Hairless · Rank #7 Most Popular Cat Breed
Sphynx
The Sphynx is a hairless breed that first appeared as a natural genetic mutation in Toronto, Canada in 1966, and was subsequently developed through selective breeding. Despite their lack of fur, Sphynx cats have a warm, suede-like skin and are known for being extraordinarily affectionate and people-oriented. They are among the most extroverted of all cat breeds.

Feeding Guide
Because the Sphynx lacks a coat, it must burn more calories to maintain body temperature, giving it a higher metabolic rate than most cats. They typically require more food than similarly sized coated breeds and do well on calorie-dense, high-protein diets. Despite their higher needs, portion monitoring prevents excessive weight gain.
Water Needs
Sphynx cats can be prone to hypertrophic cardiomyopathy, and good hydration supports cardiovascular and kidney health. They should always have access to fresh water; wet food as part of their diet is particularly beneficial for this breed.
Exercise Guide
Sphynx cats are highly energetic and need substantial daily activity—at least 30 minutes of interactive play. They enjoy climbing, acrobatic play, and games that challenge them mentally. Their lack of insulating fur means exercise in warm, draft-free environments is preferable.
Common Health Issues in Sphynxs
- Hypertrophic cardiomyopathy (HCM)
- Skin conditions and sunburn
- Dental disease
- Respiratory infections
- Hereditary myopathy
These are conditions commonly associated with the breed, not a diagnosis for your individual pet.
