List of experimental cat breeds

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.

There are hundreds of chicken breeds in existence.

List of goose breeds

This list contains breeds and landraces of domestic geese as well as species with semi-domestic populations. Geese are bred mainly for their meat, which is particularly popular in Germanic languages countries around Christmas. Of lesser commercial importance is goose breeding for eggs, schmaltz, or for the fattened liver.

List of guinea pig breedsW
List of guinea pig breeds

There are many breeds of guinea pig or cavy which have been developed since its domestication circa 5000 BCE. Breeds vary widely in appearance and purpose, ranging from show breeds with long, flowing hair to laboratory breeds being used as model organisms for science. From roughly 1200 to 1532 CE, selective breeding by indigenous South American people resulted in many landrace varieties of domestic guinea pigs, which form the basis for some formal modern breeds. Early Andean varieties were primarily kept as agricultural stock for food, and efforts at improving cavy breeds (cuy) bred for food continue to the modern era, with entirely separate breeds that focus on size and disease resistance.

List of horse breedsW
List of horse breeds

This article is a list of horse and pony breeds with articles on Wikipedia, and also includes terms for types of horse that are not necessarily standardized breeds but are often labeled as breeds. While there is no scientifically accepted definition of the term "breed", a breed is generally defined as having distinct true-breeding characteristics over a number of generations. Its members may be called "purebred". In most cases, bloodlines of horse breeds are recorded with a breed registry. The concept is somewhat flexible in horses, as open stud books are created for recording pedigrees of horse breeds that are not yet fully true-breeding.

List of rabbit breedsW
List of rabbit breeds

As of 2017, there were at least 305 breeds of domestic rabbit in 70 countries around the world. A rabbit breed is a distinct variety created through natural selection or, more often, through selective breeding for specific characteristics, including size, fur, feed conversion ratio, climate adaptability, or temperament. Groups such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) coordinate and standardize the desired qualities of their recognized breeds, through promotion and exhibition. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the purpose for the breed, often defined by the individual breed standard by which it may be judged. The global diversity of breeds reflects the breadth of the rabbit's unique qualities. Listed below are 191 of the world's modern-day rabbit breeds.
