Some cats prefer to have their litter changed gradually. Start with only a third of World's Best Cat Litter™ added to your current litter. Then, once your cat is more familiar with it, change to two-thirds. After that, use only World's Best Cat Litter.
Always wash your hands thoroughly after handling used cat litter, as cat feces may contain Toxoplasma gondii—a parasite that can cause toxoplasmosis. Pregnant or nursing women, as well as children and anyone with a weakened immune system, should avoid handling used cat litter. Always handle litter in a ventilated area to avoid inhalation. Keep contents and packaging out of reach of children and pets. Seek medical help in case of accidental ingestion.
