Diet overview

Guinea Pigs are mammals that rely on herbivore — hay, fresh vegetables, and guinea-pig pellets with vitamin c. Guinea pigs are domesticated rodents from the Andes, kept worldwide as gentle pets that need company, unlimited hay, and vitamin C in their diet. They live 5–7 years, communicate with wheeks and purrs, and unlike many rodents cannot manufacture their own vitamin C.

Feeding behaviour

Foraging strategy varies by season. Guinea Pigs may hunt, graze, filter-feed, or scavenge depending on ecology.

Role in the food web

As mammals, they interact with predators, prey, and competitors across their range.

Human-related feeding risks

Never feed wild guinea pigs — it habituates animals to people and can spread disease.
