Well, if its not illegal, I would try leaving a live, rat pup (with eyes closed still) in with him overnight and just leave him be in a dark quite room. Chances are it will be gone. Try this after you have let him settle in for a week or two with no handling, so he isn't stressed out. Also make sure he has two secure, snug hides. Sometimes it takes eating live a few times to get them going. Good luck with your baby!
