What Guinea Pigs Need in an Enclosure
Guinea pigs are ground-dwelling social animals that need maximum floor space. They do not climb or burrow. C&C (Cubes & Coroplast) grid cages are the gold standard — fully customisable, easy to clean, and far more space-efficient per dollar than commercial pet store cages. Must be kept in same-sex pairs or groups.
⚠️ Things to Avoid for Guinea Pigs
- Pet store guinea pig cages — nearly all are criminally undersized
- Enclosures under 7.5 sq ft for a pair
- Wire mesh floors — causes sore hocks
- Aquariums — insufficient ventilation for ammonia from urine
- Housing a single guinea pig alone
