The American Shorthair is a pedigreed cat breed, with a strict conformation standard, as set by cat fanciers of the breed and the North American cat fancier associations such as The International Cat Association (TICA) and the Cat Fanciers' Association.
The British Shorthair is the pedigreed version of the traditional British domestic cat, with a distinctively chunky body, dense coat and broad face. The most familiar color variant is the "British Blue", a solid blue-gray with copper eyes, medium tail, but the breed has also been developed in a wide range of other colours and patterns, including tabby and colorpoint.
As with most other cat breeds, color varieties of the Siberian vary and all colors, such as tabby, solid, tortoiseshell and colorpoint, are genetically possible. The Siberian cat breed does not have any unusual, distinct, or unique fur colorations or patterns.
