World's Best Cat Litter

Biodegradable clumping cat litter

Pros
  • Biodegradable (flushable, recyclable)
  • Appropriate for kittens
  • Clumping
Cons
  • Premium price
  • Can be dusty
  • Some cats dislike the texture

Bottom line

World's Best Cat Litter receives more recommendations from professionals and owners than any other cat litter we've spotted. This biodegradable cat litter clumps with urine and does a great job of controlling odors. The larger-than-usual pellets (made of ground corn) are safe for kittens to use, though some cats may dislike their texture. On the downside, reviews say that this cat litter can be dusty, and it's relatively expensive.

Effectiveness

A great organic clumping litter ... if your cat uses it. World's Best Cat Litter is a biodegradable cat litter that clumps on contact with urine, a big selling point with some reviewers since it makes the little box easier to clean. Caroline Golon, who writes at pet blog Catster.com, says it clumps "extremely well." She also calls it a "power player" when it comes to controlling odors. However, its pellets are larger in size than those found in most other cat litters; many experts and owners warn that some cats simply won't take to its texture and may refuse to use the litter box. There have also been some reports that this litter can be a bit dusty at times.

Environmental factors

Corn-based biodegradability. World's Best Cat Litter is a flushable cat litter, and since it's made from pellets of ground corn it can be recycled for mulch. Lisa A. Pierson, who reviews the litter at CatInfo.org, notes corn-based litters can have a "hypoallergenic nature," and doesn't recommend it for cats with asthma because it can be a bit dusty. Blogger Daniela Caride gives World's Best Cat Litter a rating of Excellent, but also notes there is always a possibility of Aflatoxin contamination in corn- and wheat-based litters. Based on Caride's correspondence with the manufacturer, this shouldn't be an issue if wastes are removed routinely.

Value

Very, very expensive. Judging from reviews, the biggest downside to World's Best Cat Litter is the price. One 28-pound bag is $30 -- about twice as expensive as your typical brand of cat litter. Many owners posting at Amazon.com admit that it's pricey, but say you get what you pay for. If you're looking for an all-natural litter that's appropriate for kittens -- and you don't mind dealing with a messier litter box -- the non-clumping Feline Pine (Est. $12 for 20 lbs.) by Nature's Earth is a better value.

Christie Keith recommends World's Best Cat Litter in a thorough article for the San Francisco Chronicle, with one caveat. "The main drawback," she writes, "is that, while made of corn and entirely natural, it must also contain diamond dust or something, because it's extremely expensive."
