I have a guinea pig named Roscoe. When I woke up this morning she was acting really strange. She makes unusual noises, can't see right, walks in circles, won't eat but chews everything, won't drink. It appears she is only breathing on one side. Her mouth won't shut all the way. I feel awful because I don't have enough money to take her to the vet. Does anyone have any ideas or suggestions? I feel so bad for her.
