I honestly had thought he was just biting at stray hair from his beard that would get in his line of vision. I didn't even think it could have anything to do with his shunt. I'm starting to get angry at his former owners for not having it checked out. Here this poor little guy just gets laughed at for being "retarded" (thats how old owner referrred to him) and it could actually be an underlying problem from his disease.
