Where do hairless cats come from? The answer points to a unique genetic twist originating with a single kitten born in Toronto in 1966. This kitten was the proto-Sphynx, the progenitor of not just the Sphynx breed but a family of hairless felines that now grace homes worldwide. Delving into their origins, this article reveals the remarkable history of these captivating breeds.

Key Takeaways

  • Hairless cats like the Sphynx have a genetic mutation in the KRT71 gene, which affects hair follicle development and leads to their unique appearance.
  • Different hairless breeds have evolved over time, including the Sphynx, Donskoy, and Peterbald, each with its own distinct characteristics and varying skin and fur types.
  • Caring for hairless cats requires special attention to their diet, grooming, skin care, and health monitoring due to their lack of fur and higher metabolic rates.

The Hairless Cat Phenomenon: A Genetic Mutation

The striking physical appearance of hairless cats, like the famous Sphynx, is due to a natural genetic mutation in the KRT71 gene. This gene plays a crucial role in hair formation, and when it mutates, it affects the development of hair follicles, leading to a lack of fur in cats.

The mutation disrupts the inner root sheath of the hair follicle, which is critical for anchoring hair, meaning these cats have a unique look with their wrinkled skin and lack of a typical furry coat. This fascinating genetic story involving the KRT71 gene is why we have the pleasure of enjoying these special cats today.

While their baldness is the most noticeable feature, it’s not the only one that sets these cats apart. Hairless cats have a distinctive appearance that goes beyond their lack of fur. They have:

  • Skin that is the color their fur would be, often with a texture akin to warm chamois
  • A muscular body
  • A wedge-shaped head
  • Large ears
  • Striking, lemon-shaped eyes
  • Neat, rounded paws that make them look like they’re always wearing mittens.

The KRT71 Gene

To really understand hairless cats, we need to dive a little deeper into the science behind their unique appearance. The key player in this story is the KRT71 gene. This gene is fundamental in developing hair follicles, making it a pivotal player in the hair formation process. When this gene mutates, it disrupts normal protein encoding, which is essential for functional hair follicles. This mutation results in the absence of hair in affected cats.

The mutation in the KRT71 gene alters the structures within the α-helical rod domain of the KRT71 protein. This impedes the formation of normal hair in cats. But how does this mutation get passed down? It follows an inheritance pattern.


For a kitten to be hairless, it must inherit the recessive mutated KRT71 gene from both parents; the mother and father must carry the gene for their offspring to be hairless.

The First Hairless Kitten: Prune

The journey of hairless cats began with an unsolicited genetic event in Toronto, Canada, in 1966. A domestic cat gave birth to a hairless kitten, who was given the name Prune.

This was not a result of human breeding practices, but a natural genetic mutation that occurred spontaneously. Prune’s birth sparked interest among cat lovers, igniting deliberate breeding programs aiming to create more cats possessing the hairless trait.

Prune’s legacy has continued, with the Sphynx breed tracing its origins back to him. Over time, the breed has been recognized as the Canadian Sphynx, celebrating its unique place in feline history. Today, Sphynx cats are loved and cherished by many for their distinctive personalities and compelling looks.

Evolution of Hairless Cat Breeds

The story of hairless cats doesn’t stop with the Sphynx. As fascinating as they are, the Sphynx isn’t the only hairless cat breed out there. Over time, through selective breeding and crossbreeding, other hairless cat breeds, such as the Donskoy and Peterbald, have evolved. Each breed has a unique story, all tracing back to the discovery of that first hairless kitten, Prune.

The Sphynx breed was developed in the 1960s by selectively breeding hairless cats that resulted from a natural genetic mutation. Two separate sets of hairless felines discovered in the 1970s in Toronto, Ontario, and Wadena, Minnesota, significantly contributed to the initial breeding efforts of the Sphynx breed.

The pivotal genetic lines for the purebred sphynx cats include Dermis and Epidermis from Minnesota, and Bambi, Punkie, and Paloma from Ontario.

