I love watching my cats play and get into things. One would lay on a chair covered with a quilt and bat at everything that passed him by. The youngest used to jump on the fridge but he doesn't anymore. What he still does is sit on tables and experiement with the laws of gravity. He will push something to the edge and watch and fall and then find something else. I have banned him to the bathroom at night because he plays most of the night and he also needs special food and eats constantly but I can't let the other cats get at his food.
