The Munchkin is distinguished by a spontaneous dominant mutation that shortens the cat's legs. Except for their disproportionately short legs, cats should be well-balanced. It is important that the legs be straight, never bowed or cow-hocked. The head shape is an equilateral triangle. All colors and patterns, as well as both longhaired and shorthaired varieties, are accepted for competition. The longhaired Munchkin's coat is silky, semi-long and ends in a fully plumed tail. Munchkins are kittenish, outgoing and respond well to handling..
