We needed a cat box for our sunroom, and this was a more attractive solution than any others I found. Top can be removed easily for cleaning. Need to match edge of top and bottom halves when putting the top back on, but it's not difficult. We heard from a cat behaviorist that when one has more than one cat, they are less likely to have accidents or do intentional marking when there are multiple boxes in the house. When we moved, we put in 3 cat boxes and it has worked very well, but we only had 2 discreet spots, so we needed a camouflaged box for the sunroom.
