Recognizing the need to reinvent cat litter, Muscatine, Iowa-based GPC Pet Products has come up with the World’s Best Cat Litter. In attempting to live up to its name, the product is a biodegradable, septic-safe and all-natural product made from whole-kernel corn. It also uses no synthetic chemicals, clays or perfumes. An eight-pound bag retails for a suggested $7.99. To find out more, visit www.worldsbestcatlitter.com.
