The litter containment enclosure is poorly made. The door magnets aren't strong enough to keep the doors closed, so I had to use tape. There are so many gaps in the enclosure that when the cats miss their litter box, urine goes through the box to the floor. Loose litter gets caught in all the cracks. I flipped the box on it's side with the doors facing up, and that seemed to solve a couple of the problems listed above, plus it's easier to clean the litter box.
