【HIGH QUALITY MATERIAL】Our dog pad holder trays are made of high-quality, odorless PP material that is robust and resistant to deformation and breakage. There are four non-slip pads at the bottom of the small dog litter box that protect the floor from scratches and hold the tray in place so that even active pets don't have to worry about tipping and damage. This is a long lasting solution for your dog's urine tray needs. 【KEEP CLEAN AND TIDY】The grille is easy to pull up to clean and change the pad. The base tray accommodates the grid tray with a cushion placed at the bottom. When your dog goes to the toilet, the urine goes through the grid, through the holes in the grid tray, and to the bottom of the base tray. The height between the grid and the base tray is up to 2 cm and can be kept away from urine. Provide a healthy living scene for your pet while giving you a cleaner home scene. 【PREVENT CHEWING】The puppy potty training tray is integrated with the grille, which is easy to pull up and place the urine pad. Closing it will prevent the puppy from tearing the pee pad and keep the floor in the house clean and tidy. A closed pad holder can save you from puppy training shenanigans. No more ripping pee pads! The low entrance design of the pet potty training tray makes it easy for your cute pets to get in and out, even for elderly dogs with injuries or mobility problems.
