Get the clumping litter with outstanding odor control and a tight clumping ability. Smell less, clean less and buy less with the original choice for 2X longer-lasting performance than the leading US litter brand.

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. This 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!
