Question: where do guinea pigs live in the world

title: Guinea pig
text: C. porcellus is not found naturally in the wild ; it is likely descended from closely related species of cavies , such as C. aperea , C. fulgida , and C. tschudii , which are still commonly found in various regions of South America . Studies from 2007 -- 2010 applied molecular markers and studied the skull and skeletal morphology of current and mummified animals , thereby revealing the ancestor to most likely be Cavia tschudii . Some species of cavy identified in the 20th century , such as C. anolaimae and C. guianae , may be domestic guinea pigs that have become feral by reintroduction into the wild . Wild cavies are found on grassy plains and occupy an ecological niche similar to that of cattle . They are social , living in the wild in small groups that consist of several females ( sows ) , a male ( boar ) , and the young ( which , in a break with the preceding porcine nomenclature , are called `` pups '' not `` piglets '' ) . They move together in groups ( herds ) eating grass or other vegetation , and do not store food . While they do not burrow themselves or build nests , they frequently seek shelter in the burrows of other animals , as well as in crevices and tunnels formed by vegetation . They tend to be most active during dawn and dusk ( crepuscular ) , when it is harder for predators to spot them .
