Nugi Plus Indoor Dog Training Toilet, Litter Tray Medium with Reusable Pee Pad ( Size: 21 x 18.5 x 1.6 in ) The plastic NUGI Indoor Dog Litter and Pads are a unique solution, that provide a neat and efficient answer to your dog's indoor toilet needs. With NUGI you can say goodbye to messy paws, urine smells and mountains of wet newspaper or pee pads and hello to a cleaner home and environment. The ingenious design of the NUGI Tray includes rubber feet to prevent any slipping, a grate that locks securely into place ensuring your dog will benefit from dry paws, but remain unable to get at the urine pad to rip it up or chew on. Poop can settle on the grate and be removed at your convenience. The Tray comes equipped with a free Pee Pad to absorb the urine. Rather than needing to be disposed of, simply rinse clean and stick to a wall to dry before reusing over 50 times! A minimal percentage of urine is left on the pad which encourages your pet to return and reuse the Nugi Tray The Tray is 18.5 x 21.5 x 1.6"inch (47.5 x 54.5 x 3.5cm), 1 Litter Tray + 1 Hygienic Mesh Top + 1 Washable Pee Pad
