Cat cats are divided into long-haired Napoleon and short-haired Munchkin. Among them, Munchkin is a short-haired cat and not a short-haired cat. However, the short-legged Munchkin can be combined with the long-legged American Shorthair during mating. The kittens born will be short-legged Munchkin and long-legged American Shorthair. A small number of kittens may be combined with the American Shorthair. The appearance is similar to that of Munchkin's short legs, so this is a hybrid breed.
