Would seem he has to be in a small room for quite some time. Does he have cheap toys, a window to see out of, a scratching post, etc so he isn't completely bored? Everything has to be cleaned meticulously all the time of course and/or thrown out but at least a few toys would help his boredom.
Do you go in to play with him? Is there any way you could find some paper scrubs like a doctor uses and rubber gloves? That way you could spend a little time with him playing and socializing. I feel bad for the little one.
