I really like the top entry on this litter box. My cats used it right away (they are used to the standard covered box). I love that it has the grooved top part to catch any extra litter that the cats have on their paws. The amount of litter I usually have on the floor is now very little. It is very easy to keep clean. It also comes with a scoop that matches the color of the box. This is a great litter box that really helps minimize the amount of litter that usually gets on the floor. I would definitely recommend this product to any cat owner.
