Excellent litter box. Cats love it and it seems easy to clean. I took the door off initially because they weren’t quite sure about that and I might just keep it off. There’s no litter spilling which is great. My only niggle is that there were no instructions about how to install the white piece and I think there might also be some kind of filter and that’s not intuitive either. Otherwise, an excellent addition for my flock of 13 cats.
