The Alpaca Guinea Pig takes its name from the South American Alpaca camelid, whose soft, wavy fleece the guinea pig's coat resembles. This breed represents one of the rarer long-haired varieties, combining the forward-growing coat pattern characteristic of Peruvian guinea pigs with the wavy or loosely curled texture derived from Rex genetics. The result creates a flowing, textured coat distinct from both straight-haired Peruvians and tightly curled Texels.
The scientific classification Cavia porcellus applies to all domestic guinea pigs regardless of coat type. The Alpaca variety has achieved recognition from some breed registries while remaining classified as developing or rare by others. Not all cavy organizations worldwide recognize Alpacas as a distinct breed, with some considering them variants of other long-haired curly types.
Alpacas share genetic heritage with several related curly long-haired varieties including Texels and Merinos, differing primarily in coat growth patterns and curl tightness. The breed's development involved crossing Peruvians (for coat length and forward growth direction) with curly-coated varieties (for wave pattern). Dedicated breeders continue refining the type, working toward consistent expression of the distinctive flowing waves that define quality Alpacas.
