my guinea pig keeps biting me, he isn’t very old however he will do this anytime I have him out. I don’t even have to be holding him for him to do this, he won’t just bite my fingers. He has bit my knees and my ankle bones. He has broke my skin slightly as well. It isn’t because he needs to urinate or because he can smell food because he has bit me in places other than my hands. I also don’t have to be holding him. He will just come up to me and bite me. Any suggestions or tips would really help
