Plant-based litters have become popular with owners who want an alternative to clay. World’s Best Cat Litter is made from whole-kernel corn and forms clumps like clay. This review looks at how it performs and what to consider, including questions about flushing and storage.
Bottom Line: World’s Best Cat Litter is a lightweight, clumping, corn-based litter that many owners like as an alternative to clay. It’s biodegradable and easy to carry. It costs more than clay, some cats dislike the texture, and flushing cat waste raises environmental concerns, so check local rules before flushing.
At a Glance

|---|---|

| Main ingredient | Whole-kernel corn |
| Scent | Unscented and scented options |

What It Is and How It Works
World’s Best uses whole-kernel corn, which absorbs liquid and clumps. It’s lighter than clay and biodegradable.
The company markets some formulas as flushable. However, cat feces can carry Toxoplasma gondii, a parasite that can survive water treatment and harm wildlife such as sea otters. Some local governments advise against flushing cat waste for this reason. Check your local rules and your plumbing type before flushing.
Because it’s made from corn, it should be stored in a dry place. Damp litter can grow mold. Some owners also report it attracts insects if stored poorly.

Litter Box Basics
Litter choice is only one part of good litter box habits. Feline behavior experts commonly recommend:
| Guideline | Why it matters |
|---|---|
| One box per cat, plus one extra | Reduces competition and accidents |
| Box about 1.5 times the cat’s body length | Gives room to turn and dig |
| Scoop at least once a day | Cats avoid dirty boxes |
| Unscented litter for most cats | Many cats dislike strong fragrances |
| Quiet, easy-to-reach locations | Cats avoid boxes near noisy appliances or in dead ends |
| About 2 to 3 inches of litter | Enough to dig without excess scatter |
If your cat suddenly stops using the box, a medical problem may be the cause. Urinary tract disease, kidney disease, diabetes and arthritis can all change litter box habits. See cat peeing outside the litter box and litter box basics.
