PawHalo Natural Tofu
& Wood Fiber Cat Litter
5.5 lb · $18.99 · Up to 21 days odor control
Food-Grade Tofu Fiber
Primary ingredient Food-safeWe source the same food-grade soy protein used in human tofu production. It's been proven safe for food contact — so it's definitely safe for your cat to walk on and groom from their paws. The fine fiber structure absorbs moisture on contact, locks in liquid, and forms tight clumps that don't crumble.
Why it's here
Fast absorption, firm clumps, and zero harmful dust — everything clay tries to do, better, with an ingredient you could technically eat.
Sustainably Sourced Wood Fiber
FSC-certifiedOur wood pellets come from FSC-certified sawmill byproduct — wood that would otherwise be discarded. Blended with tofu fiber, they add structural strength and a subtle, natural pine-like scent. Every bag uses raw material that was already cut; no trees fall for PawHalo.
Why it's here
Adds clump integrity and a natural woody scent without synthetic fragrance. The byproduct sourcing means this is genuinely zero-impact — the wood was already cut.
Green Tea Extract
NaturalConcentrated green tea catechins are natural odor neutralizers — they bind to ammonia and sulfur compounds at a molecular level rather than just masking them with fragrance. Green tea extract is also naturally antimicrobial, inhibiting the bacteria that create odor in the first place.
Why it's here
Real odor elimination, not perfume. The catechins neutralize the source compounds — your box doesn't smell because there's nothing to smell, not because we added a stronger scent on top.
Natural Baking Soda
Natural Food-safeSodium bicarbonate (the same baking soda in your pantry) is a proven pH buffer and odor neutralizer. It absorbs acidic odor compounds on contact and creates an environment where odor-causing bacteria struggle to thrive. It's also completely safe if your cat grooms trace amounts from their paws.
Why it's here
Works alongside green tea extract for double-layer odor control — one neutralizes at the molecular level, one buffers pH. Together they last up to 21 days.
PawCute Tofu Cat Litter
with Probiotic & Activated Carbon
16 lb + Free Toy · $34.99 · Advanced odor control
Food-Grade Tofu Fiber
Primary ingredient Food-safeThe same food-grade soy protein base as our Natural formula — proven safe, ultra-fast clumping, and 99% dust-free. The PawCute formula uses a slightly finer tofu fiber grind for an even softer texture underfoot, which cats with sensitive paws particularly love.
Why it's here
The backbone of both formulas. Food-safe, fast-clumping, and the only base ingredient that's biodegradable and flushable.
Probiotic Culture
Signature ingredientPawCute's signature addition: a live probiotic culture (Bacillus subtilis strain) that colonizes the litter box environment and actively competes with odor-causing bacteria for resources. Unlike green tea extract which neutralizes existing odor, probiotics change the microbiome of the box itself — meaning less odor is produced in the first place, not just absorbed after the fact.
Why it's here
Multi-cat households and cats with stronger odors need more than absorption — they need the litter box environment itself to work against odor. Probiotics are the only approach that does this at a biological level.
Activated Carbon
Food-gradePharmaceutical-grade activated carbon (the same used in medical detoxification) has a porous surface area so vast that a single gram can absorb odor molecules from hundreds of square feet. In PawCute, it acts as a rapid-response odor trap — catching volatile compounds the moment they're released, before probiotics can consume them. The combination is exceptionally powerful for multi-cat homes.
Why it's here
Immediate odor capture while the probiotic culture handles long-term odor production. The two work differently and are additive — activated carbon traps; probiotics outcompete.
Natural Baking Soda
Natural Food-safeIn the PawCute formula, baking soda plays a pH-balancing support role — creating conditions where the probiotic culture thrives and odor-causing bacteria don't. At the right pH, both the probiotics and activated carbon perform optimally.
Why it's here
pH optimization for the probiotic culture — a support ingredient that makes the signature ingredients work better together.
What we left out
(on purpose)
Sodium bentonite clay
Strip-mined, non-renewable, and the source of harmful silica dust your cat breathes every day.
Silica gel / crystalline silica
Classified as a Group 1 carcinogen by the WHO when inhaled as dust. Not in any PawHalo formula.
Synthetic fragrances
Artificial perfumes mask odor rather than eliminate it — and introduce unknown chemical compounds into your cat's environment.
Chemical dyes or colorants
Added for aesthetics only. Zero functional benefit, potential irritant for sensitive cats.
Parabens or preservatives
Our formulas are shelf-stable without synthetic preservatives — no need for them.
SLS / SDS
Surfactants with no place in cat litter. Every ingredient in PawHalo is there for a reason — and we can name that reason.
Clean ingredients.
Happy cat.
Now that you know what's in it, choose the formula that's right for your cat.
