So Phresh Cat Litter Trapper Mat loosens and captures litter to keep paws and floors clean. This mat's special pattern gently brushes off litter from your cat's feet keeping litter contained to the litter box area. Easy-to-clean - simply shake, vacuum, or rinse the non-slip flexible rubber mat. Medium measures 15" x 23" and Large measures 24" x 30".
Periodically shake the mat outdoors or over a garbage can to remove loose litter. Clean the mat with soap and water. Where appropriate, you can rinse the mat outdoors with a hose to loosen any dried-on clusters.
