The American Cavy Breeders Association (ACBA) is a national specialty club under the American Rabbit Breeders Association (ARBA). Like many other specialty clubs under ARBA, the ACBA maintains a membership, awards sweepstakes points, provides special awards, publishes a newsletter and contributes to developing new standards. The ACBA has wider responsibilities than other specialty clubs under ARBA because it is the only national specialty club for cavies and supports all currently recognized breeds, whereas most of the other ARBA national specialty clubs are devoted to a single rabbit breed. The exceptions are a handful of very similar breeds with combined clubs.
