I ordered this for our kitty to prevent the odor that most cat boxes allow. I thought the cover would be perfect, plus I like the round size.  We are happy with the outcome, but the only comment I would make is that it's a little small and our girl cat has a bit of trouble manuvering herself once inside. The result is gravel outside the opening when she tries covering up after use.  Over all it works well and is not an eyesore like so many other boxes.
