Visual Differences
Telling a Peterbald from a Sphynx
Both are hairless breeds with big ears. Sphynx have a rounded wedge head, a barrel-chested body, lemon-shaped eyes, and thick paw pads. Peterbalds have an Oriental wedge head, a svelte tubular body, and five possible coat types instead of one uniform look.
Peterbald Key Markers
- Five coat types per the TICA standard — bald (completely hairless), chamois (fine suede-like down), flock (velour-like fuzz with no guard hairs), brush (short wiry or wavy hair), and straight (a regular coat); one litter can produce several types
- Long wedge head with a straight profile, the classic Oriental shape — a long muzzle and a strong chin
- Very large, wide-set, almond-shaped ears, set to continue the wedge lines
Sphynx Key Markers
- Hairless body covered in fine peach-fuzz down — skin feels warm and soft like chamois leather or suede
- Wedge-shaped head with prominent cheekbones and a visible whisker break
- Oversized, wide-set ears with rounded tips, set high on the head — described as "bat-like" in the CFA standard
Temperament & Personality
Peterbald
- Affectionate and people-oriented — follows owners, greets at the door, and wants to be part of everything
- Intelligent and curious — learns tricks, opens doors, and solves puzzle feeders
- Active and playful — enjoys interactive toys and climbing; stays kittenish into adulthood
- Dog-like loyalty — forms deep bonds and often walks on a leash
- Social with strangers, children, and other pets — rarely shy or territorial
- Heat-seeking — bare skin offers no insulation; Peterbalds want warm spots, sweaters, and laps
Sphynx
- Intensely people-oriented — follows owners around the house, sleeps under the covers, greets at the door
- Highly energetic and playful — climbs, jumps, and invents games; needs interactive toys and cat trees
- Dog-like loyalty — learns tricks, walks on a leash, and comes when called
- Warmth-seeking — drawn to heat sources, sunny spots, blankets, and human laps
- Social with strangers, children, and other pets — rarely shy or skittish
- Vocal but not noisy — communicates with chirps, trills, and meows to express needs and moods
Health Notes
Peterbald
- Progressive retinal atrophy (PRA) — a genetic eye disease documented in the breed that causes slow vision loss; DNA testing available and recommended before breeding
- Skin care needs — without hair, skin oils build up into greasy film, acne, and yeast issues; regular gentle bathing is necessary
- Sunburn and temperature intolerance — bare skin sunburns easily and offers no warmth; an indoor-only lifestyle with pet-safe sunscreen near windows
- Dental disease — some lines are prone to tooth issues; regular brushing and annual cleanings recommended
- Generally robust — beyond PRA screening and skincare, no breed-specific diseases are documented
Sphynx
- Hypertrophic cardiomyopathy (HCM) — Sphynx cats have one of the highest HCM rates among all breeds (estimated 14–40%); regular echocardiogram screening recommended by veterinary cardiologists
- Congenital myasthenic syndrome (CMS) — a genetic neuromuscular disorder causing generalized muscle weakness, head-bobbing, and easy fatigue in kittens; DNA test available through UC Davis VGL
- Urticaria pigmentosa — a skin condition causing raised, crusty lesions from mast cell accumulation under the skin; more common in Sphynx than any other breed
- Juvenile-onset periodontal disease — the lack of fur does not protect the mouth; Sphynx cats frequently develop gingivitis and tooth resorption by early adulthood
- Skin oil buildup and yeast infections — without fur to absorb oils, the skin requires weekly bathing to prevent greasy buildup, acne, and Malassezia yeast overgrowth
- Sun sensitivity and temperature intolerance — the absence of fur means Sphynx cats sunburn easily and cannot tolerate cold; strictly indoor lifestyle recommended

Breed Profiles & More Comparisons
Peterbald
A hairless, or nearly hairless, cat from St. Petersburg, Russia, with the long wedge head and svelte body of an Oriental Shorthair. Peterbalds come in five coat types, from completely bald to a regular short coat, and a single litter can contain several. Affectionate, intelligent, and intensely attached to their people, they need warmth and regular skincare.
Sphynx
A hairless cat with a warm suede-like skin, oversized bat ears, and a personality that demands your attention. Sphynx cats are intensely social, dog-like in their loyalty, and need human company more than most breeds.
