The Abyssinian Guinea Pig takes its name not from the Ethiopian region of Abyssinia but from a historical naming convention applied to various exotic animals and goods during the Victorian era. This misnomer has persisted despite having no geographical connection to Africa—like all domestic guinea pigs, Abyssinians descended from South American wild cavies. The breed represents one of the oldest recognized guinea pig varieties, documented in European collections since the 16th century.
Within the cavy fancy community, Abyssinians are sometimes called "Abby" or "Abbies" as affectionate shorthand. The scientific name Cavia porcellus applies to all domesticated guinea pigs regardless of breed, with Abyssinian referring specifically to the coat type characterized by multiple rosettes creating the breed's signature disheveled appearance.
Abyssinians compete in their own breed classification at guinea pig shows, judged on rosette placement, coat quality, and overall conformation according to standards established by organizations like the American Cavy Breeders Association. Show-quality Abyssinians display eight to ten well-formed rosettes arranged symmetrically, though pet-quality individuals with fewer or irregularly placed rosettes make equally wonderful companions.
