The Devon Rex Cat Breed Guide
Welcome to our Devon Rex cat breed guide. The Devon Rex is the cat that looks like it arrived from another dimension entirely — enormous ears, huge luminous eyes, a pixie face, and a soft curly coat that invites touching and refuses to let go. Often compared to an elf, a gremlin, or even Yoda (urban legend suggests Steven Spielberg's Devon Rex influenced the famous character's design), the Devon Rex is one of the most distinctive-looking cats in the world.
But looks alone do not explain the devoted following this breed inspires — it is their extraordinary personality that truly captures hearts.
Appearance & Coat
The Devon Rex is a medium-sized cat with a lean, athletic body, long slender legs, and a naturally high-waisted appearance that gives them a slightly otherworldly silhouette. Despite looking delicate, they are surprisingly muscular and agile — enthusiastic jumpers who treat vertical space as their natural territory. The tail is long, slim, and tapered. The paws are small and oval.
The head is the breed's most dramatic feature — triangular in shape, with dramatically high cheekbones, a short muzzle, a strong chin, and the breed's most recognisable trademark: enormous, wide-set ears with a broad base that protrudes both to the side and backward, giving them an unmistakable elfin or bat-like appearance. The eyes are very large, oval, and slightly slanted toward the outer edges of the ears — wide-set and brilliantly expressive in any colour. Even the whiskers and eyebrows are curly, though they are fragile and often short or broken.
The coat is soft, wavy, and distinctively curly — produced by a genetic mutation entirely different from the Cornish Rex. Devon Rex cats have all three types of cat hair — guard hair, awn hair, and down — but the guard hair is short and rexed (curled), producing the characteristic rippled, plush texture. The coat is recognised in every colour and pattern. It sheds minimally compared to most breeds, and some allergy sufferers find the Devon Rex more manageable than other cats — though no cat is truly hypoallergenic as allergens are present in saliva and dander regardless of coat type.
Purrsonality & Temperament
The Devon Rex is a breed of exceptional warmth, sociability, and mischief — often described as "a monkey in a cat suit" or "part cat, part dog, part child," and all of these comparisons capture something true. These are intensely people-oriented cats who want to be involved in absolutely everything and have a remarkable talent for making their presence felt.
They are affectionate in a whole-body, enthusiastic way — climbing onto shoulders, burrowing under blankets, draping themselves across laps, and generally making it clear that they find humans irresistible. They are also deeply sensitive to human mood and emotion, attuned to their people in a way that makes them genuinely comforting companions. They form strong bonds with their entire family and are welcoming to children, other cats, and dog-friendly dogs — their confidence and sociability means they rarely struggle with introductions. Their vocalisation is moderate and conversational rather than demanding — they will tell you what they think, but they are not persistent about it.
Behaviours & Characteristics
The Devon Rex is a high-energy, high-curiosity breed who approaches life with boundless enthusiasm and a comedic flair that is entirely their own. They are acrobatic jumpers who will colonise every elevated surface in the home — shelves, tops of wardrobes, refrigerators — and they treat the ceiling as a goal rather than a ceiling. TICA's nickname for them — "imp in a cat suit" — captures the spirit perfectly.
They are highly intelligent, food-motivated, and remarkably trainable — they can learn to play fetch, respond to commands, and even, reportedly, use a standard toilet. Puzzle feeders and interactive toys are enthusiastically received. Their hunting instincts are sharp and focused — wand toys and feather teasers bring out a fast, precise athleticism that their slight frame does not suggest. Like the Cornish Rex, they are heat-seekers who will locate the warmest spot in any room and claim it immediately — under blankets, in sunny patches, or pressed against a warm human. A bored Devon Rex will find their own entertainment, and this is rarely quiet.
Living With A Devon Rex
Living with a Devon Rex is an immersive, energetic, deeply affectionate experience — and it is not well-suited to owners who prefer a more independent, low-key cat. The Devon Rex needs human company, daily engagement, and regular interaction, and they are genuinely prone to loneliness and anxiety if left alone for long periods. A second cat is strongly recommended for households where people work full time.
