In Switzerland, you must own guinea pigs in pairs

The Short Answer

TRUE! Social animals must be given "adequate social contact with animals of the same species." For guinea pigs, this means you cannot legally own just one.

The Full Story

Switzerland passed comprehensive animal welfare laws in 2008 recognizing that animals have social needs. The law created an unexpected problem: guinea pigs rarely die at the same time. If one dies, you need to get another companion - creating an endless guinea pig cycle.

The Solution: Priska Küng runs a "rent-a-guinea-pig" service near Zürich. She houses ~80 guinea pigs and rents older ones as companions for bereaved guinea pigs. Cost: 50-60 Swiss francs deposit, half returned when the rental pig is returned.

Animals also covered: mice, gerbils, rats, degus, chinchillas, Japanese quails, macaws, cockatoos, parakeets, parrots, canaries, lovebirds, and goldfish (they're schooling fish).

Important Exception: Golden hamsters are explicitly EXCLUDED - they're naturally solitary and will fight if housed together.

Common Misconceptions

People often think this applies to all pets or that you can substitute other animals as companions. The law specifically requires same-species companionship. Some believe it's just a suggestion or guideline, but it's actually enforceable law with potential penalties.

Actual Legal Text

Social animals must be kept in groups of at least the minimum number required for the species. Guinea pigs (Cavia porcellus) are classified as social animals and must be kept with at least one companion of the same species.
