History of the American Curl:

The American Curl is a distinctive looking cat with backwards curling ears. The cat is relatively rare outside the USA.

The history begins in June 1981 when Joe and Grace Ruga (Curlniques Cattery) found two homeless kittens in Lakewood, California. One was a black longhaired female who they named Shulamith, the other a semi-longhaired black and white  female who they named Panda. Both of these kittens had unusual curled back ears.

Panda vanished a few weeks after the Ruga’s took her in, but Shulamith remained. In December 1981, Shulamith gave birth to a litter of four kittens, two of whom had their mother’s curled back ears. The Rugas realised this was potentially a new breed and set about establishing a breeding programme.

Shulasmith and two of her kittens were exhibited at a CFA cat show held at Palm Springs in California, in 1983 and proved to be a big hit. In 1985 TICA formally recognised this new breed and CFA accepted them in 1986.

The gene responsible for the curled back ears (Cu) is dominant, which means that only one copy of the gene is needed for the offspring to inherit the trait.  There are no known side effects of this gene and cats with curled ears can be mated with one another. American Curl cats can still produce straight eared offspring which are known as “American Curl Straight Ear”.

The distinctive curled back ears are the most prominent feature on the American Curl. All kittens are born with straight ears, they begin to curl back into a tight “rosebud” around 3-5 days of age, until they gradually unfurl, permanently “setting” at around 16 weeks old.

The American Curl is a medium sized cat, with a long, lean, rectangular shaped body that is well proportioned.

The head is a modified wedge shape and is longer than it is wide. The ears curl out and back, exposing hairy tufts. They feel somewhat less flexible than other cat ears. The nose is straight, chin strong and have large, walnut-shaped eyes and prominent whisker pads.

The cat can come in short or semi-long hair and comes in all colours and patterns, there is virtually no undercoat and the coat should feel soft and silky.

The American Curl is a people loving cat that is inquisitive, intelligent and likes to be involved in everything you are doing, they are not especially talkative or quiet.

Words used to describe the American Curl include even-tempered, adaptable, friendly, curious,  it is said they retain their kitten-like nature all their lives. They are known to greet their human companions with a friendly headbutt.

This is a breed which gets on well with children and other pets and make an exceptional family pet.

Special care:

The gene pool for the American Curl is large and no health conditions are known. Due to the fact they are more rigid than in other breeds, special care must be taken when handling the ears.
