Longhair, also called Persian, breed of domestic cat noted for its long, soft, flowing coat. Long-haired cats were originally known as Persians or Angoras. These names were later discarded in favour of the name longhair, although the cats are still commonly called Persians in the United States. The longhair, a medium-sized or large cat with a cobby (stocky), short-legged body, has a broad, round head, a snub nose, and a short, heavily haired tail. The large, round eyes may be blue, orange, golden, green, or copper-coloured, depending on the colour of the cat. The soft, finely textured coat forms a heavy ruff about the neck.
The longhair is bred in several colour varieties. The solid, or self, colours are white, black, blue, red, and cream. Patterned coats include shaded silver and black (smoke); silver, brown, blue, or red with darker markings (tabby); white finely ticked with black (chinchilla); cream, red, and black (tortoiseshell); calico, or tortoiseshell and white; blue-grey and cream intermingled (blue cream); and bicoloured. The colours of tortoiseshells, calicos, and blue creams are genetically linked with the sex of the cat. Almost all are females, and most of the few males are sterile. Blue-eyed white cats may be deaf.
Longhair cats, although generally considered more languorous than short-haired cats, are, like shorthairs, noted for playfulness, affection, and the ability to defend themselves if necessary.
