Quick Comparison
Visual Differences
Telling a Devon Rex from a Sphynx
Sphynx are hairless (covered in fine peach-fuzz down only) with a wedge-shaped head, lemon-shaped eyes, and a warm suede-like skin texture. Devon Rex have a full short wavy coat — they are NOT hairless. Sphynx also have thicker paw pads and a rounder, barrel-chested torso.
Telling a Sphynx from a Devon Rex
Devon Rex cats have a short, wavy coat of soft curls — they are not hairless. Their head is shorter and more heart-shaped with a distinct pixie look, while the Sphynx has a longer wedge-shaped head and complete or near-complete hairlessness.
Devon Rex Key Markers
- Large, bat-like ears set wide and low on the head — broad at the base with rounded tips and minimal inner fuzz; the most distinguishing feature of the breed, giving the face its characteristic pixie expression
- Short, soft, wavy coat with a distinct marcel wave pattern — the waves are most prominent on the back and sides; the coat is fine and delicate, with some Devon Rex cats having bald patches, especially on the top of the head and neck
- Short wedge-shaped head with prominent cheekbones, a short muzzle, and a defined whisker break — the CFA standard calls it a pixie face with a gentle curve from forehead to nose; the whiskers are crinkly and short
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
Devon Rex
- Extremely people-oriented — wants to be involved in everything you do, follows from room to room, and sits on your shoulder or keyboard given the chance
- Mischievous and playful — opens cabinets, steals small objects, and invents games; stays kittenish well into senior years
- Excellent jumper — routinely reaches the highest perches in the house and watches household activity from above
- Social with strangers, children, and other pets — rarely shy or territorial, greets visitors at the door like a dog
- Moderate vocalization — chirps and trills rather than yowling, but will voice displeasure at closed doors
- Heat-seeking — the short, fine coat offers little insulation, so Devon Rex cats gravitate toward warm spots, sweaters, and under the covers
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
Devon Rex
- Hypertrophic cardiomyopathy (HCM) — genetic heart disease affecting Devon Rex; echocardiogram screening recommended for breeding cats
- Congenital myasthenic syndrome (CMS) — a neuromuscular disorder causing generalized muscle weakness, head-bobbing, and easy fatigue in kittens; DNA test available through UC Davis VGL
- Patellar luxation — kneecap dislocation more common in Devon Rex than many breeds, likely due to fine-boned hind legs
- Skin sensitivity and dermatitis — the delicate single coat offers minimal skin protection; avoid harsh grooming brushes and over-bathing
- Dental disease — the narrow muzzle shape contributes to tooth crowding and gingivitis risk; regular dental care particularly important
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
Devon Rex
A pixie-faced cat with oversized bat ears and a short wavy coat that feels like soft lamb’s wool. Mischievous, people-oriented, and endlessly energetic — the breed was discovered in Devon, England in 1960 when a stray cat gave birth to a curly-coated kitten.
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.
