Companion Animals

Companion Guinea Pig Social Needs

Guinea pigs are highly social animals that suffer significantly when kept alone, requiring at least one compatible companion for good welfare.

Key Facts

Guinea pigs are social animals that use vocalisations to maintain contact with companions
Lone guinea pigs show increased stress hormones and stereotypic behaviours
Germany and Switzerland have laws requiring that guinea pigs be kept in pairs or groups
Guinea pig companionship requires careful introduction to prevent aggression
Same-sex pairs or neutered male-female pairs are most suitable for most owners

Welfare Considerations

Keeping guinea pigs alone is a significant welfare compromise that causes chronic social deprivation and stress. The simple welfare requirement for companionship is often overlooked by owners. Single-housed guinea pigs frequently show stereotypic behaviour and reduced activity that improves dramatically when paired appropriately.

What You Can Do

Always keep guinea pigs in bonded pairs or small groups, never alone
