Domestic shorthair

Cat

A domestic short-haired cat is a short-haired domestic cat of mixed ancestry that does not belong to a recognized cat breed. In the cat fancy, such cats are designated Domestic Shorthair (DSH), a pseudo-breed, for registry classification purposes (uncommonly, some such cats are actually pedigreed). Domestic short-haired cats should not be confused with the British Shorthair, American Shorthair or other breeds with "Shorthair" names, which are breeds recognized by the Cat Fanciers' Association (CFA)[1] and other registries. In original English, they are often affectionately nicknamed moggies, as a generalization for no particular breed.
