Devon Rex: the pixie-faced cat that acts more like a monkey than a feline

In 1959, near an abandoned tin mine in Buckfastleigh, Devon, in southwest England, a woman named Beryl Cox took in a litter of feral kittens. One of them had a curly coat that looked, at first glance, like the Cornish Rex discovered just nine years earlier in the next county over. Cox bred that curly tom to a Cornish Rex female, expecting to reinforce the curl. Instead the entire litter came out straight-coated. Geneticists eventually confirmed why: the two curly breeds carry separate, non-allelic mutations in the same KRT71 gene. Two independent breeds that arrive at a similar coat by different genetic roads.

The original mine cat, named Kirlee, became the founding sire of the Devon Rex. The breed stabilized through the 1960s and was recognized internationally as distinct from the Cornish Rex by 1967. Today it is one of the most instantly recognizable cats in the registry thanks to its elfin look: a small head with a curved profile, prominent cheekbones, huge low-set ears, and enormous oval eyes. Some breeders simply call it "the elf cat."

The real difference between a Devon Rex and a Cornish Rex

Both have curly coats and a slender silhouette, but they are genuinely different breeds:

Feature	Devon Rex	Cornish Rex
Mutation	KRT71 Devon variant (recessive, distinct)	KRT71 Cornish variant (recessive)
Coat	Retains all 3 hair types (guard included)	No guard hairs
Texture	Coarser, wavy to curly	Silky, fully marcel-waved
Head	Triangular, prominent cheeks, curved profile	Narrow, curved profile, flat cheeks
Ears	Enormous, set low	Large, set high
Whiskers	Short, crinkled, or absent	Crinkled
Body	Squarer, muscular	Slender, arched back

Visually: the Devon Rex has a pixie face (big cheeks, enormous eyes, low ears), while the Cornish Rex has the narrow, oriental profile of a feline greyhound. They weigh about the same and share a similar temperament.

What the Devon Rex is actually like to live with

Four traits define the breed:

The "monkey in a cat suit" personality. It is the description breeders and owners reach for most often. A Devon manipulates objects with its paws, opens doors and drawers, leaps onto a human shoulder, and fetches small toys to keep a game going. Its intelligence and curiosity rank among the highest in the cat fancy.

Extreme sociability. It greets visitors, seeks constant human contact, and follows its owner from room to room. In this respect it resembles the Sphynx and the Burmese. This is not an aloof cat.

Very high energy. It jumps, chases, and plays for hours, holding onto kitten-like behavior well into adulthood. It needs steady stimulation.

Heat-seeking. Like the Sphynx and Cornish Rex, the Devon carries a light coat and actively hunts for warmth: a human lap, a blanket, a spot under the comforter.

What hereditary health issues it has

This is a breed with a specific health profile that responsible breeders address head-on:

Devon Rex myopathy. An autosomal recessive neuromuscular disease, sometimes called hereditary spasticity. Affected kittens develop progressive muscle weakness from roughly 4 to 7 weeks of age, often showing head bobbing and difficulty swallowing. There is no curative treatment. Genetic screening is still maturing for this condition, so conscientious breeders track litters observationally and retire any parents that produce affected kittens.

Hypertrophic cardiomyopathy (HCM). Present at moderate prevalence. The heart muscle thickens and compromises circulation, and it remains a leading cause of sudden cardiac death across many breeds. Periodic echocardiography is recommended for breeding stock.

Hereditary baldness. Some individuals develop progressive coat loss. It is not uniform across the breed and is usually cosmetic rather than a welfare concern.

Patellar luxation. Documented in specific lines. Radiographic screening of breeding cats is advised.

Cold intolerance. As with the Sphynx and Cornish Rex, the thin coat means a Devon chills easily and needs a heated indoor environment in winter.

Documented average life expectancy runs about 9 to 15 years with appropriate care.

How much grooming does it need

Very little. Although the coat differs from the Cornish (it keeps all three hair types), it asks for no elaborate routine:

Optional, very gentle brushing, not needed weekly.
A damp-cloth wipe-down every 2 to 3 weeks, since the skin produces a moderate amount of sebum that the sparse coat does not absorb.
A bath every 1 to 2 months, optional.
Dental care, which matters because the breed is prone to dental disease.

The Devon Rex sheds very little, so household vacuuming stays light.

How much should a Devon Rex eat

A healthy 7.5 lb (3.5 kg) adult needs roughly 1.4 to 2 oz (40 to 55 g) of premium dry food per day. Because of its high activity and low body weight, calorie density matters:

High animal protein (40 to 50%).
An active-adult or adult-maintenance formula, not an early-senior diet.
Hydration: wet food as a complement, plus access to a pet water fountain, since many Devons prefer moving water.

Does it adapt to apartment life

Yes, with conditions. It needs company and enrichment. What it asks for:

Vertical space: the Devon is an outstanding jumper and climber.
Daily play of 30 to 45 minutes.
Human company for much of the day, or a second sociable cat.
Winter heating: temperatures below about 64 °F (18 °C) do not suit it.

How much does a Devon Rex cost in the United States

A kitten with TICA or CFA registration and tested parents (echocardiogram for HCM, clinical observation for myopathy) runs between $1,200 and $2,500 in 2026. Show lines with championship backgrounds reach $2,800 to $3,800.

A private sale with no documentation carries a real risk of an unscreened cat predisposed to undetected myopathy, which can mean heartbreak and veterinary cost down the line.

Does it get along with other animals

Yes. Its sociability makes shared homes easy:

Other sociable cats (Cornish Rex, Sphynx, Bengal, Abyssinian, Burmese).
Calm dogs, with gradual introductions.
Children over five who respect the cat's space.

Is this breed for you

Yes, if you spend time at home, enjoy hands-on, playful interaction with your cat, have the patience for a feline "monkey," and live in a temperate climate or a heated home.

No, if you work nine or more hours away, live in a cold climate without heating, or want a calm, aloof cat that keeps to itself.

Frequently asked questions

What is the difference between a Devon Rex and a Cornish Rex? Different mutations in the same gene (KRT71). The Devon keeps all three hair types while the Cornish keeps only the undercoat. Visually, the Devon has a pixie face with low ears, and the Cornish has a narrow face with high ears.

Is the Devon Rex hypoallergenic? No. It is a popular myth, but false. The breed produces the Fel d 1 allergen normally.

Does it get along with dogs? Yes, with calm dogs. Its sociable nature makes integration straightforward.

Does it get cold? Yes, in cold climates without adequate heating.

How long does it live? 9 to 15 years. Hereditary myopathy shortens life expectancy in affected individuals.

Does it shed a lot? Very little.
