If your kitty is finicky with litter, look no further! This Litter has no added perfumes or fragrances that could be offensive to cats. It clumps on contact by immediately absorbing urine. This quick clumping action traps the odor-causing bacteria, and odors disappear. Clumps will continue to harden and dry until all liquid is absorbed. SmartCat All Natural Litter works great on fecal odors as well. Your litter box will stay clean and odor free.
