The Premier Pet Dual-Fresh Litter Box System keeps your cat happy with a fresh and clean smelling litter box. This system uses both premium crystal litter and a pee pad to control odor. The crystals absorb moisture and dehydrates waste on contact while any runoff falls through the grate under the litter and onto the absorbent, leakproof pee pad. Simply use the included scoop to remove solid waste and change the litter and pee pad as needed. The lid with an anti-tracking step helps keep the litter box area clean as well. Keep your home smelling fresh with this all-in-one litter box system.
