The Cornish Rex, also called Corn Rex, is a domestic cat breed that originated from a genetic mutation that caused it to have no fur, only down hair that is very fine and wavy. Also known as the Gazelle, Greyhound, or Whippet of cats, it has a long, athletic, curved body, wide hips, and a social, intelligent, affectionate, trainable personality.

Cornish Rex Traits: What to Know Before You Buy

  • The Corn Rex personality is very active, curious, and social, and therefore needy in terms of companionship and attention. This breed isn’t recommended for people who want a more solitary, independent cat.
  • Contrary to popular belief, the Corn Rex is not hypoallergenic, but it has minimal shedding. People who are allergic to pet dander are less sensitive to this breed.
  • This breed has more risk of skin problems such as rashes and sunburn because it doesn’t have an outer coat to absorb natural oils and protect the skin. Special care must be given to properly protect and wash its skin.

The story of the Cornish Rex dates back to the 1950s. A British shorthair belonging to certain Nina Ennismore, of Cornwall birthed a kitten which had a short curly coat and a slender, long-limbed build.

The pet was named Kallibunker and its descendants subsequently mixed with British shorthairs, Burmese, and Siamese. However, in spite of the original owner’s earlier desire to continue the breed, the population all but vanished from her home country by the close of the decade.

Fortunately a couple of them had been shipped to the States. There they were further crossed with a selection of other breeds including the American shorthair and the Havana Brown. And by the middle of the following decade, the Cornish Rex was recognized by the Cat Fancier’s Association.
