American Curl

Cat breed · United States

Overview

The American Curl is a cat characterised by its unusual ears, which curl back from the face toward the center of the back of the skull. The breed originated in Lakewood, California, due to a spontaneous mutation.

History

History: The first American Curls appeared as strays on the doorstep of the Rugas in Lakewood, California in June 1981. The black female, named Shulamith, gave birth to a litter of cats with the same curled ears, and so became the ancestor of all American Curls today. In 1986, an American Curl was exhibited at a cat show for the first time, and in 1992, the longhaired American Curl was given championship status by The International Cat Association (TICA). In 1999, the American Curl became the first breed admitted to the Cat Fanciers' Association (CFA) Championship Class with both longhair and shorthair divisions.

The American Curl is a medium-sized cat 5–10 lb (2.3–[dose — ask your vet]), and does not reach maturity until 2–3 years of age. Females should be between 5–8 lb (2.3–[dose — ask your vet]) and males 7–10 lb (3.2–[dose — ask your vet]).

American Curl kittens are born with straight ears, which begin to curl within forty-eight hours. After four months, their ears will not curl any longer, and should be hard and stiff to the touch at the base of the ear with flexible tips. A pet-quality American Curl may have almost straight ears, but showcats must have ears that curl in an arc between 90 and 180 degrees. A 90 degrees is preferable, but cats will be disqualified if their ears touch the back of their skulls.

Every pet is one of a kind. This guide covers what's typical for the breed, but your own dog or cat will have their own personality, quirks and needs — think of it as a friendly starting point, not the final word.
