Made of stain and odour resistant material, it has a raised grid to help keep pets' paws clean and prevent them from spreading waste throughout the cage and the rest of their areas. The grid is removable, making it easy to clean. Two locks allow the corner tray to easily attach to all wire cages and remain stable. So your pet will be completely secure while visiting his favourite corner. The Deluxe Corner Tray is designed with a fairly high back wall, preventing it from spilling all around the cage and the rest of your pet's area. A convenient and practical idea.