They are excellent with children and social households — their confidence and enthusiasm mean they thrive where there is plenty going on. They adapt well to flat and house living provided they have enough vertical space and enrichment. They are strictly indoor cats — their minimal coat offers almost no protection from cold weather or UV radiation, and outdoor exposure brings genuine health risks. Their exposed skin can accumulate oils without the protection of a full guard coat, requiring occasional gentle bathing. Their very large ears also accumulate wax readily and benefit from regular gentle cleaning. They are not hypoallergenic but are among the lower-shedding breeds.
Health & Grooming
The Devon Rex is generally a healthy breed with a lifespan of 12 to 15 years, though some individuals live considerably longer. Despite descending from a relatively limited gene pool — all Devon Rex trace their ancestry back to the original curly-coated Kirlee — they have remained reasonably robust. There are, however, several hereditary conditions prospective owners should ask breeders about.
Hypertrophic Cardiomyopathy (HCM) is the most common concern — the most prevalent heart disease in cats — causing thickening of the heart muscle. It can be silent in its early stages, and regular cardiac screening via echocardiogram is recommended from middle age onwards. Hereditary Myopathy (Devon Rex Myopathy or Spasticity) is a breed-specific inherited muscle weakness condition affecting the head and neck muscles, typically appearing in kittens between three weeks and six months of age. Genetic testing is available and responsible breeders screen for it. Patellar Luxation — the kneecap slipping out of its groove — is also a known concern, with mild cases managed by joint supplements and more severe cases requiring surgery. Skin sensitivity is worth monitoring — the exposed skin can develop seborrhea (oily or flaky skin), and the large ears are prone to wax build-up and infection.
Grooming the Devon Rex requires a gentle touch — the curly coat is fragile and should never be brushed, as this can damage or break the delicate hairs. A gentle wipe with a soft damp cloth or chamois is the correct approach, keeping the coat clean without disturbing the curl structure. Occasional baths — every few weeks to once a month — help manage skin oil build-up. The large ears need regular gentle cleaning. Nail trims and dental care round out the routine.
Breed Origins
The Devon Rex was born from a single spontaneous genetic mutation discovered in Devon, England, in 1959 or 1960 — accounts vary slightly on the exact year. A domestic cat owned by Beryl Cox of Buckfastleigh, Devon, gave birth to a litter that included one extraordinary male kitten with a tightly curled coat, enormous ears, and a distinctly pixie-like face. Cox named him Kirlee.
Cox was aware of the Cornish Rex — which had emerged from a similar curly coat mutation in Cornwall a decade earlier — and assumed Kirlee was related. When Kirlee was crossed with Cornish Rex females, however, the litters produced only straight-haired kittens, proving conclusively that the two mutations were genetically distinct. Kirlee was confirmed as the foundation of an entirely new breed, and a careful breeding programme was developed using a wider range of domestic cats to build a healthy gene pool. The Devon Rex was granted CFA recognition in 1979.
It is worth noting that the Devon Rex and Cornish Rex, despite their similar appearance and names, cannot be cross-bred to produce curly-coated kittens — their coat mutations are produced by completely different recessive genes on different chromosomes. Every Devon Rex in the world today traces its ancestry back to Kirlee.
Dietary Needs
The Devon Rex is an obligate carnivore and thrives on a high-quality diet built around named animal protein — chicken, turkey, or fish — as the primary ingredient. Their active, energetic lifestyle means they have a healthy appetite and generally maintain weight well — but given that obesity places additional strain on both joints and heart, portion control remains important throughout their life.
Multiple smaller meals throughout the day suit the Devon Rex's energetic metabolism well. A combination of wet and dry food works effectively — wet food supports hydration and kidney health, while quality dry food can assist with dental health, which is a concern in this breed. Taurine — an essential amino acid found in quality animal-based cat foods — is particularly important for heart health given the breed's HCM predisposition. Avoid high-carbohydrate foods and grain-heavy fillers. The Devon Rex is famously food-motivated and will attempt to steal from plates, investigate anything edible, and apply considerable charm to the task of obtaining additional treats — portion discipline is essential. Fresh water should always be freely available.
In Summary:
The Devon Rex is a breed for those who want a genuine companion — a cat who is truly, enthusiastically present in their life every single day. Funny, warm, acrobatic, mischievous, and deeply loving, they are the kind of cat that fills a home with life and leaves a permanent mark on everyone who knows them. They are not for everyone — they need engagement, company, and warmth — but for the right owner, the Devon Rex is one of the most joyful, rewarding, and utterly unforgettable cats in the world.
