Guinea pigs are friendly and talkative, but they are not low-maintenance starter pets. They need company of their own kind, enough floor space, daily fresh vegetables and a reliable source of vitamin C.

## Never keep one alone

Guinea pigs are social animals. A compatible pair or small group is usually much better than a single animal. Make sure sexes are correctly identified, because accidental litters are common and risky.

## Health checks

A healthy guinea pig is alert, moves well, has clear eyes, a clean nose, clean rear end and a good coat. Avoid animals with crusty eyes, sneezing, bald patches, wounds, diarrhoea or noisy breathing. Ask about age, diet and whether the animal is used to handling.

## Housing and food

Most shop cages are too small. Guinea pigs need a spacious enclosure, hiding places, hay at all times, pellets with vitamin C and fresh vegetables. They are prey animals, so calm handling and predictable routines matter.
