It took a while to assemble, but it is worth it. 

We did not use the center divider because the litter tray would not have fitted in. Our two cats happily use this new box. I lined the floor of the box and the walls with some of the cardboard that the item came in.

It does the job - it looks like a piece of furniture and not a litter box. It also serves as a window seat for the cats - we put a coffee colored mat on the top.
