He attacks light reflections on the wall in a single bound. Joe, it is the funniest thing in the world to see. He sits on the night stand and the shaft of light coming in through the blinds reflects on the wall right at the cieling and with clouds and the like, the shadow appears to be moving. He will launch himslf straight up in the air. It is just about the most hysterical thing I have ever seen any cat do. I'm so worried he's going to break a leg doing this, because he slides down the wall all the way from the cieling and he looks like Sylvester when he does it. But, he won't do it if your watching. You have to act like your not interested in his plight for him to jump. I'll have friends over and we'll be in the LR and we can her "SSSHHHHHHHHHHHH - BONK" as he slides down the wall and lands onb the floor. It is just too funny.
