This pet tray/food bowl set uses a combination of powerful rare-earth magnets, a melamine tray, and steel enamel bowls for extra stability. How does it work? The food and water bowls magnetically snap into specially designed recessed pockets, locking them into place. The bottom of the tray has four non-slip rubber feet securely attached, preventing tray movement. The tray also has a half-inch lip along the outer edge that prevents food or water from reaching your floors. This pet food tray eliminates the slide problem of both the food tray and bowls!
