About the Cornish Rex
The Cornish Rex began in Cornwall, England, around 1950, when a curly-coated cream kitten named Kallibunker was born in a litter on a farm. His owner bred him back to his mother and produced more curly kittens, and the line was built from there. A pair reached the United States in 1956, and the CFA granted championship status in 1964.
The look is distinctive. The body is slender and arched with long legs, a small egg-shaped head and very large, high-set ears. The coat is the main feature. A typical cat has only the soft undercoat layer, without the outer guard hairs, so the hair lies in tight, even waves close to the body. The whiskers and eyebrows are crinkled too. Any colour is accepted.
Temperament and living with one
Cornish Rex cats stay kittenlike for years. They run, leap and climb to the highest point in a room, and many will fetch, play with water and learn tricks. They are affectionate and want to be with people, which includes sitting on a lap or a warm shoulder. A bored one will invent its own entertainment, so give it plenty.
They usually get on well with other cats and with dogs, and tolerate sensible children. They do not enjoy being alone for long. Some are good talkers, though most are less noisy than a Siamese.
Care: coat, food and play
The coat does not need combing, which would damage the waves. Because there is no outer hair, the skin can become greasy over time, and some owners need an occasional bath with a cat-safe shampoo. Dry the cat with a towel and avoid a hot hairdryer, as heat can flatten the curl. Ears gather wax faster than in many breeds and may need cleaning, so ask your vet to show you how.
These cats chill easily and can sunburn in strong light, so a warm room and shaded windows suit them. Many are hearty eaters but stay lean if fed measured portions. Give them tall cat trees, interactive toys and a daily play session.
Health
The breed has a reputation for being robust, and its breeding standard describes no breed-wide inherited disease. Like any cat, it can develop heart disease, so ask your vet whether screening makes sense for your cat. The thin coat gives little insulation or sun protection. Some individuals have sensitive skin or lose hair in patches. Ask a breeder about the health of the parents and about any tests they use.
Is it right for you?
Choose a Cornish Rex if you want an energetic, clinging companion and can supply warmth, company and games. It is a poor fit for a cold house or a long working day away from home. If you like the look but want something calmer, the Devon Rex is similar, and the Selkirk Rex has a plush, heavier coat.
