Pidan Original Bentonite Cat Litter is a multi-purpose clumping litter made from beneficial clay. Before any liquid reaches the litter box base, the clay forms tight clumps, preventing crumbling or sticky litter. It's also fragrance-free and contains activated charcoal particles that are 99 percent dust-free and aid in odour reduction. This litter is naturally fast-clumping, forming clumps in just 3 seconds, a result of being produced with sodium bentonite and sourced directly from natural mineral clay.
