The assembly instructions were somewhat confusing, but manageable. The plastic riser pieces on the bottom were also too large, in my opinion. They raise the enclosure just high enough off the ground to get cat toys stuck underneath. I replaced them with small rubber grips instead. I've also been unable to get the doors aligned correctly, but they do close (there's just an uneven gap). Overall though, this serves its purpose: the litter box is hidden away, and the cat doesn't seem to mind.
