I ordered the XL version of this to fit a Scoop Free self-cleaning litter box. I needed to find a way to put one upstairs in my office. This seemed like a good way to do so without the cats scattering litter everywhere. 

I'd previously used the cover that came with the boxes but, as my kittens grew too big, they stopped using the covered one. I guessed because the cover was too low. 

This sounded like it had plenty of head clearance, and I left the drawer out to leave even more. 

This was easy to assemble. It seems quite sturdy for its purpose. I haven't been able to adjust the doors so they close equally, but once the litter box was in, I could place that so it solved the problem. 

One of my young male cats was in it before I could get the doors closed, and his brother was in line to use it next, lol. Hopefully my older female will like it, too, since that room is her hangout.
