World’s Best Cat Litter’s GiveLitter program donated 30,000 lbs. of litter to two animal shelters. Cat owners voted on the company’s website to donate litter to the Idaho Humane Society and The Progressive Animal Welfare Society (PAWS). For each vote, World’s Best donated one pound of litter to the chosen charity. Each charity received 15,000 lbs. of all-natural litter to support their adoption efforts.
