Overview
Both the Sphynx and the Devon Rex are highly social, affectionate breeds with unique looks and devoted followings. Neither is truly "hypoallergenic," but both can be easier for some allergy sufferers because of reduced shedding (Sphynx) or very sparse, short curls (Devon Rex). Your choice should hinge on how much grooming and temperature management you can provide, the activity level you want, and the specific health screening you’ll pursue.

Temperament (side-by-side)
Sphynx
- Extremely people-oriented and attention-seeking; often described as "dog-like."
- Thrive on companionship; can develop separation anxiety if left alone many hours.
- Social with strangers and other pets when properly socialized.
- Playful, mischievous and highly curious; retains kitten-like energy well into adulthood.
- Affectionate but slightly less demanding of constant lap time than Sphynx.
- Good with families and other pets; loves interactive games and agility-style play.
Exercise & Activity (side-by-side)
Sphynx
- Activity level: Moderate to high; enjoy interactive play and climbing.
- Recommended play time: about 20–40 minutes/day of active engagement (short sessions 2–3× daily).
- Activity level: High; very energetic and acrobatic.
- Recommended play time: about 30–60 minutes/day, broken into sessions; they enjoy fetch, puzzle toys and vertical spaces.
Grooming & Skin Care (side-by-side)
Sphynx
- Coat: Essentially hairless but with a fine down that holds skin oils.
- Bathing: Regular bathing is required to remove oil and prevent skin greasiness — typically every 1–2 weeks (many owners bathe once weekly).
- Ears & nails: Ears produce more wax and need weekly cleaning; nail trims weekly.
- Sun & skincare: Susceptible to sunburn and environmental irritants. Use pet-safe sunscreen or limit sun exposure.
- Coat: Short, soft, curly coat that sheds very little.
- Bathing: Less frequent bathing than Sphynx — often monthly or only as needed.
- Brushing: Gentle brushing or grooming once weekly removes dead hairs and keeps curls healthy.
- Ears & nails: Ears may be large and waxy; check weekly. Nail trims weekly.
- Sphynx: Bath 1×/week, ear clean weekly, nails weekly.
- Devon Rex: Brush 1×/week, bath monthly or as needed, ear check weekly.
Temperature Sensitivity & Home Environment
Sphynx
- Very temperature-sensitive due to lack of insulating fur. They seek out warm spots (sun patches, laps, heated beds).
- Should live strictly indoors (risk of sunburn, hypothermia, skin injuries outdoors).
- In cooler climates, owners often use sweaters or heating pads (with safety measures).
- Also appreciates warmth and often loves to nestle in blankets or lap-sit, but their curly coat provides more insulation than a Sphynx.
- More tolerant of cooler indoor temperatures than a Sphynx but still prefers a cozy home.
Health & Genetic Risks (side-by-side)
General note: Reputable breeders perform health screening; both breeds have breed-specific predispositions. Regular vet care, early screening and genetic testing where available reduce risks.
Sphynx
- Known predisposition to hypertrophic cardiomyopathy (HCM); breeding programs often screen for HCM with echocardiography.
- Skin conditions: acne, fungal infections, and sunburn are possible; owners must maintain skin care.
- Other issues: dental disease and occasional respiratory sensitivity.
- Also reported cases of HCM in the breed; breeders increasingly screen lines.
- Patellar luxation (kneecap issues) and some congenital muscular conditions have been reported in lineages; reputable breeders screen hips/knees and observe kittens for muscle dysfunction.
- Skin/ear sensitivity: their large ears and short coat make ear care and skin checks important.
- Cardiac: Echocardiogram and cardiac exams (every 1–2 years as recommended by your vet/breeder) for both breeds.
- Genetic testing: Ask breeders for results of breed-specific tests where available.
- Routine: Dental care, parasite prevention, and attention to dermatologic problems are important for both.
Hypoallergenic Qualities
Short answer: No cat is truly hypoallergenic.
