Persian cats can have any colour or markings except Siamese, including torty, blue, and tabby. There was an attempt to establish the silver Persian as a separate breed called the Sterling, but it was not accepted and silver and gold longhaired cats are judged in the Persian category of cat shows.
Because their fur is too long and dense for them to maintain themselves, Persian cats need extensive and regular grooming. To keep their fur in tiptop condition they must be bathed regularly, dried carefully afterwards, and brushed thoroughly every day. Their eyes need to be checked for problems on a regular basis because some animals have trouble keeping them clean.
A Persian cat without an established and registered pedigree is classed as a domestic longhair cat.
