New. Open box. By Catch. Dimensions: 29 1/2” x 22”.After using the litter box, your cat steps on the mat. Instead of tracking the kitty litter, the kitty litter falls through the honeycomb top layer on to the solid bottom layer. The 2 layers attack to each other with Velcro. To get rid of the excess litter all that you have to do is separate the 2 pieces and dump the litter that is on the bottom layer in the trash or back into the litter box. The litter mat is waterproof, easy to clean, non-toxic, non-slip, and very durable. Color is like a grey blue.