The Sphynx

The Sphynx breed, also known as the Sphynx cat breed, holds a unique place in the world of hairless cats. The breed originated in Canada in 1966. This was when a domestic cat gave birth to a hairless kitten, the result of a natural genetic mutation. Despite early genetic hurdles and health issues, the breed was developed from this mutation. Sphynx cats are known for:

  • their large eyes and ears
  • long legs and tail
  • rounded paws
  • their lack of fur

Their coat, if you can call it that, feels peach-like or similar to chamois and may feature a small puff of hair at the tip of the tail or on the ears and nose.

But it’s not just their looks that make Sphynx cats stand out. They’re also known for their friendly and affectionate nature. Many liken their social behavior to that of dogs. As a sphynx cat thrives on human company, they require 15 to 30 minutes of playtime daily to keep them fit and engaged.

The Donskoy

Another fascinating hairless breed is the Donskoy, discovered in Russia in 1987 by cat breeder Elena Kovaleva. Also known as the Don Sphynx or Russian Hairless, Donskoy cats are characterized by their strong bodies, muscular necks, and wedge-shaped heads, making them a unique alternative to the Canadian Hairless. These cats have a distinct appearance with almond-shaped eyes, long webbed toes, and wrinkled skin, particularly on their face, neck, chest, and the base of the tail.

Their skin and eye color can vary widely, with faded skin patterns and eye colors ranging from blue to brown. Donskoy cats may develop a faint fur coat during winter, which is typically shed as temperatures rise. There are four coat categories for Donskoy cats:

  1. Rubber Bald
  2. Flock Coat
  3. Velour Coat
  4. Brush Coat

Each category indicates different levels of hairlessness or coat texture.

Known for their social nature, intelligence, and trainability, Donskoy cats are well-suited for family environments and interactions with children.

The Peterbald

The Peterbald breed, developed in St Petersburg in 1994, is another fascinating hairless breed. It was created by crossing a Donskoy with an Oriental Shorthair, resulting in a slender, affectionate cat with varying coat types.

Peterbald cats possess distinctive physical features similar to the Oriental Shorthair, including a slender, muscular build, large pointed ears, and almond-shaped eyes. Their coat types range from completely hairless to having various textures such as velour and the unique brush fur.

Peterbalds are known for their affectionate nature and demonstrate a loyalty akin to dogs. They have a peaceful, docile temperament that makes them well-suited to family environments.

Peterbald cats can undergo changes in their hair over time…

Generally considered to be a healthy breed, some Peterbald cats can undergo changes in their hair over time, with kittens born with fur possibly becoming more hairless as they mature or experiencing changes in coat texture, such as the development of the short, wiry brush fur.

Other Hairless Hybrids

In addition to the Sphynx, Donskoy, and Peterbald, there are other hairless hybrids that have been created by crossing hairless breeds with other cat breeds. One of these is the Ukrainian Levkoy, known for its inward-folding ears and angular head shape. This breed emerged in Ukraine and was developed by crossing a Donskoy with a Scottish Fold.

Ukrainian Levkoys possess a medium to long muscular body with an arched back, oval chest, and long, mobile toes. Their friendly and intelligent personality makes them sociable pets, with males exhibiting notably larger sizes than females.

Other notable hairless hybrids include:

  • The Elf cat, a hybrid of the Sphynx with American Curl
  • The Bambino, a unique blend of the Sphynx with the Munchkin, distinctive for their unique ear shapes and short stature respectively
  • The Minskin cat, with a similar Sphynx-Munchkin lineage as the Bambino but featuring fur points on its face, ears, nose, legs, and tail

Each of these breeds adds a unique flavor to the world of hairless cats, showcasing the diversity and adaptability of these remarkable creatures.

Caring for Hairless Cats

Caring for hairless cats requires a slightly different approach compared to their furry counterparts. Due to their lack of fur, they are sensitive to extreme temperatures and require protective measures such as clothing or heated beds in cold environments. They must also be shielded from potential overheating and sunburn in warmer climates.

Given their lack of fur, hairless cats like the Sphynx are prone to accumulating oils on their skin, making grooming with gentle, soap-free, natural shampoos and regular bathing important to maintain their skin soft and healthy.

