Heritage & History
World's Best Cat Litter began in 1996, when a group of scientists set out to create the best clumping cat litter possible and developed a process that turns natural corn into litter that is safe for cats and free of harmful chemicals, artificial perfumes, and clay dust.
The brand, produced by Kent Pet Group, a subsidiary of Kent Corporation, has grown to ten formulas sold online and in major retailers including Target and Walmart, and has donated more than nine million pounds of litter to rescue cats through its GiveLitter program.
Made in Muscatine, Iowa
World's Best Cat Litter is produced by Kent Pet Group in Muscatine, Iowa, using a patented process that compresses whole-kernel corn grown in the U.S. into super-absorbent, clumping granules.
