 Not all registries recognise all of these colour variations.While a few registries recognise all-white specimens as Turkish Vans, most do not.The US-based Cat Fanciers' Association (CFA, the world's largest registry of pedigreed cats) and Fédération Internationale Féline (FIFe, the largest international cat fancier organisation) recognise only van-patterned specimens, as they define the breed by both its type and pattern.
