The American Curl cat breed has a very interesting history. Sometime in June of the year 1981, the Ruga Family, headed by the husband and wife team of Grace and Joe Ruga who lives in Southern California took in two stray kittens. Both of the stray kitties have these unique curled ears and coats that are a longhaired variety. There’s one that is black coated and the other with black and white colors on its coat. The black and white coated cat was killed in an accident and the black cat which was named Shulamith. Shulasmith is a named that was derived from the Hebrew term which loosely translates to “black but comely”.

The Ruga did not know how unique Shulamith’s curled ears are and assume that it is a trait of a particular cat breed. But further research failed to identify a cat breed with the same curled ears. By the end of 1981, Shulamith and a local longhaired cat mated and produced a litter of four, two of which inherited Shulasmith’s unique shape of ears. Succeeding litters from the two progenitors produced the same results, every litter has one or two kittens with the unique curled ear shape. The family learned, through the help of the cat expert Ms. Nancy Kiester that kittens with curl ears have the genes needed to pass it on their future offspring. This is probably caused by a spontaneous mutation of this cat breed’s genetic makeup.

A serious breeding program was then initiated, selecting only the specimens that have the curled ears. Luckily for the American Curl breed, the gene that produces the curl is dominant and will always appear even if only one of the parents has it. By 1982 the Ruga family, together with Ms. Keister and Mr. Jean Grimm set up the breed’s standard for both hair length varieties. The standard restricted breeding and did not allow other cat pedigrees as outcrosses of the breed being developed. Several years later, the American Curl’s breeding program produced consistent results and by 1986 it was ready to be exhibited for the first time. Today, The American Curl cat breed is still considered to be uncommon when compared to the more popular cats. It is slowly gaining momentum outside the United States and already earned a following in several countries including Japan, France, Russia and Spain.
