  • Continuous stress can also be a problem that can lead to severe depression in guinea pigs. Being cooped up on a small cage, being moved from time to time, etc. can also be a significant problem.

As guinea pigs are social animals, they form a strong bond with their cage mates.

A companion is crucial for guinea pigs as it provides them with social interaction and company.
