We have tried everything. This works perfect for my cat litter box. I have a very large cat litter box and cat who throws things all over. This is cut down on my work tremendously. And I'm sure my cat appreciates not having gravel in between his toes. Thank you oh and for the people that said that it had a horrible smell I put it outside and hang it on the banister for half an hour when I first took it out of the box and the smell was completely gone never smelled it again and laid completely flat.
