A cat registry or cat breed registry, also known as a cat fancier organization, cattery federation, or cat breeders' association, is an organization that registers domestic cats (usually purebred) of many breeds, for exhibition and for breeding lineage tracking purposes. A cat registry stores the pedigrees (genealogies) of cats, cattery names, and other details of cats; studbooks (lists of authorized studs of recognized breeds), breed descriptions, and the formal breed standards (a.k.a. standards of points or SoP); lists of judges qualified to judge at shows run by or affiliated with that registry, and sometimes other information. A cat registry is not the same as a breed club or breed society (these are specific-breed organizations that may be affiliated with one or more registries with whom they have lodged breed standards in order to be able to exhibit under the auspices of that registry). Cat registries each have their own rules and usually also organize or license (sanction) cat shows. The show procedures vary widely, and awards won in one registry are not normally recognized by another. Some registries only serve breeders, while others are oriented toward pet owners and provide individual as well as cattery memberships, while yet others are federations only deal with breed clubs or even other registries as intermediaries between the organization and breeders.
