World’s Best Cat Litter uses a patented process to compress corn into super-absorbent granules, delivering outstanding odor control and a cleaner litter box with less hassle and less litter. Unlike clay litter, World’s Best Cat Litter doesn’t stick to the sides or bottom of the box, so there’s no more chiseling and scraping. Our litter is lightweight and long lasting, with no silica dust. It’s made from sustainably grown corn (not mined or drilled like clay litter), with no added chemicals, so it’s pet, people and planet friendly. And, World’s Best Cat Litter is tested and proven flushable* and septic safe, so you can scoop and flush without worrying about clogging the pipes!
