Fresh Step Cat Litter with Baking Soda 21-lb bag

Fresh Step Clay Litter has a super-absorbent formula that continues to neutralize odor between uses. That's because the patented formula actually fights the growth of odor-causing bacteria in the litter – to stop ammonia odor before it starts. The result: your litter box stays fresher longer. And, only Fresh Step is made of a rare high-quality clay that is both super absorbent and super lightweight! When your cat steps, scratches or uses the litter box, the patented odor-control system in Fresh Step is activated immediately.
