The Devon Rex and Cornish Rex are both curly-coated cats with large ears, but their coats, body shapes, and head profiles differ in recognizable ways. Knowing those distinctions can help you compare the breeds while keeping in mind that appearance alone cannot confirm pedigree.
Devon Rex vs. Cornish Rex at a glance
Both breeds have short, soft coats and an alert, fine-boned appearance. The quickest visual comparison is often the coat: a Devon Rex typically has loose waves or curls with a varied texture, while a Cornish Rex is known for a close-lying coat made up largely of soft undercoat. Other clues include the Devon’s broader, more rounded head and the Cornish Rex’s longer, more curved profile.
| Feature | Devon Rex | Cornish Rex |
|---|---|---|
| Coat impression | Loose waves or curls; texture can vary | Short, close-lying, softly waved coat |
| Head and profile | Broad, short wedge with prominent cheekbones and a noticeable stop | Longer, narrower wedge with a distinct Roman curve to the profile |
| Body | Fine-boned and muscular, with a broad chest | Slender, long-legged, and arched |
| Ears | Very large and set low on the head | Large and set high on the head |
| What appearance can establish | Similarity to the breed standard, not pedigree by itself | Similarity to the breed standard, not pedigree by itself |
These are general breed characteristics, not a checklist that every individual will match exactly. Age, coat condition, lighting, grooming, and mixed ancestry can all affect what you see.
How do their coats differ?
The two breeds have distinct coat patterns at the level of texture and growth. A Cornish Rex’s coat is very short and typically lacks the longer guard hairs found in many cats. Its soft waves can form ridges along the back and sides. The coat may look especially sleek or rippled depending on its length, condition, and how the light falls on it.
A Devon Rex also has a short, soft coat, but its curls may look looser and more irregular. Some Devons have areas where the coat is thinner, and the amount of curl can vary across the body or over time. These differences mean that “curly fur” alone is not enough to distinguish the breeds.
Neither breed should be treated as truly hypoallergenic. Cat allergies are often triggered by proteins found in saliva and skin flakes, rather than by fur alone. A short or unusual coat does not guarantee that an allergic person will have fewer symptoms.
What do their head shapes and bodies look like?
Both breeds have prominent ears and large, expressive eyes, but the ears sit differently. A Devon Rex’s ears are exceptionally large and low-set, framing a broad head. The head is often described as a short wedge, with full cheekbones and a clear change in direction between the forehead and nose.
The Cornish Rex has a narrower, longer head, with a profile that curves from the forehead toward the nose. Its ears sit high, and the overall outline tends to look elongated. When comparing photographs, a side view can make this profile easier to see than a straight-on portrait.
Both cats are lithe and athletic rather than heavy-bodied. The Devon Rex generally has a broad chest and a compact, muscular impression. The Cornish Rex is typically longer in the body, with a high arch over the back and long legs. Individual cats can fall outside the typical outline, so body shape is most useful when considered alongside coat and head features.
Are the Devon Rex and Cornish Rex related?
They are separate breeds that developed from different curly-coated cats in the United Kingdom. The Devon Rex originated in Devon, England, and the Cornish Rex in Cornwall. Their coats result from different inherited traits; the shared “Rex” name refers to a curly or wavy coat, not to a single breed or identical coat type.
Because the breeds are distinct, a Devon Rex is not simply a Cornish Rex with a different face, and vice versa. Breed registries maintain their own standards. For a pedigreed cat, registration records and documentation from a reputable breeder provide evidence of ancestry that visual resemblance cannot supply.
Does coat color tell you which breed a cat is?
No. Coat color and pattern are separate from breed. Devon Rex and Cornish Rex cats can appear in many colors and patterns, so a solid, tabby, tortoiseshell, pointed, or bicolor coat does not identify one breed over the other. The same colors and patterns can also occur in domestic cats with no documented pedigree.
A domestic cat can have short, wavy, or sparse-looking fur and prominent ears without being a Devon Rex or Cornish Rex. “Looks like a Rex” is a useful description of appearance, but it is not a reliable ancestry claim. If the distinction matters for registration, breeding, or a veterinary history, use documented pedigree information and consult the relevant registry or a qualified professional.
What should you consider when choosing between them?
Choose based on the individual cat’s needs, temperament, and care requirements rather than assuming the breed determines personality. Breed descriptions may mention common tendencies, but they do not predict how a particular cat will behave. Early experiences, socialization, health, and the cat’s own disposition matter, too.
Both breeds have short coats that still need routine care. Check the skin and coat gently, keep nails trimmed, and ask a veterinarian how often bathing or ear cleaning is appropriate for the individual cat. Avoid assuming that every Rex needs frequent baths: skin and coat condition vary, and over-cleaning can irritate skin.
Before adopting or buying, ask about veterinary records, the cat’s background, and any health screening relevant to its family line. A responsible breeder should be able to discuss health history and provide documentation. If adopting, shelter staff may know the cat’s behavior and medical needs even when its breed ancestry is unknown.
How can you identify a Devon Rex or Cornish Rex?
Start by comparing several features together: coat texture, head profile, ear placement, and body outline. Look at the coat in good light without relying on a single patch or photograph. A broad head with low-set ears and looser curls may be more consistent with a Devon Rex; a narrow curved profile, high-set ears, and a close-lying wavy coat may be more consistent with a Cornish Rex.
That comparison can suggest resemblance, but it cannot confirm breed. Mixed-breed cats may share some traits, and coat appearance can change with age or health. When certainty matters, check pedigree records or seek an assessment from a knowledgeable breed professional. For everyday care, a veterinarian’s evaluation of the cat itself is more useful than a visual breed guess.
