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 dehydrate waste on contact while any runoff falls through the grate under the litter and onto the absorbent, leak-proof 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.
