CFA describes the Cornish Rex as the racy elegance of a greyhound paired with a clown's personality, dressed in curls [1]. Its close-lying marcel waves have no guard hairs at all, making the coat unbelievably soft [1]. Corneys are very active, intelligent and intensely devoted [1]. The breed is recognised by CFA, TICA [7], FIFe [2] and GCCF [3].

History

In 1950 a curly-coated cream male kitten, Kallibunker, turned up in a litter of barn cats on Nina Ennismore's farm in Cornwall, England [1]. After consulting her vet and a geneticist, she bred him back to his mother and got two more curly kittens [1]. Having kept Rex rabbits, she gave the new cat breed the same name [1]. Crosses with Burmese, Siamese and British Shorthairs showed the mutation was recessive [1]. A California breeder bought a pair in 1956 to start the breed in the US; CFA accepted it for registration in 1962 and for championship two years later [1].

Appearance

  • Coat: short, close-lying tight waves with no guard hairs; it must be dense and soft. CFA's standard gives the coat 40 points on its own [1].
  • Body: lean and statuesque, with an arched back [1].
  • Head: egg-shaped, with large high-set ears, huge luminous eyes and a prominent Roman nose [1].

Temperament

Cornish Rex are extremely intelligent, adaptable and adventurous, and they love to travel [1]. They're also devoted, often called "Velcro kitties" for their need for physical contact with their person [1]. Their energy means a constant hunt for new playthings, appropriate or not, so put fragile things away [1]. Children and adults enjoy their antics, and dogs get a willing playmate [1]. They'll chat, but not loudly or needlessly [1].

Care

  • Coat: no regular combing needed. Bathe occasionally if the coat gets greasy; towel-dry and never blow-dry [1].
  • Ears: wax builds up faster than in other breeds; clean often with a cotton ball or swab [1].
  • Warmth and sun: they chill easily and can sunburn [1].
  • Food: big appetites despite slim builds [1].

Health

  • Inherited conditions: CFA describes a sturdy breed with none [1].
  • Skin and coat: the guard-hair-free coat is fragile and may not protect against sun; they chill easily [1].
  • Ears: wax builds up quickly; clean often [1].
  • Lifespan: GCCF estimates about 16 years [3]. We found no breed-specific longevity study.

Fun facts

  • The breed is named after Rex rabbits [1].
  • Never blow-dry a Cornish Rex [1].
  • They may eat vegetables and fruit [1].

Frequently asked questions

Does a Cornish Rex need a sweater?

It may help. With no guard hairs they chill easily in cold weather, and CFA suggests a sweater. The thin coat may not protect against sun either [1].

How is a Cornish Rex different from a Devon Rex?

The Cornish has no guard hairs, tight even waves, a slender arched body, an egg-shaped head and a Roman nose [1]. The Devon has a few guard hairs, a looser wave and huge low-set ears [4]. They carry different mutations [4].

Does a Cornish Rex need brushing?

Regular combing isn't needed. Occasional baths help if the coat gets greasy; towel-dry thoroughly and never use a blow dryer [1].
