The Van cat is a distinctive landrace of domestic cat found mainly in the Lake Van region of eastern Turkey. It is large, all-white, and frequently odd eyed. Many sources consider it to be an Armenian cat. The naturally occurring Van cat type is the basis of the Turkish Van breed, internationally selectively bred with a more recently developed ruddy colouring pattern on the white, as standardised and recognised by many cat fancier organisations.
The cats are notable for their lean, long-legged appearance. They are reported to like water more than most cats, and have been seen swimming in Lake Van. Their most notable genetic characteristic is their almond-shaped eyes that often are mismatched colours. The most valued and valuable members of the type generally have one amber-green eye and one blue eye. (Source: Wikipedia)
