Donskoy Cat: Hairless by a Dominant Gene

The Donskoy, also known as the Don Sphynx or Don Hairless, is a Russian hairless cat breed that arose independently of the Canadian Sphynx and carries a completely different gene responsible for hairlessness. Where the Sphynx's hairlessness results from a recessive mutation, the Donskoy's hairlessness is dominant, meaning one copy of the gene is sufficient to produce hairlessness. The two breeds look superficially similar but are genetically unrelated in their defining characteristic.

The Donskoy is the parent breed of the Peterbald, created by crossing Donskoy with Oriental Shorthairs. Both breeds share the dominant hairlessness gene.

Origins: A Found Cat in Russia

The Donskoy originates from a chance discovery. In 1987 in Rostov-on-Don, Russia, Elena Kovaleva rescued a kitten, which she named Varvara. At around four months of age, the kitten began to lose fur.

When Varvara was eventually bred, some of her kittens were born without hair, confirming that the hair loss was genetic rather than a disease or parasite. These kittens became the founding stock of the breed, which was recognised first by the World Cat Federation (WCF) and later by TICA.

The breed is named for the Don River region of Russia where Varvara was found.

Dominant vs Recessive Hairlessness

The genetic distinction between the Donskoy and Sphynx hairlessness is fundamental and practically important for breeders:

Sphynx hairlessness: Caused by a recessive mutation. A cat must inherit two copies (one from each parent) to be hairless. One copy produces a normal-coated cat that is a carrier.

Donskoy hairlessness: Caused by a dominant mutation. One copy is sufficient to produce hairlessness.

In Donskoy breeding, when two hairless Donskoys are bred:

• 25% of offspring may be homozygous (two dominant hairless genes), a form that could cause feline ectodermal dysplasia, with problems such as poor dentition and a compromised ability to lactate or sweat
• 50% will be heterozygous (one dominant hairless gene), standard Donskoy hairlessness
• 25% will be non-hairless (two normal genes), normal-coated cats

Coat Varieties

Like the Peterbald, the Donskoy has four coat varieties, all resulting from the expression of the dominant hairlessness gene at varying levels:

Rubber bald (born bald): Completely hairless from birth. The skin has a warm, suede-like feel. Stays bald throughout life.

Flocked: Born with a light, peach-fuzz-like coat. These cats often lose the fuzz as they grow and become completely bald.

Velour: Born with a short, wavy coat and a bald spot on top of the head. The wavy coat is short-lived and is usually lost within the first year. Some retain a little fuzz on the face, legs and tail; others become completely bald.

Brush: Born with a short, bristly or wiry coat, with bald spots on the head, neck and back. These cats do not lose the rest of their fur as they grow.

Skin Characteristics

The Donskoy's bare skin has several distinctive properties:

Warmth. Hairless cats have a higher surface temperature than furred cats, this is not due to elevated body temperature but to the absence of insulating fur between skin and environment. Being held by a Donskoy-owner is often described as holding a warm living cushion.

Skin folds and wrinkles. The Donskoy has particularly prominent skin folding on the forehead, neck and body, creating a characteristic wrinkled appearance. These folds require attention during bathing to clean accumulated skin oils and debris.

Elastic skin. The Donskoy's skin has notable elasticity, when stretched gently it returns to position. This has been commented on as an unusual property compared to most domestic cats.

Temperament

Social, affectionate and people-oriented, the Donskoy exemplifies a consistent trait across hairless cat breeds. This trait might reflect the fact that the breed needs human cooperation for warmth and could have been selected for sociable individuals.

Key characteristics:

Warmth-seeking. Donskoy cats actively seek warm places, laps, under blankets, sunny windows, next to radiators. This thermoregulatory behaviour is practical given the absence of insulating fur.

Social and affectionate. The breed does not do well with prolonged isolation. It forms close bonds with its family and seeks interaction.

Playful and curious. Active throughout life with high engagement with interactive play.

Tolerant. Generally tolerant of handling and new situations. Good with children and other animals.

Care Requirements

Bathing. Regular bathing with a mild shampoo is usual, though over-bathing can make the skin oily. Without fur, skin oils and dust accumulate on the surface. The skin folds require particular attention.

Ear cleaning. The ears lack fur to filter dust and accumulate more debris than furred cats. Regular ear cleaning with a veterinarian-approved ear cleaner is recommended.

Temperature management. Indoor-only is strongly recommended. The breed requires warm environments, outdoor exposure in cold weather risks hypothermia.

Sun protection. To prevent sunburn, direct and extended sun exposure should be avoided.
