I have a small space, and I didn't want a standard catbox showing. I was also annoyed by all the litter my cat was tracking out. This thing is nice because it definitely cuts down on tracking, keeps the smell in, and is discreet. I didn't have any trouble finding the right size litter box. I think I'm going to get an air freshener and attach it to the inside of the unit as well. My cat doesn't seem to mind it, but he's pretty small. If your cat is really big it might be a little uncomfortable. I screwed up putting it together at one point, but that was definitely my oversight. The directions are pretty clear, but it might have been a little easier at a couple points with an extra set of hands. Overall, just what I was looking for. The only thing that could make it better would be if it was soundproof!!
