American bobtails are a very sturdy breed, with both short or longhaired coats. Their coat is shaggy rather than dense or fluffy. They can have any colour of eyes and fur, with a strong emphasis on the "wild" tabby appearance in show animals.
According to legend, bobtails are the result of a crossbreeding between a domestic tabby and a bobcat. This is not genetically possible, and the unusual tail is actually the result of a random genetic mutation. The breed was recognised by the International Cat Association in 1989.
