American Curl History

The American Curl cat is an unusual breed with distinctive ears that gently curve backward. The backward curling ears are a result of a dominant mutation. This mutation was first documented in 1980 when a stray long-haired cat with curled ears was taken in by Grace Ruga and named “Shulasmith”. A subsequent unplanned litter resulted in two of the four kittens having curled ears. The first time these American curls, Shulasmith and the 2 kittens, were shown was at Palm Springs in 1983 where they created a lot of interest and excitement. Since the curled ears seemed to be a dominant mutation, Joe and Grace Ruga and a friend, Nancy Keister, started a selective breeding program with the intent of developing a new cat breed. The American Curl was first recognized in the US by the International Cat Association and later in 1991 was given provisional recognition by the Cat Fanciers’ Association (CFA).

American Curl Cat


The American Curl is a small to medium-sized cat breed with distinctive curled ears. Male Curls weigh from 7 to 10 pounds and females from 5 to 8 pounds. Curl kittens are born with uncurled ears but they become tightly curled within a week and then gradual uncurl until they reach their adult state in 4 to 5 months. The degree of final curling varies between individual cats with show quality ears ranging between 90 and 180 degrees arc of curl. Curls are elegant, moderately muscled and slender in build with a rectangular body. The head has a wedge shape that is slightly longer than wide and the eyes are fairly large, walnut-shaped – oval on top and rounded at the bottom. Longhair varieties have a semi-long fine, silky and flat-lying coat with a minimal undercoat and a fully plumed tail. Shorthair varieties have a short, soft, silky and flat-lying coat with a minimal undercoat.
