An Oriental bicolour is any cat of Oriental type, either long-haired or short-haired and in any pattern including colourpoint, which has white areas on its coat caused by the white spotting gene. In most cat fancier and breeder organisations, Oriental bicolours do not constitute a standardised breed, but a coat pattern variant of the breed of their foundation stock. One breed registry is an exception, the UK-based Governing Council of the Cat Fancy (GCCF), which has defined them as a separate breed named Oriental Bicolour (capitalised).