Why: Most cat allergy reactions are to Fel d 1, a protein in saliva and sebaceous oils, not to the presence of fur itself. That means even hairless cats produce allergy-causing proteins. (American College of Allergy, Asthma & Immunology — ACAAI)
How Sphynx and Devon Rex compare
- Sphynx: Lack of fur reduces airborne dander and loose hair, which can lower allergen spread in some households — but Sphynx still produce Fel d 1 in their skin oils and saliva. Frequent bathing reduces oily residue and can reduce allergen levels.
- Devon Rex: Minimal shedding and short, curly coat mean fewer loose hairs and dander compared with many breeds. Some allergy sufferers report better tolerance with Devon Rex.
- Spend time with individual kittens/adults before adoption to test reactions.
- Regular bathing (especially for Sphynx), HEPA air purifiers, strict vacuuming, and limiting cat access to bedrooms reduce allergen exposure.
- Consult an allergist; some people tolerate these breeds while others do not.
Cost Considerations
Upfront
- Kitten price: Sphynx tends to be pricier on average (roughly $1,200–$3,000+ depending on lineage, registration, and location). Devon Rex kittens commonly range $800–$2,000.
- Food, routine vet care, vaccinations, spay/neuter, microchip: comparable for both breeds.
- Additional costs for Sphynx: frequent bathing supplies, more frequent dermatologic care, and higher heating/comfort costs in cool climates.
- Insurance: Consider pet insurance for hereditary conditions (cardiac screening may be costly if problems arise).
Which Breed Is Right For You?
Consider these lifestyle scenarios to help decide:
- You want a constant companion, love warm laps, and don’t mind weekly baths: Sphynx may be your match. Ideal for someone home often or who works from home and can keep the cat warm and attended.
- You want a playful, high-energy cat that performs tricks, loves fetch, and will entertain kids: Devon Rex is a strong fit. Good for families and active homes with interactive play time.
- You have mild cat allergies and want to minimize dander: Try both breeds with an in-person allergy test. Many allergy sufferers tolerate Devon Rex or Sphynx better, but neither guarantees no reaction.
- You live in a cold climate and can’t maintain a consistently warm indoor environment: Devon Rex will be easier to keep comfortable than a Sphynx.
- You want a lower-maintenance coat routine: Devon Rex requires less frequent bathing and generally simpler skin care.
- You’re prepared to invest in cardiac screening and a trusted breeder: Both breeds require careful breeder selection to reduce inherited disease risk.

- Devon Rex are highly energetic, playful and lower-maintenance for bathing, though they still need weekly grooming and attention.
- Both breeds benefit from responsible breeders who perform cardiac screening (HCM) and other health checks; ask to see health clearances.
- Match the breed to your daily schedule, tolerance for grooming & temperature management, and willingness to pursue regular vet screening.
If you’d like, I can:
- Provide a short checklist to use when screening breeders for either breed.
- Help you find local breed rescues and adoption resources.
Frequently Asked Questions
Are Sphynx or Devon Rex hypoallergenic?
No cat is truly hypoallergenic. Both breeds may be better tolerated by some allergy sufferers because Sphynx have very little hair and Devon Rex shed minimally, but both produce the Fel d 1 protein that causes most cat allergies. Try time with individual cats and consult an allergist before adopting.
How often should I bathe a Sphynx?
Most Sphynx benefit from bathing about once a week to every two weeks to remove excess skin oils and prevent buildup. Ear cleaning and nail trims should be checked weekly as well.
Which breed is better for families with kids?
Both breeds are generally good with families. Devon Rexes are highly playful and often do well with children. Sphynx are affectionate and social but may prefer gentler handling — supervise interactions and teach kids respectful petting.
Do both breeds need special health screening?
Yes. Both breeds have reported cases of hypertrophic cardiomyopathy (HCM). Reputable breeders will offer cardiac screening (echocardiograms) and other relevant checks. Ask to see health clearances before purchase or adoption.
