- Compatible with over 95% of cat litter types; upper layer has through-holes for litter to pass through, while the waterproof lower layer traps litter, urine, and dirt. - Dual-layer design: upper layer with hexagonal holes to prevent litter scattering and provide a soft, non-scratch surface; lower layer seals in litter and is anti-slip for safety. - Made from high-elastic EVA material, which is soft, washable, and breathable—ideal for cats who prefer a gentle touch.
