My cat loves to sling his litter when he is covering things up. In the old litter box I would have the smelly litter 12 feet from the litter box. I was always having to sweep the floor. I purchased the Dome on the recommendation of other Cat owners, and I am so glad I did. He still slings but now almost every granule is in the box. Really about the only granules that I find on the floor are the ones his paws track out. I highly recommend this if your cat likes to sling his/her litter. And it's just as sturdy built as the CatGenie itself.
