The instructions were not labeled very clearly. Additionally, they suggested that the build would take a half hour, and though I’m used to building furniture, this piece took about 75 minutes. 

That said, I am happy with the piece. It is a solid piece of furniture and the kitties were very interested in it right away. 

I would add that it would be more helpful if inside dimensions of the enclosure were added to the listing so that customers could verify that their existing litter boxes will fit—otherwise they will have to purchase a new one. I was in the situation of needing to purchase a new one.
