- Adorable, docile and soft, alpacas are prized as pets and cattle around the world. There are no wild alpacas. Alpacas are domesticated versions of vicuñas, South American ruminants that live high in the Andes. Alpacas are related to llamas, which are domesticated versions of another wild Andean ruminant, the guanaco. While llamas are used as pack animals, alpacas are raised mainly for their soft wool.
