The Dog Gone Smart Cat Litter Mat magically soaks up water, mud and dirt with the wicking power of thousands of microfiber strands keeping your floor clean and dry. The mats have a GSM absorption rate of 3000; this advanced wicking power absorption rate is considerably higher than any of the competition that has GSM's from 900 to 1500. The only mats to use the heavy "Gripper Non-Skid" backing on the bottom of the mat, this prevents skidding and movement of the mat which is a major concern for consumers. None of the "knock off" litter mats have this exclusive non-skid backing. They are constructed with double basting and even stitching for rugged durability and long lasting use. The microfiber mat will dry five times faster than ordinary mats and is machine washable for easy cleaning. Dog Gone Smart is a small family owned business located in Norwalk, CT and is the leader in stay clean technologies for pets in 42 countries. We donate a percentage of our profits to animal shelters and animal rescue groups around the USA.
