After much online research and many mixed reviews on this product I was a on a mission to find the perfect covered litter box for four 8 week old kittens that I'm currently fostering. They had been using a basic open litter box. It was becoming much too time consuming always having to sweep the scattered litter around and in their crate. I wanted to find something compact to put inside their crate that is covered, and that didn't take up a lot of space. A lot of the covered litter boxes are on the larger side, because of the booda domes shape this is not. As far as keeping the litter contained, so far so good. I'd say there's significantly way less litter outside of the booda dome. Most importantly the kittens seem to love it too. However I have 3 adult cats that are on the larger side, and don't think I would purchase this item for them. I would however recommend this for kittens or a smaller cat. If I only I had purchased this product sooner.
