## Quick answer

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.

## Social herd animals

Guinea pigs evolved as prey animals living in groups and should never be kept alone — a solitary guinea pig becomes lonely and stressed. Same-sex pairs or small groups work well, with careful introductions. They communicate through wheeking (food excitement), purring, chutting, and rumble-strutting during dominance displays.

## Help protect the Guinea Pig

Guinea pigs are often bought for children and abandoned when families underestimate their social and dietary needs.
