The following is a list of experimental cat breeds and crossbreeds that do not have the recognition of any major national or international cat registries, such as The International Cat Association (TICA) in the US, Europe, and Australasia; the Governing Council of the Cat Fancy (GCCF) in the UK, the Fédération Internationale Féline (FiFE) in continental Europe, the Cat Fanciers' Association (CFA) in North America, or the more recent World Cat Federation based in Germany. Such a breed may be recognized by one of the smaller cat registries. Smaller registries include the Rare and Exotic Feline Registry (REFR), the Dwarf Cat Association (TDCA), and others. This list only includes breeds recognized by at least one extant, national or international, multi-breed registry.
