So, Wally has a thing for boxes, he finds them, sleeps in them, plays...whatever cats do. He also likes to eat them. The cardboard lid that he has been playing with since I moved in has become a chew toy, which means there is cardboard all over my floor, so I bought the little monsters a cat house in the form of a square cloth thing with three big holes in it, one of my better investments because they are in love. Wally was lying in it during lunch and they had it turned so that one of the holes was facing up, which is the one Panda chose to jump through to attack him...great fun followed.
