those who have allergic reactions.

Sphynx cats can also have more ear wax than most hairy domestic cats because they have little to no hair in their ears. Dirt, skin oils (sebum) and ear wax accumulates in the ears, and needs to be cleaned out on a weekly basis, usually before bath time.

The Sphynx breed also tends to accumulate oils and debris under the nails as well as the skin fold above the nail due to the lack of fur, so, like the ears, the nails and surrounding skin folds need to be cleaned properly as well. Due to these factors the breed may require more grooming than a typical domestic cat with fur. Specialty products for this cat have been developed, though they still require more grooming than most breeds.
