I recently bought a young rat from a pet store so that my other rat wouldn't be alone. When we bought the young rat, he was alone in the cage. Ever since we got him he seems to not be interested in playing or anything, all he does is sleep. Even out of his cage, he isn't interested in exploring- all he does is tuck his head under something and try to sleep. Keep in mind, he isn't a baby, but he IS pretty young. If someone could help me out and tell me what's going on with him, I'd really appreciate it.
