Do guinea pigs need to live in pairs?

Yes. Guinea pigs are highly social animals and experience significant stress when kept alone. In Switzerland, it is illegal to keep a single guinea pig. Pair-housed guinea pigs show lower cortisol, better appetite, and longer lifespans.

How much does keeping two guinea pigs cost versus one?

Food costs roughly double; cage size requirements increase (7.5 sq ft minimum for a pair vs 7.5 sq ft for one). Veterinary costs may be higher but welfare improvement justifies the expense.
