A cat registry is an organisation that registers cats for exhibition and breeding purposes. A cat registry stores the pedigrees (genealogies) of cats, prefixes or affixes of catteries, studbooks (lists of authorised studs of recognised breeds), breed descriptions and the standards of points (SoP) for those breeds; lists of judges qualified to judge at shows run by, or affiliated with, that registry. A cat registry is not the same as a cat club or breed society (these 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).
