This unique blend of naturally occurring minerals absorbs odor-causing enzymes on contact, locking in and stopping odors before they start. Which means your litter box stays fresher, longer. Pinch yourself! Right back at you, mother earth. Each jug of cat's pride fresh & light weighs less than other competing scoopable brands, requiring fewer trucks to ship the same amount of cat litter. This means less fuel is used to transport the same amount of fresh & light litter to your store. And using less fuel is a good thing these days. So breathe a sigh of relief!
