can sphynx cats have hair

The main feature of a Sphynx is its lack of a fur coat. The cats are not, however, entirely hairless but covered with fine, downy hair that is said to be like a peach skin. This cat has no whiskers or eyelashes. The skin is wrinkled on parts of the head, body and legs but should be taut everywhere else.

Why are Sphynx cats hairless?

It’s due to a mutation in the gene that is responsible for providing hairs with their keratin protein as they emerge from the follicle,” said Charlotte Corney, zookeeper and founder of TheWildheartTrust. “The hair is formed, but it has a weaker structure and becomes easily damaged and dislodged.”

Since their first known sighting in Toronto in 1966, when a domestic cat gave birth to a hairless kitten that was later determined to be the product of a spontaneous genetic mutation, sphynx cats were initially known as the Canadian Hairless. The first hairless cat breeding program was started by the cat, appropriately named “Prune.” Though it’s unclear if Prune or other cats with this genetic mutation are the ancestors of all contemporary hairless cats,

Although cats can naturally carry this genetic mutation, the Sphynx breed was created in the 1960s through selective breeding for this characteristic. While some Sphynx cats have short, downy fur all over their bodies or in specific places, others are completely bald, according to Corney

The recessive mutation specifically affects the keratin 71 gene (KRT71), which is essential for the development of hair. It belongs to a family of type II keratins found in all mammalian epithelial cells, which line the body’s surfaces and function as a kind of protective barrier. A protein that is expressed in the hair follicle’s inner root sheath is encoded by KRT71.

In biology, a gene is essentially turned on when it is expressed. The body produces proteins that are coded for by the DNA when instructions in the DNA are translated into the structures that are present and function in the cell. Clever.

Other phenotypes (a set of characteristics or traits of an organism) have been recorded as a result of mutations in KRT71. Previous studies have found that this gene is also responsible for curly/wavy phenotypes in dogs, mice, and rats.

Why does my Sphynx cat have fur?

They have a recessive gene mutation that causes them to have the characteristic lack of hair. In other words, a Sphynx cat needs to have two recessive alleles of the gene in order to be born hairless. The keratin 71 (KRT71) gene, which codes for the synthesis of the keratin protein, is the reason for their hairlessness. For the Sphynx, the protein doesnt function. The follicle is unable to hold the hair in place, but it doesn’t mean hair cannot grow.

Other breeds, like the Devon Rex, are also impacted by the KRT71 gene. In this breeds, the gene functions, but only a little. They have some hair, but not as much as other breeds because of this.

No dominant alleles are allowed because the Sphynx cat’s hairlessness is caused by a recessive gene. The kitten will have hair if either parent carries the dominant allele, either SS or Ss. A true Sphynx must be born with double recessive genes (ss) in both parents.

The presence of a dominant allele (SS or Ss) will cause hair to grow because two hairless Sphynx cats (ss) must be crossed to sire a hairless Sphynx cat. This implies that if a Sphynx cat crosses with a hairy cat, the resultant cat may also have hair in addition to having Sphynx-like features. Because of this, it’s likely that your Sphynx cat is a mixed-breed cat rather than a purebred Sphynx if they have hair.

Another reason your Sphynx cat might have hair is if they are mistaken for a different breed that is similar to them. Similar in appearance is the Donskoy cat, sometimes referred to as the Russian Hairless or Don Sphynx. They may have some hair at birth because their hairless characteristic is the result of a dominant mutation. This can be grouped into four types of coat:

  • Brush: these have the most hair. They have it from birth, and over time, their head, neck, and upper back gradually lose it.
  • During their first year of life, velour animals lose their woolly hair, leaving behind some short hair in areas like their faces, tails, and legs.
  • Flocked: they are born without hair but with a velvety down that fades with age.
  • Rubber bald: they are totally hairless cats from birth.

What do Sphynx cats feel like?

Sphynx cats are as colorful as their furry counterparts, with coats that resemble peaches, fuzzy down, or chamois. They occasionally might have a little bit more hair on the tips of their ears or nose, as well as a little puff at the end of their tail. Sphynx cats are frequently compared to heated hot water bottles with suede coverings!

FAQ

Can Sphynx cats get fur?

Sphynx cats are a breed known for their lack of fur. However, it is not entirely accurate to say that they are completely hairless. While most sphynxes have very little to no hair on their bodies, they can have a fine downy fuzz that gives them a warm and soft feel when touched.

Why can’t Sphynx cats grow hair?

Some Sphynx cats are completely bald, while others have short downy fur over their bodies or in isolated areas,” said Corney. Specifically, the recessive mutation is in the keratin 71 gene (KRT71), which plays a key role in hair formation.

Why do Sphynx cats have no hair?

The Sphynx’s hairlessness is produced by a mutation in the same gene that produces the short curly coat of the Devon Rex. Moreover, it was found that the curly coat of Selkirk Rex cats is also associated with this gene. The gene encodes keratin 71 (KRT71) and is responsible for the keratinization of the hair follicle.

Are Sphynx kittens born with fur?

Donskoy. Also known as the Don Sphynx, the Donskoy is an adorable hairless cat breed with wrinkly skin, big ears, long webbed toes and endearing almond shaped eyes. Interestingly, some kittens are born with coats and lose it as they get older.
