I am disappointed. It’s just cheap particle board and nothing to prevent moisture from swelling up the particles. It was wrecked in one night. My male cat clearly requires a high sided litter box or a box with a lid. This cabinet does not fit a lidded litter box. I a purchased rubberized mat to keep moisture off the cabinet floor and used a high sided litter box. Still had leakage over the side which has ruined the cabinet. Furthermore, the rubberized mat makes it very difficult to get the litter box in and out to clean. 
Either design the cabinet to fit a lidded litter boxes or design a lidded litter box to go with the cabinet. Better yet, make the inside of the cabinet with a moisture proof coating or laminate. I was willing to splurge on this cabinet thinking it had actually been designed as a “litter box enclosure.” Ive now spent more money trying to fix the flaws. Frustrating.
