Sphynx cat is a species of cat known for its lack of coat (fur). Cats are a naturally occurring genetic mutation; However, as briefs the sphinx cat evolved through selective breeding. The texture of the leather chamois should be because it has fine hair, or they may be completely hairless. Whiskers may be present full or broken or completely absent.
They have a short, long head and a webbed foot. Their skin will be the color of their fur, and common cat marks (solid, point, van, tabby, tortie, etc.) can be found on Sphinx cat skin. Because they have no coat, they reduce body heat more than coated cats. It makes them warm to the touch and causes them to look for sources of heat.
Sphynx cat Breeding standards
These breed values are defined by the International Cattle Association (Vaccines):
- Cube-shaped head with prominent cheek sister
- Large, lemon-shaped eyes ped
- There is not much hair inside, but the outer base is soft
- Well-muscled, medium-length strong neck
- Medium length torso, barrel-chested and full, round abdomen, sometimes called the abdomen
- Pad pads, compared to other cats, give the appearance of walking with cushions
- Whiplike, pulling off the tail from body to tip, (sometimes a fur or a fur on the entire tail, like a lion).
- Muscular body
Behavior
A male purebred Sphynx cat is in the “mink” pattern. Like a guided cat, the mink pattern shows more dark points: the tips of the ears, tail, legs, and nose. However, although the pattern indicated is completely colorless elsewhere in the body, there is some color throughout the body throughout the mink-colored and there are only a few dark points of youth. The mink pattern can be combined with any color.
Sphynx cat is known for their extroverted behavior. They show a high level of energy, intelligence, curiosity and affection for their owners. They are more like a cat’s dog, their owners are often welcomed by their owners and are friendly when meeting strangers.
History of cat breed
Contemporary breeds of Sphynx cats, also known as the Canadian sphinx, are different from Russian hairless cat breeds like Peterbald and Donsky.
Although hairless cats have been reported throughout history, breeders in Europe have been working on Sphynx cat varieties since the early 1960s. Cats, based on two different sets of hairless lines discovered in North America in the 1980s, created the size of existing Sphynx cat breeds.
The current American and European Sphinx varieties are derived from two lines of natural variation:
Dermis and Epidermis (1975) Cat cats from the Pearson family of Wadena, Minnesota
Bambi, Panki, and Paloma (1978) found cats raised in Toronto, Ontario, Canada, and by Shirley Smith
Toronto
Canada’s sphinx breed started in Toronto when a hairy kitten named Prune was born to a black and white domestic shorthair queen (Elizabeth). The kitten was reunited with her mother (something known as backcrossing), which created another nude kitten. Later some nude kittens were found, the first attempt to create a hairless breed marked cat breeding.
In 1966, after purchasing these cats and initially referring to them as “Moonstones” and “Canadian Hairless”, Ridadh Bawa, a science graduate from the University of Toronto, made a joint effort with his mother, Yanya, a longtime Siam breeder, and Kiss and Rita Tenashov’s cat. Which was later renamed “Spinax”.
Bawas and Tenhovs were the first to determine the spontaneous nature of the Sphinx gene for hair loss, and even after it was successful, converting this knowledge into a successful breeding program with cats that eventually was able to reproduce. Tenhovs were initially able to obtain new breed status through the Cat Fanciers Association (CFA), but this position was eventually rejected when the CFA Board felt that there were concerns about the fertility of the breed.
The first breeders had a rather vague idea of sphinx genetics and encountered a number of problems. The genetic pool was very limited and many kittens were killed. Most women also had problems with itching. In 1978, Ontario’s cat breeder Shirley Smith found three hairless kittens on the streets of her neighborhood.
In 1983, he sent two of them to Dr. Hugo Hernndez in the Netherlands, a white Devon Rex named Kura van Zetrophin for breeding two cats named Pucci and Paloma. As a result, the litter produced five kittens: two males of this litter (Q. Ramses and Ky. R) were used, including Panky’s half-sister Paloma.
Minnesota
The first recognized naturally occurring foundation originated in Wadena, Minnesota, as a hairless stray burn cat at the farm of Milt and Ethlyn Pearson. Pearson identified hairy cats in several liters of their domestic shorthair burning cats in the mid-1970s. Two hairless female kittens, born in 1975 and 1976, were sold to the epidermis and dermis, Oregon breeder Kim Mousec, and became an important part of the sphinx breeding program. Cats were working with the Pearson Line breeder of Minnesota Brainard, Georgia Gatenby, who outwitted Cornish Rex cats.
Genetics and reproduction
Other hairless varieties may have body shapes or moods that are different from those described above. For example, there are new hairless varieties from Russia including Don Spineaux and Peterbold, which originated from their own spontaneous gene mutation. The value of the sphinx varies between cat associations such as the International Cat Association (Vaccine), the Federation International Feline (FIF) and Cat Fansiors Association (CFA).
