hello, gracie my 2 year guinea pig had a scab come off on her side we went to the vet he said it was ok and he gave us some medicine and check up on her. today at night i heard a loud harming squeak nothing like i have heard befor and her heart was racing when i came over i looked at her scab and it was not healed it came off about a week ago and she has been licking on it she seems normal no hair loss no strange activity? after that squeak she seemed to be normal. is this normal?
