The Beeztees litter tray mat is suitable for the Nestor, Nestor Jumbo and Nestor Corner litter trays. The anti-slip finish on the underside prevents the mat from slipping. The mat prevents your cat from spreading cat litter granules or wood pellets around the house after visiting the litter tray. Simply place the mat in front of the entrance to the litter tray so that your cat always has to walk over the mat. A nice detail is the picture of a cat's paw on the mat.
