Bengal cats have "wild-looking" markings, such as large spots, rosettes, and a light/white belly, and a body structure reminiscent of the Asian Leopard Cat (Prionailurus bengalensis bengalensis).The Bengal cat has a desirable "wild" appearance with a gentle domestic cat temperament, provided it is separated by at least three generations from the original crossing between a domestic feline and an ALC. The name Bengal cat was derived from the taxonomic name of the Asian Leopard Cat (P. b. bengalensis), and not from the unrelated Bengal tiger. The Bengal cat is usually either classed as a brown-spotted or snow-spotted (although there are more colours, brown and snow are the only colours of Bengal that the Governing Council of the Cat Fancy (GCCF) recognise. Within brown Bengals, there are either marble or spotted markings. Snow Bengals are also either marble or spotted but are also divided into blue-eyed or AOC (Any Other Colour) eyes. The International Cat Association (TICA) recognizes several Bengal colours (brown, seal lynx point, mink, sepia, silver) and patterns (spotted and marbled) for competition. In the New Traits class, other colours may be shown, as well as longhairs. After three generations from the original crossing, the breed usually acquires a gentle domestic cat temperament; however, for the typical pet owner, a Bengal cat kept as a pet should be at least four generations (F4) removed from the Leopard Cat. The so-called "foundation cats" from the first three filial generations of breeding (F1–F3) are usually reserved for breeding purposes or the specialty pet home environment.