After bathing, it’s crucial to thoroughly dry a hairless cat with a warm towel to prevent skin issues and ensure they do not get cold. The diet of a hairless cat must also be carefully managed as it has a direct impact on the health and condition of their distinctive skin.

They have higher metabolic rates, which means they burn calories at a faster rate than other cats. Therefore, they need a diet that is richer in calories and high in protein to maintain their body temperature and meet their energy needs.

Grooming and Skin Care

When it comes to grooming and skin care, hairless cats require special attention. Here are some important grooming tasks for hairless cats:

  1. Regular bathing is required to manage oil accumulation on the skin, which helps reduce allergens present on their skin.
  2. Hairless cats’ ears can gather dirt and wax more readily than those with hair, making ear cleaning a vital part of their grooming routine.
  3. Regular nail trimming is also important for maintaining the health and comfort of hairless cats.

To properly care for a hairless cat, owners should be equipped with gentle cat shampoo, a no-slip bathtub mat, and clothing like cat sweaters and T-shirts to protect their skin. These items will help keep their skin healthy and free from irritations or infections. Regular grooming is not just about keeping hairless cats clean, but also about keeping them comfortable and healthy.

Diet and Exercise Requirements

Just like their grooming needs, the diet and exercise requirements of hairless cats are also unique. Hairless cats, such as the Sphynx and Peterbald breeds, have higher metabolic rates. This means they require a diet that is richer in calories to help maintain their body temperature. Sphynx cats, which exemplify hairless breeds, require a diet that is not only calorie-rich but also high in protein to accommodate their energy needs.

Due to their unique dietary needs, a Sphynx may need more frequent meals, underlining the importance of a tailored feeding schedule for individual hairless cats. To fulfill their exercise requirements, hairless cats benefit from regular playtime and activities involving interactive toys, which cater to their energetic and playful nature. Regular exercise helps keep them physically fit and mentally stimulated, promoting overall health and well-being.

Health Considerations

Hairless cats, such as the Sphynx, are prone to a variety of health conditions that require attentive care and regular veterinary oversight. These cats may experience issues such as:

  • Skin rashes
  • Fungal infections
  • Hypertrophic cardiomyopathy (HCM)
  • Dental and oral health problems

To mitigate these health risks, regular veterinary check-ups and specific health screenings, especially for HCM and dental care, are crucial for maintaining their well-being.

Without fur to mask symptoms, more vigilant observation is necessary to catch early signs of health issues in hairless cats. Owners should keep an eye out for changes in their cat’s behavior, eating habits, and overall appearance. Any unusual signs should be promptly reported to a veterinarian for a thorough assessment.

Being proactive about their health can help ensure that these unique felines live long, healthy lives.

Hairless Cats and Allergies

Many people believe that hairless cats are completely hypoallergenic, but this is a common misconception. While it’s true that hairless cats may not trigger allergies as much as other cats, they are not completely hypoallergenic.

They still produce skin cells, known as dander, and the protein Fel d 1, which are common allergens. Hairless cats produce Fel d 1, the main protein responsible for most cat allergies, which is found in their saliva, urine, and skin.

Interestingly, the levels of Fel d 1 allergen can be lower in female and neutered male hairless cats compared to non-neutered males, potentially reducing the allergenic effects. To manage allergy symptoms, here are some tips:

  • Create cat-free zones in your home where you spend a lot of time.
  • Clean areas where hairless cats spend time regularly to minimize the spread of allergens.
  • Consider using self-cleaning litter boxes to help manage allergies.

While hairless cats may be a better option for those with allergies, they are not completely allergen-free.


In conclusion, hairless cats are undeniably fascinating creatures. Their unique genetic mutation, the evolution of different hairless breeds, and their distinctive grooming and care requirements all contribute to their intrigue. While they are not completely hypoallergenic, they may be a better choice for individuals with allergies. Ethical breeding and adoption practices are key to ensuring these extraordinary felines continue to thrive. We hope this blog post has been informative and enjoyable, inspiring you to learn more about these remarkable cats.
