Hello, everyone! My guinea pig is very unactive. I looked at several videos of guinea pigs and they are all so active. (I'm jealous.) He acts lethargic, but he has always been that way, since I got him as a baby. He is not sick and he recently went to the vet. The vet said he was a healthy little pig, exept we had to treat him for a very minor UTI infection. He is now healthy and happy. The only thing that I am not pleased with is how he is not active and just sits in his hut. Any advice would be apreciated!
