A moggy is any cat which has not been intentionally bred. Moggies lack a consistent appearance unlike purebred cats that are selectively bred for appearance conforming to a standard. In contexts where cats need to be registered—such as in veterinary practices or shelters—moggies may be called domestic short-haired (DSH) or domestic long-haired (DLH) cats, depending on coat length . The vast majority of cats worldwide lack any pedigree ancestry.
