Cat Litter Types Compared: Clay, Tofu, Mixed, and Crystal

Clay clumps tightly and feels closest to natural substrate, giving the highest acceptance, but it is heavy, tracks, and cannot be flushed. Tofu litter is light and low-dust and some brands allow small flushes, yet it molds in humid seasons and needs full changes. Mixed litter blends the strengths and is a balanced home default.

Crystal litter absorbs strongly with infrequent changes but needs stirring and some cats reject the feel; pine pellets require a sifting two-layer box and diligent cleaning. Avoid heavily scented products for kittens; fragrance can irritate airways and cause refusal.

Selection order: confirm the cat accepts the texture first, then compare dust and odor control, then monthly cost. Transition by mixing old and new litter, and revert immediately if the cat holds urine or eliminates outside the box within a week.
