Jasper is OCD the medicated kind! we have 3 dogs and 8 cats, birds guinea pigs, snakes and rats. Ok so maybe the cages don't really need to be cleaned quite so often....but since he HAS to do it, you think I am going to complain??? It works for vacuuming too... I look at a spot on the floor and say Oh my, what IS THAT?? then start to walk over and he can't help it he just has to vacuum the whole room. OOPs did I just let out a secret?
