It sounds like he is rebelling against being shut up.  That's too bad.  I can understand it.  Have you tried bitter apple spray?  I suppose taje has the best idea.  I have never had to shut mine up like that because someone is there and I know it has to be hard to do it.  I'm sorry I can't suggest anything else.  Is there a room where you could put him that isn't carpeted that has windows?  Looking out seems to be their favorite pastime.  At least, that is my experience.
