Dual-Layer Design: Our dual-layer honeycomb mat traps litter, making clean-up a breeze. Simply lift the mat and watch the litter fall through. Then, dump it back in for reuse. Non-Slip & Waterproof: The bottom layer is both slip-resistant and waterproof, preventing leaks and making it easy to move. Your cat's claws will be protected and they'll love the feel of walking on it.
