The collaboration of the high-performance cat litter pad with the upgraded cylinder prevents urine leakage within the automatic cat litter box. The waterproof surface prevents liquid from seeping through to the bottom, maintaining a clean bottom for the litter box. The anti-stick feature guarantees that waste won't adhere to the surface, making cleanup a breeze. Additionally, its scratch-resistant properties ensure a long-lasting use. The upgraded elastic edge of the litter pad provides a quick and easy setup experience.
