We chose this litter box because of the high sides, so our cats couldn’t kick litter out of their box. We absolutely love the high sides as it has helped greatly. The part I don’t love, and we really had no way of knowing until we used it in person, is the design of the inside bottom of the litter box itself. It has a ridge around the edge where all of the litter gets kicked, and there is also a strange corner at the front where used litter gets stuck. Just takes a little longer having to clean it because of the ridge and it’s rather annoying. Overall it’s a decent litter box, mainly because of the sides, however I probably would not purchase again because of the inside bottom of the box itself.
