Devon Rex cats are lively, people-focused companions with a short, wavy coat and striking oversized ears. They are not hypoallergenic, and their social nature means they generally suit homes that can offer daily interaction. Before choosing one, plan for routine ear, claw, and dental care—and ask a breeder for health-screening records.

Where the Devon Rex comes from

The Devon Rex originated in Buckfastleigh, Devon, England. The breed’s story begins with Kirlee, a curly-coated male kitten kept by Beryl Cox in 1960. Breeders initially wondered whether his coat came from the same mutation as the Cornish Rex, but the mutations are distinct, and the breeds developed different coat characteristics. TICA’s Devon Rex profile and the TICA breed introduction recount the history.

What does a Devon Rex look like?

A Devon Rex is a small-to-medium, muscular cat with a short, soft, wavy coat, large low-set ears, prominent cheekbones, a short muzzle, and large eyes. TICA lists females at 5–7 lb and males at 7–9 lb in its current breed profile; these are profile figures, not a promise about an individual cat. Coat curl and density vary, and some Devons have thin or nearly bare-looking patches. A kitten’s coat may also change as it matures.

Devon Rex and Cornish Rex are not the same breed

Both breeds have Rex-type coats, but their coat mutations are different. Appearance and texture vary among individuals, so a curly coat alone does not make the breeds interchangeable. Neither breed should be assumed to be allergy-safe.

What is a Devon Rex cat like?

Devons are typically active, curious, intelligent, playful, and strongly oriented toward people. They may follow people around, seek attention, climb, and jump to high places. Interactive play and puzzle toys can help keep an energetic cat engaged. These are breed tendencies, not guarantees of an individual cat’s behavior.

Time and company are important considerations. TICA cautions that Devons can become bored if left alone for long periods, which may lead to mischief or destructive behavior. A Devon is more likely to fit well in a home prepared to provide daily interaction, play, and safe places to climb. Some do well with children, other cats, or cat-friendly dogs, provided introductions are gradual and each animal’s needs and boundaries are respected.

How long do Devon Rex cats live?

Published breed-profile estimates put the Devon Rex lifespan at roughly 13 to 17 or more years: TICA lists 14–17+ years, while Zoetis Petcare lists 13–17 years. These are estimates rather than a guarantee; an individual cat’s lifespan depends on factors including health, environment, and veterinary care. TICA’s profile and Zoetis Petcare’s Devon Rex overview provide the published ranges.

How do you care for a Devon Rex?

Coat, ears, claws, and teeth

The short coat usually needs little grooming; for many cats, a gentle hand stroke is enough. Avoid assuming that every Devon’s coat is identical or needs no attention at all. Check the large ears and clean them when they look dirty, following your veterinarian’s advice on safe technique. TICA recommends weekly claw trims and regular tooth brushing with veterinarian-approved pet toothpaste. A suitable scratching surface also helps support normal scratching behavior. TICA’s care guidance covers these routines.

Play, space, and companionship

Offer daily play, interactive or puzzle toys, and secure elevated spots such as a sturdy cat tree or tall scratching post. Supervise access to high places and keep windows, balconies, and other hazards secure. If your household is away for much of the day, consider how you will provide company and enrichment rather than assuming the cat will be content alone.

Food and water

Provide fresh water and choose food and portions with your veterinarian based on the cat’s age, health, and body condition. A breed profile cannot establish the right calorie intake or feeding schedule for an individual cat.

Are Devon Rex cats hypoallergenic?

No. A Devon Rex’s short, relatively low-shedding coat does not mean the cat is hypoallergenic. The Cat Fanciers’ Association says Devons shed less than many breeds but are not hypoallergenic; TICA likewise notes that they produce allergens like other cats and that reactions vary by person and cat. If allergies are a concern, spend time with the specific cat before committing and consider medical advice. An exposure visit cannot guarantee you will remain symptom-free. TICA’s breed introduction and CFA’s Devon Rex profile discuss the allergy concern.

What health problems should owners know about?

TICA characterizes the breed as overall healthy while recommending attention to available genetic markers, including Devon myopathy, and screening parent cats for hypertrophic cardiomyopathy (HCM). CFA also highlights blood type: type B is common in the Devon Rex gene pool, and incompatible parental blood types can create a risk of neonatal isoerythrolysis, a condition that can endanger or kill kittens without appropriate early care. These are breeding and screening concerns, not evidence that a particular Devon has a condition.

Zoetis Petcare lists endocrine or metabolic disorders, neurological abnormalities, skin and coat conditions, heart disease, and bone and joint problems as categories to know about. It does not provide incidence rates or diagnostic criteria for these categories, so they should not be read as quantified risks or diagnoses. A veterinarian can assess symptoms and recommend care for an individual cat. Breed information does not replace veterinary advice.

Questions to ask a Devon Rex breeder

Ask for clear answers and supporting records, not just verbal assurances. A responsible discussion should cover the kitten’s health and socialization as well as screening of its parents.

  • Which available genetic tests have been completed, including testing for Devon myopathy? May I see the results?
  • Have the parent cats been scanned for HCM? When was each scan performed, and can I review the documentation?
  • What are the parents’ blood types, and how does the breeder manage blood-type incompatibility risks for kittens?
  • What veterinary care, health records, and socialization will the kitten have received before going home?
  • What ongoing checkups or screening does the breeder recommend discussing with my veterinarian?

Ask your veterinarian to help interpret records and plan ongoing care; a screening result is not a substitute for an individual clinical assessment. TICA’s breed care guidance and CFA’s Devon Rex profile discuss testing and blood-type considerations.

Is a Devon Rex right for your home?

A Devon Rex may suit you if you want an involved, playful companion and can provide regular company, enrichment, and routine care. Think carefully before choosing one if the cat would be alone for long stretches or if allergies are a concern; the breed label cannot predict your reaction. Meet the individual cat, review health records, and discuss your plans with a veterinarian before bringing one home.
