Housetraining Starter Kit with Gel Pads - Great for Puppies"Paw Trax Training Kit" includes a two piece tray with non-skid feet to prevent scratches, and seven easy-change pads to get you started. The try holds the pad in place that so many puppies otherwise love to thrash around for fun. The super absorbent gel in the training pad locks in moisture and odor allowing the surface to dry in seconds, preventing your dog from tracking urine off the pad onto carpets or floors. Each pad holds up to two quarts of liquid. (G) Tray measures: 25" x 18" x 1.5". 50-Pack Paw Trax refills available
