How to Choose the Right Cat Litter

1 Natural Litters: Plant, Paper, and Wood

Plant-based litter (such as tofu or corn litter) is made from soy or corn residue. Pros: essentially non-toxic if ingested, forms clumps, lightweight, eco-friendly, low dust, and flushable. Cons: in humid summer weather it breeds bacteria and parasites easily, and most products are imported and pricey.

Paper litter. Pros: strong liquid and odor absorption, does not clump, dust-free, flushable, less likely to be tracked out of the box, and low in chemicals. Cons: some varieties turn mushy when wet and need more frequent cleaning, and it is expensive.

Pine or wheat litter. Pros: almost no dust, strong absorption and deodorizing, more economical than clay or crystal, easy to clean, and flushable. Cons: it can breed bacteria in humid summers, is a bit costlier, and the wood scent puts off some cats, who then refuse to use it.

2 Mineral Litters: Bentonite and Crystal

Bentonite clay litter. Pros: highly absorbent, clumps well, moderate odor control, the best paw-feel of all litters, and good coverage. Cons: heavy with high usage; dust and tracking vary widely by brand and quality.

Crystal (silica) litter. Pros: low dust, good absorption and deodorizing, more economical than bentonite, simpler cleanup, and mid-range price. Cons: not flushable; some cats accidentally ingest it, which can be dangerous; and it creates secondary pollution.
