Has anyone tried one of the automatic liter disposal boxes? I am looking to see any problems people have had, or if they even work.
My mother is considering one for about $100. She has a cat that does not cover his stuff when he goes. As a result I sits on top until the other cat uses the little box, then this other cat covers both of their stuff. My mother thinks that with an automatic box, once the cat goes it will take care of it for him.

I looked in the FAQ's but I could not find anything in regards to this.
