Sphynx
SFINKS
Extroverted, Energetic, Silly, Attention-seeking. Origin: Canada (Toronto, natural mutation).
An adult Sphynx weighs 8-14 lbs (male) or 6-9 lbs (female), needs 150-390 calories daily, and lives 8-14 yrs. The breed's primary health watch is hypertrophic cardiomyopathy. All numbers below come from breed standards and NRC 2006 veterinary nutrition formulas.
Nutrition and feeding
A typical adult Sphynx needs 150 to 390 calories per day. An average male (11 lbs / 5.0 kg) needs around 280 kcal; a female (8 lbs / 3.4 kg) roughly 210 kcal.

Health profile
The Sphynx is a hairless breed that requires specific care different from coated cats. Without fur to absorb skin oils, they need regular bathing (weekly or biweekly) to prevent oil buildup and skin problems. They are temperature-sensitive and need warm environments. Hypertrophic cardiomyopathy (HCM) is the most significant health concern. Skin conditions (sunburn, acne, fungal infections) are common without proper skin care. Life expectancy is 12 to 14 years.
Exercise and activity
Sphynx cats are high-energy, social, and constantly in motion. They climb, jump, and seek attention relentlessly. Their lack of fur means they burn more calories maintaining body temperature, which fuels their active behavior. Multiple play sessions daily, climbing structures, and puzzle feeders are essential. They are natural performers who enjoy an audience.
Care and traits
Sphynx cats have a hairless (actually covered in fine peach-fuzz down) coat. Origin: Canada (Toronto, natural mutation).
Not truly hairless; covered in fine down that feels like warm suede. Their skin produces oils that aren't absorbed by fur, requiring weekly baths. Ears accumulate wax quickly and need regular cleaning. They sunburn easily; keep them indoors or use pet-safe sunscreen. Their high metabolism means they're always warm and always hungry. They need sweaters in cold weather and heated beds.
The Sphynx is well-suited for families with children. They are typically patient and tolerant, though all cat-child interactions should be supervised until children learn appropriate handling. Teaching children to respect the cat's space and body language prevents most problems.

Frequently asked questions
A healthy adult Sphynx requires 150 to 390 calories per day. An average individual at 11 lbs falls near the middle of that range. Two measured meals daily keeps most medium cats at a healthy weight. Avoid free-feeding unless your cat self-regulates well, which many do not. Use our calorie calculator with your cat's actual weight for a personalized number.
Males: 8-14 lbs (3.6–6.4 kg). Females: 6-9 lbs (2.7–4.1 kg). Feel for ribs along the sides. They should be easy to find under a thin layer of flesh. View from above: a visible waist narrowing behind the ribs indicates healthy condition.
The Sphynx's most significant breed-specific health concern is hypertrophic cardiomyopathy. HCM causes the heart muscle to thicken, reducing its efficiency. Screening via echocardiogram can detect it before symptoms appear. Annual cardiac checks are recommended for breeds with known HCM prevalence. Other conditions to monitor include hereditary myopathy, skin conditions (sunburn, oil buildup), urticaria pigmentosa. Not every Sphynx will develop these conditions, but awareness and regular vet checkups make a real difference.
Moderate play needs that most owners can easily meet. One or two interactive play sessions of 10-15 minutes daily, combined with access to a cat tree and window perch, keeps this breed content. They enjoy play but are equally happy relaxing. Every cat, regardless of breed, benefits from some daily play and enrichment. Even five minutes of chasing a wand toy is better than nothing.
