Breed Histories
Sphynx Origins
The Sphynx breed originated from a spontaneous genetic mutation in Toronto, Canada, in 1966. A domestic shorthair gave birth to a hairless kitten named Prune. Breeders recognized the potential of this recessive gene and, through careful outcrossing, developed the breed we know today. Most Sphynx cats possess a fine, suede-like down rather than being completely hairless.
Devon Rex Origins
The Devon Rex began in 1960 with Kirlee, a stray cat in Devon, England, who possessed an unusual curly coat and large ears. Genetic testing confirmed that the Devon Rex's curl is caused by a different recessive gene than the Cornish Rex. Selective breeding preserved these distinctive "pixie" traits.
Physical Characteristics
Coat and Skin
- Sphynx: Features fine downy fuzz or skin that feels like a warm, suede-like peach. They produce significant skin oils, requiring regular cleaning.
- Devon Rex: Has short, soft, and distinctly wavy or curly fur. The texture is velvety, often with sparse guard hairs.

Temperament and Personality
Sphynx Personality: The "Velcro" Cat
Sphynx cats are legendary for their devotion. They are often called Velcro cats because they desire constant physical contact. Expect an energetic companion who follows you from room to room and seeks out warm laps.
- Affection Level: Extreme
- Activity Level: High
Devon Rex Personality: The Social Pixie
The Devon Rex retains a kitten-like curiosity throughout its life. Highly intelligent, they enjoy learning tricks and "helping" with household tasks. They are agile and can be mischievously inventive. Explore more about these unique cat breeds in our detailed overview.

- Activity Level: Very High
Special Care Requirements
Sphynx Skin Care (High Maintenance)
Because they lack fur to absorb body oils, skincare is essential:
- Weekly Bathing: Use a gentle, pH-balanced shampoo to remove oil buildup.
- Ear Cleaning: Large ears accumulate wax quickly and need weekly attention.
- Warmth: They require heated beds and sweaters when temperatures drop.
Devon Rex Coat Care (Low Maintenance)
Grooming for a Devon Rex is minimal. For those seeking a breed guide & comparison, maintenance is a key factor:
- Minimal Brushing: Use a soft brush occasionally; over-brushing can damage delicate curls.
- Ear Checks: Their large ears still require regular cleaning to prevent infection.
- Active Play: They need vertical space like cat trees to satisfy their climbing instincts.
Health Considerations
Both breeds should be screened with regular echocardiography for Hypertrophic Cardiomyopathy (HCM), the most common heart disease of domestic cats. Sphynx are explicitly listed among the breeds in which HCM is more prevalent, and a peer-reviewed 2012 cardiology study of 114 Sphynx found roughly one in five affected by HCM and about one in three showing some form of structural heart disease — with males often developing disease earlier than females (Cornell Feline Health Center — Hypertrophic Cardiomyopathy; Sphynx cat — Hypertrophic cardiomyopathy, Wikipedia). Because the prevalence of genetic heart disease in Sphynx is high, many breeders recommend yearly cardiac screening.
Because Sphynx lack the fur that normally absorbs skin oils, they produce excess sebum that can build into a sticky brown layer and predispose them to bacterial skin infections; their exposed skin is also vulnerable to sunburn and skin cancer with prolonged sun exposure (Sphynx cat — Care, Wikipedia). The Cat Fanciers' Association lists hypertrophic cardiomyopathy, hereditary myopathy, urticaria pigmentosa, and periodontal disease as the breed-specific concerns responsible breeders screen for (CFA Sphynx breed profile).
Devon Rex share the hereditary myopathy risk — a COLQ-related congenital myasthenic syndrome documented in both breeds — and are additionally predisposed to feline atopic dermatitis and Malassezia dermatitis. CFA also highlights the high incidence of type B blood in the gene pool, which can cause fatal neonatal isoerythrolysis if a type B queen is bred to a type A tom (Devon Rex — Health, Wikipedia; CFA Devon Rex breed profile).
Cost of Ownership
The Sphynx is generally the more expensive of the two to buy, typically falling in the $1,800–$3,500 range for a pet-quality kitten from a reputable U.S. breeder in 2025–2026 — though figures vary widely by region, bloodline, and whether the cat is show or pet quality — plus higher annual costs for specialized skincare, ear care, and heating. CFA notes that Sphynx are "among the higher-priced cat breeds" and that reputable-breeder kitten waiting lists are common (CFA Sphynx breed profile). The Devon Rex is often more affordable initially, typically $1,000–$2,000 in recent years (regional pricing and retired adults vary), and has lower routine grooming expenses; CFA cautions that locating a kitten from a reputable breeder can still take time (CFA Devon Rex breed profile).
