Tortoiseshell is a cat coat coloring named for its similarity to tortoiseshell material. The most common coats are tabby, tortoiseshell, calico and solid colours. Additionally, the FIF recognizes the colors in tortoiseshell, tabby, and tortoiseshell-tabby coat patterns. Not all cats with Klinefelter syndrome have tortoiseshell or calico patterns. Domestic long-haireds come in all genetically possible cat colours including tabby, tortoiseshell, bi-coloured, and smoke. Like calicos, tortoiseshell cats are almost exclusively female. Tortoiseshell and calico coats result from an interaction between genetic and developmental factors. It is also possible to have a tortoiseshell or tabby point. However, outside North America, the calico pattern is more usually called "tortoiseshell and white". Some European associations also accept red, cream, caramel, apricot and tortoiseshell, cinnamon and fawn. The fur comes in many colors and patterns, including self, tortoiseshell, brindle, and part-color. This ornamental comb, usually in tortoiseshell color, originated in the 19th century. Hawksbill shells were the primary source of tortoiseshell material used for decorative purposes. Prominent invertebrate species include California tortoiseshell butterflies. A little bone comb is bound to the lower broad end of the tortoiseshell.
