This is such a terrific idea. I have two cats and the CatGenie has had a lot of use. There was always a small trail of litter near the box that I had to clean up each day. This mat is perfect, because it contains the granules as the cats exit the litter box, and makes them even more recycleable because the mat can be folded into a funnel to put the granules can be put back into the GatGenie. I wish I had purchased this when we did the initial set up, it's a time saver.
