A great product.  In fact I ordered two of these, one for the main floor kitty box and one for the upstairs kitty box.  The texture and size of the mat does a really good job of holding the litter that the cats get on their paws as they exit the box. You will be surprised how much litter is no longer spread throughout the house.  We shake out the mats each time we clean the litter box. Periodically we hose off the mats letting them dry before putting back under the boxes. Like the neutral color as well.
