effectively stops the release of cat litter particles from the litter box. Litter transfer from the litter box is greatly decreased by the unique shape of the particles, which decreases adherence to hair and paws. The absorbent power of technically refined active wood fibers, which can effectively absorb and trap urine, fluids, and odors deep within—up to seven times their weight—is another feature of Cat's Best Smart Pellets. Consequently, it is possible to keep Cat's Best Smart Pellets in the litter tray for up to three weeks before replacing them entirely.
