Threelayer system with drip tray The dog artificial grass mat features a threelayer design. Urine seeps through the grass and travels along an angled tray into the collection container, keeping the surface dry and reducing mess. It serves as a practical alternative to puppy pee stones. Potty training support Helps with indoor housetraining by naturally distributing urine on the grass mat. The setup is ideal when you come home late and need a potty option inside, or when outdoor access is limited by illness or bad weather.
