Tell me why your Peruvian baby guinea pig was so frightened when you first brought him home. Please!!!
It's natural for the baby guinea pig to be scared in a new place. In this case, you need to approach the baby guinea pig by inviting him to communicate slowly and also give the baby guinea pig healthy food. Surely, shortly, the Peruvian baby guinea pig will not be afraid and will get closer to you.:D
Don't PANIC! The baby guinea pig is scared and not used to the new place.
