March 2009. The biodegradable World's Best Cat Litter is made from pellets of ground corn, so it can be flushed down the toilet or recycled as mulch. Unlike another recommended biodegradable cat litter, Feline Pine (*est. $12 for 20 lbs.), World's Best Cat Litter clumps on contact with urine, a big selling point with some reviewers since it makes the litter box easier to clean. However, owners and experts point out that this litter is more expensive than Feline Pine, and it can be dusty. As with other large-pellet cat litters, some cats simply won't take to its texture and will refuse to use the litter box.
