The pet park is the good solution for pet accident-free living. It prevents messy indoor accidents by giving your pet a place to go potty instead of on your floor or furniture. Its 3-stage protection keeps your home clean and odor-free. Your pet uses the synthetic grass mat to urinate. The elevated grid tray keeps the mat high above the liquid, which falls down into the collection tray in the base. Just empty the tray at the end of the day and wash in warm soapy water. The reusable surface mat rinses clean and stores easily to stay fresh and sanitary. Great for porches, patios, and balconies too. You can use it for potty-training your young pet, or to help your mature or special-needs dog. Meanwhile the additional grass mat makes you replace it easily.
