The American Bobtail is most notable for its stubby "bobbed" tail about one-third to one-half the length of a normal cat's tail. This is the result of a cat body type genetic mutation affecting the tail development, similar to that of a Manx cat. American Bobtails are a very sturdy breed, with both short- and long-haired coats. Their coat is shaggy rather than dense or fluffy. They can have any color of eyes and coat, with a strong emphasis on the "wild" tabby appearance in show animals.
