Thanks, heh. Dan just put silicone on the top of the door flap to it won't make as much noise when John decides to bat it around for minutes on end.
He is also trying to shove John through the door head first so he will stop trying to open it with his paw.
The funniest part is that before batting at the door flap, John will sit there and stare at the doorknob, trying to get me to notice him and open the entire door just for him!
