Specific registries have particular, and differing, standards of points with regard to coloration and patterning. For example, the Governing Council of the Cat Fancy (GCCF) classifies the Manx as a variant of the British Shorthair (BSH), and thus requires that Manx cats to have one of the coat patterns that would be permissible in the BSH rather than any that is exclusive to a "foreign" type (e.g. point colouration). New Zealand Cat Fancy (NZCF) does likewise for colour and markings, but requires a double-coat and other Manx-specific features that GCCF does not. Some other registries are even more restrictive, while others are more liberal.
