Is it really flushable?

Yes, the litter is marketed as flushable. Flush one or two small scooped clumps at a time and check local rules, since septic systems and older plumbing may not handle it.

How does it compare with clay clumping litter?

It clumps as firmly as clay and produces much less dust. It is lighter and flushable, but it tracks more and some cats prefer clay's texture.

How many cats does one bag serve?

The 28 lb bag lasts roughly a month for one cat with daily scooping. Multi-cat homes use it faster, so plan on more frequent changes.

Does it control odor well?

Yes, when scooped daily. Odor control is weaker if waste sits, so multi-cat households should scoop twice a day.

Will my cat accept the corn litter?

Many cats switch without trouble, but some resist the change. Mix it with the old litter over a week or two to ease the transition.

Whole-kernel corn litter in a two-pack of 28 lb bags. It contains no clay, silica dust or added fragrance.

Our take on the World's Best Cat Litter Clumping

World's Best Cat Litter Clumping is a plant-based litter made from whole-kernel corn. It clumps hard, scoops cleanly and is flushable, which sets it apart from most clay litters. It suits owners who want a natural litter with low dust and easy odor control. Against clay rivals it is lighter and flushable, but it costs more per pound and some cats take time to accept the corn texture.
