Well first some history of this beautful Cat: while some new cat breeds have had a difficult time gaining acceptance by cat lovers, the American Curl has purred his way into the hearts of judges and cat lovers in an crazy short time. The breed came about in June 1981 as an all of a sudden genetic mutation in the domestic cat population. By 1986 it was recognized by two of the largest cat registries. Its looks? At birth, Curl kittens look like any other kitten, but between one and seven days the ears get firmer and start to push up and curve back. The degree of ear curl can vary from 90 to 180 degrees, American Curls are playful and energetic. They also display the typical cat curiosity and want to be right there to investigate any changes in their environment.
