The enclosure is really nice! We aren’t using it for litter but as a hidey hole for the cat to sit in and hang outeat his food. He loves enclosed spaces. The construction was decent. I actually broke part G while I was building it because I screwed a screw in tightly and the wood started breaking. You have to be a bit gentle as some of the pieces are fragile wood. but wayfair shipped me an extra peice. Overall, it looks really nice! I plan to put cat-safe plants on top of mine!
