CatsReally Great Cat Litter Review: Is Tofu Litter Worth Switching To?
Clay litter tracks everywhere, weighs a ton, and can't be flushed. We looked at whether Tuft & Paw's tofu-based litter actually solves those problems or just trades them for new ones.
Published October 15, 2026
Clumping clay litter has three well-known downsides: it's heavy to carry, it tracks across the house no matter what mat you buy, and it should never go down a toilet. Plant-based litters made from tofu, corn, or walnut have been marketed as the fix for years, with mixed results — some clump poorly, some smell worse than clay once wet, and "flushable" claims don't always hold up to how most home plumbing actually handles it. Really Great Cat Litter is Tuft & Paw's entry in that category, and it's specific enough about its own limitations that it's worth a closer look.
Tuft & Paw Really Great Cat Litter (Tofu)
At $29 a bag (or less per bag on a multi-pack), it's priced like a premium litter — but the combination of low dust, lighter bags, and real flushability for small amounts is a genuine quality-of-life upgrade over clay for most apartment and multi-cat households.
- ✓ Clumps and flushes in small quantities, unlike clay litter
- ✓ 99% dust-free — noticeably less airborne dust than clumping clay
- ✓ 58% lighter per bag than clay, easier to carry and pour
- ✓ Charcoal and lavender scent options, plus unscented
- ✕ Costs more per bag than basic clay litter
- ✕ Most cats take 2-3 weeks to fully transition from clay or crystal litter
- ✕ Flushability depends on your home's plumbing and local sewer rules
What It Actually Is
It's a clumping, tofu-based litter sold in 9.25 lb bags — about 58% lighter than the equivalent clay bag — available unscented, with activated charcoal, or lightly scented with lavender. One bag is sized to last roughly a month for one cat, which is in line with how most clumping litters are sized.
The Claims That Matter: Dust, Tracking, and Flushability
The 99%-dust-free claim is the one that actually changes day-to-day use — a lot of clay litter's mess comes from fine dust kicked up during digging and scooping, not just tracked granules, and a genuinely low-dust formula is noticeably different to live with. The low-tracking claim held up reasonably well in practice, though "low" is relative to clay, not zero. On flushability: tofu litter can be broken down by most home plumbing in small quantities, but this depends on your specific plumbing and local sewer rules, so it's worth checking before making it a daily habit rather than assuming the package claim applies universally.
The Honest Downsides
It costs more per bag than basic clay litter, and most cats need 2-3 weeks to fully transition from clay or crystal litter — this isn't a same-day swap for a cat set in its ways. If your cat is particularly particular about litter texture, expect an adjustment period rather than an instant switch.
Our pick
For an owner who's tired of clay dust and the weight of hauling litter bags, this is a legitimate upgrade rather than a marketing-only "natural" litter — the dust reduction in particular is a real, noticeable difference. Budget for a gradual transition rather than a cold swap, and treat the flushable claim as a bonus for small amounts rather than your primary disposal method.
