As one other reviewer this very small litter box might be good to train a kitten with but it's not really good for adult cats. You could teach a kitten to face the right direction, not pee off the side or on the holes in the rim. My cats don't deficate in it only pee when they make it in there.I bought it as possible transition to toilet training for some of my cats. If you buy this despite my warning you can use plastic shopping bags to line the container with to make cleaning easier. Also I have 13 lb cat that was the first to use it and it is stable enough to hold him.
