Devon Rex

By Sophie Kininmonth · 23 Nov 2025 (updated 21 Jul 2026) ·6 min read

The Devon Rex is a small-to-medium cat best known for its short, rippled coat and outsized, low-set ears, a combination that gives it a genuinely distinctive look. It is a bright, people-focused breed that tends to follow the household from room to room rather than watch from a distance, which is a big part of the appeal. The coat is soft and low-shedding, and grooming is often lighter than people expect. It is also a cat with a few practical quirks worth knowing before you commit: the coat insulates poorly, so these cats seek out warmth, and there are a couple of breed-linked health conditions worth screening for. None of that is a dealbreaker, but it is worth understanding first. ^{1, 2}

Devon Rex at a glance

Origin: Devon, England (a curly-coated kitten called Kirlee, born in 1960). ²
Build: Small to medium, typically around 2.7 to 4.1 kg, with males often heavier. ²
Coat: Short, soft and wavy or curly, with little guard hair and a delicate texture. ²
Colours and patterns: All colours and patterns are recognised. ²
Temperament: Curious, active and people-oriented, usually happiest with company and regular interaction. ^{1, 2}

History and Origin

The breed traces back to a single curly-coated kitten born in Buckfastleigh, Devon, in 1960. The kitten, named Kirlee, was first thought to carry the same "rex" coat mutation as the Cornish Rex. Breeding trials proved otherwise. The Devon and Cornish coat mutations turned out to be different, and the Devon Rex line was developed separately from Kirlee's descendants. ²

Appearance and Physical Characteristics

A Devon Rex looks like it was drawn with the features turned up: very large, low-set ears, big oval eyes, high cheekbones and a short muzzle. The body is compact and muscular, with a longish neck and a tapering tail. ²

The coat is where the breed earns its name. It is short, soft and rippled, with little guard hair, which can make it feel like suede or velvet. The curl can be uneven, and some cats carry thinner patches, especially as kittens moult and the adult coat comes in. ²

Temperament and Personality

Devon Rex cats move through the house like small, warm-bodied scouts, perching high, investigating open doors and inserting themselves into whatever is happening. They are commonly described as intelligent, playful and very people-focused, and they often prefer to stay close rather than drift off alone. ^{1, 2}

Many are chatty in their own way, more chirps and running commentary than constant yelling. They generally do best with daily play and something to climb, chase and puzzle over. Boredom can turn into mischief, especially in young cats. ¹

Is a Devon Rex Right for You?

This is a cat for households that want to be involved with their pet. A Devon Rex tends to follow the day rather than watch it from across the room, and it does best where someone is around and willing to play. If you want an independent, low-contact cat, this is not the obvious pick. ^{1, 2}

Practical fit matters too. The coat insulates poorly, so a cold, draughty home is not ideal without warm sleeping spots provided. And because there are known inherited conditions in the breed, choosing a breeder who screens for them should be part of your decision rather than an afterthought. ¹

Care and Housing

Devon Rex cats often feel warmer to the touch. That is not because their body temperature is higher, it is because their coat provides less insulation. In cooler weather they will seek out heat: sunny windows, warm bedding and human laps. Provide warm sleeping spots and keep them away from cold draughts. ^{1, 2}

Beyond warmth, the routine care is much like any cat:

Ears: Large ears can collect oily build-up, so check them regularly and clean only as needed with a vet-recommended ear cleaner. ¹
Nails: Regular trims help prevent overgrowth and snagging. ¹
Teeth: Home dental care with pet toothpaste, plus routine vet checks, helps reduce dental disease risk, as with any cat. ¹

Training and Exercise

Devon Rex cats are typically active jumpers and quick learners. Short daily play sessions suit them better than one long, exhausting burst, so wand toys, chase games and puzzle feeders all help burn energy while keeping the mind busy. ¹

Positive reinforcement (treats, pats, a favourite toy) works well for simple behaviours like coming when called, tolerating nail trims, or stepping into a carrier without a wrestling match.

Health and Lifespan

The Devon Rex is generally described as a healthy breed, but like most pedigree cats it has known inherited conditions worth discussing with a vet and a responsible breeder. ¹

Hypertrophic cardiomyopathy (HCM): Some lines can be affected. Many breed bodies recommend screening breeding cats with cardiac ultrasound (echocardiography) performed by a suitably qualified veterinarian. ¹
Devon Rex congenital myasthenic syndrome (CMS), also called hereditary myopathy: This inherited muscle-weakness condition has a DNA test available (it is autosomal recessive). Responsible breeding uses genetic testing to avoid producing affected kittens. ⁴

Other issues can occur in individual cats, as they can in any breed, so the practical baseline stays the same: routine check-ups, and prompt investigation of any breathing difficulty, exercise intolerance, weakness or unexplained weight loss. ⁵

Grooming and Care

The Devon Rex is usually easier to groom than long-haired breeds, but low maintenance does not mean no maintenance. The coat hair is delicate, and heavy brushing can break it, so gentle handling matters. ²

Groom gently: In many cases a light hand-stroke or very soft grooming is enough to remove loose hair and spread skin oils without damaging the coat. ^{1, 2}
Bathing: Some Devons develop a slightly greasy feel because the coat has fewer guard hairs. Occasional bathing with a cat-safe shampoo may help, but frequent bathing can irritate the skin and damage the curls. If you are unsure, ask your vet what suits your cat's skin. ³

Finding a Devon Rex

If you are set on a Devon Rex, start with adoption and breed-specific rescue where possible, then widen your search to registered breeders who can show clear health practices. ^{6, 7}

Never buy sight unseen: meet the kitten, and ideally the mother, and see the conditions they are raised in. ^{6, 7}
Ask about screening: at a minimum, discuss HCM screening of the parents and genetic testing for Devon CMS or myopathy in the breeding lines. ^{1, 4}
Watch for red flags: pressure to pay deposits immediately, "delivery only", vague medical history, or reluctance to let you visit. ⁶

A Few Things Worth Knowing

They are not hypoallergenic. No cat truly is. Devon Rex cats may shed less noticeably, and some people with allergies find them easier to tolerate, but they still produce allergens. If allergies are a concern, spend time with the breed before committing. ¹
Grooming is light, not zero. The coat can be fragile, and the ears may need checking for oily build-up more often than you would expect. ^{1, 2}
They feel the cold. The coat insulates poorly, so warm bedding and a draught-free sleeping area make a noticeable difference. Most will seek out warm spots on their own. ^{1, 2}

The Bottom Line

A Devon Rex suits a household that likes an involved, active cat, one that follows the day rather than watching from a distance. Keep it warm, keep play interesting, groom softly, and take health screening seriously when choosing a breeder. In return you get a small, bright companion with a coat that looks like wind over grass. ^{1, 2}