Breeding
DNA analysis confirmed at 27 that Diffone hairpins were produced by a separate allele of the same gene that produces short curly hair (called the “ray” allele) of the Devon Rex, while the sphinx allele has a disproportionate predominance over the Devon allele, and both are rare for wild type. The allele of Sphynx cat is called “HR” for hairless. The only approved outcross varieties of the CFA are American Shorthair and Domestic Shorthair [in Europe, mainly used for Devon Rex outcross.
Genetics
Mutations in the same gene produce the short curly coat of Diffon Rex and mutation in the same gene. Furthermore, it has been found that the Selkirk Rex cat’s curly coat is also related to this gene.
The gene encodes keratin and is responsible for the keratinization of the hair follicle. Changes in the sphinx completely degrade the function where the hair structure is damaged so that the hair can be formed but easily displaced. A residue of protein still exists in the Devon Rex mutation. The Selkirk Rex allele (Sadr) is dominant in the wild-type gene, which influences the Devon Rex allele (re) and sphinx (HR), forming its elite series: KRT71SADRE. > KRT71 +> KRT71re> KRT71hr.
Care
Although Sphynx cats lack any coat of shed or groom, they are not maintenance-free. Body oils, which are usually absorbed by the hair, speed up the skin. As a result, regular baths are usually required weekly or bi-weekly.
Care should be taken to limit the exposure of the sphinx cat to outdoor sunlight in the long run, as they can develop sunburn and skin damage like humans. In general, sphinx cats should never be allowed outside, as there are limited ways to store body heat during the winter. In some climates, owners provide coats or other clothing to help protect them from body heat in winter.
Sphynx cats are not necessarily hypologic, even when other cats breed extensively. Cats allergies are driven by a protein called Fell D1, not cat hair itself. Fail D1 is a protein that is found mainly in the saliva of the cat and in the sebaceous gland. Individuals with cat allergies may react worse to direct contact with the Sphinx cats than other breeds.
Although there are reports that some people with allergies successfully tolerate the Sphinx cat, they have less than one allergic reaction, according to David Rosenstreich, director of the Department of Allergy and Immunology at the Albert Einstein College of Medicine and Montefiore Medical, Bronx, New York City, New York City.
These positive reports are like being sensitive That could be the case, where the “hairless” cat gave hope to the cat owner for trying to own a cat and eventually led to a positive situation of their own adaptation.
Spinks cats may have more ear wax than most hairy domestic cats because they have very little hair in their ears. Dirt, skin oil (sebum) and ear wax accumulate in the ears and usually need to be cleaned weekly before bath time.
The Sphinx breed is frozen under oil and debris under the nails as it does not fold over the nails of the skin, so the nails and the surrounding skin of the nail need to be properly cleaned [18] because of these reasons more grooming may be needed than a typical domestic cat. Special products have been developed for this cat, though they still require more decoration than most breeds.
Health problems
Canadian sphinxes have faced challenges due to their lack of protective fur, which can cause skin cancer problems when exposed to sunlight for a long time.
Hair loss can be a cause of health problems with cats due to susceptibility to respiratory infections in the first weeks of life. Named breeders should not allow their kittens to move into a new home until they are at least 14 weeks old, to ensure that the kitten is mature enough to deal with the new environment.
Hypertrophic cardiomyopathy
Genetic disorders of the genus are examples of hypertrophic cardiomyopathy (HCM). Other domesticated cats that have a tendency for HCM include Persian, Radle, Norwegian Forest Cat, Siberian Cat, British Shorthair, and Maine Coon.
However, any domesticated cat of mixed breed can acquire HCM. Studies to understand the link between fertility and disorder are being studied. Cats are screened for HCM disease with echocardiography (ultrasound of the heart), as well as additional tests performed by an electronic cardiologist, including electrocardiograms (ECG, ECG), chest radiographs (X-rays), and / or blood tests.
Sphinx cats have a higher rate of heart disease, such as HCM or mitral valve dysplasia ায় According to a study of 5 sphinx cats in 2002, 34% had abnormal heart failure, 16 cats with mitral valve dysplasia and 23 cats had HCM.
These expansions average 2. Found in 2-year-old cats. Male cats develop the more severe disease than female cats and often develop early, with the average age of males being 6 months compared to females 25 months. Since this variety is more prone to genetic heart disease, many breeders will recommend screening for annual HCM.
As HCM advances to an advanced stage, cats may experience congestive heart failure (CHF) or thromboembolism.
Congenital Myasthenic Syndrome
Congenital Myasthenic Syndrome (CMS) (formerly known as muscular dystrophy, myopathy, or spasticity) is a type of inherited neuromuscular disorder found in varieties of these breeds, as well as sparks and Devon Rex cats.
This condition has also been described but is rarely seen. Cats infected with CMS show muscle weakness and fatigue, as well as ventrofixation of the head and neck, head and chest and scalp protrusions.
