Summary
Walnut shell litter is biodegradable, lightweight, and has a texture similar to clay that most cats accept easily. It's one of the few natural litters that clumps well enough for automatic litter boxes.
Made from soybean byproducts, tofu litter clumps firmly, is nearly odorless, flushable, and produces zero dust. Reddit users who've switched report their homes smell like nothing at all.

Our take
Walnut litter is the best bridge between natural and conventional — it looks and feels like clay to your cat, clumps decently, and is actually biodegradable. It's the easiest natural litter to transition a clay-addicted cat onto.
Tofu litter is the most underrated natural option — it clumps like clay, flushes down the toilet, and produces zero dust. If you're willing to pay a premium, it's arguably the best all-around natural litter experience.
