Maine Coon
Cat breeders are continually competing to find the 'ideal' of the breed – the cats that come closest to fitting the breed standard. Because of this, the physical characteristics of a prize-winning show cat have gradually changed in some breeds. This genetic shifting is most obvious in the two oldest, most popular and most distinctive breeds of show cat - the Persian and the Siamese. However, some show cats are naturally occurring breeds that are perpetuated to keep the original look of a cat from a particular region. Examples are the Maine Coon and Turkish Van.
