Hi! I just rescued a guinea pig today as a friend for my other one. The people who had her were allergic so they had to get rid of their three. The one I got is four months old. The two other guinea pigs she lived with previously, weren't very nice to her and pulled some of her hair out. She has a large scab on her cheek that looks like it's almost started to heal itself. The other one is around the bottom of her eye. Could that be an upper respiratory infection? I think the woman who owned her said they took her to the vet and they said she was healthy. Should I talk to my dad about taking her to the vet just to make sure everything is okay? I checked for mites and lice and she doesn't have either. She liked the massage of me looking through her hair though. She's been very social and happy since she came home (pop-corning all over her cage). The two are in separate cages for a week so they can talk and get to know each other. Any advice/suggestions? Thanks!!
