This is the best enclosed box I found on the market, hiding both the litter box and the food dishes.  We live in a condo and didn't want to see either of these in the laundry closet area. This unit works perfectly and looks stylish.  I added a photo of the inside so you can see how much room there is where the cat "lands" to dine in the upper level.
Excellent construction and all the hardware was enclosed. You will need two people and a drill to construct it.
