What Is Tofu Cat Litter?
Tofu cat litter is made from natural soybean fibre β specifically the pulp (okara) left over after tofu production. This bio-waste material is dried, compressed into pellets or granules, and sometimes mixed with cornstarch for enhanced clumping. The result is a lightweight, biodegradable litter that feels soft underfoot.
Key properties:
- Biodegradable and compostable (breaks down in 30 days)
- Flushable in small quantities (check with your water company first)
- 99% dust-free β ideal for cats and owners with respiratory issues
- Lightweight β roughly 50% lighter than clay litter
- Available scented (green tea, lavender, charcoal) and unscented

How to Switch Your Cat to Tofu Litter
Cats are creatures of habit. A sudden litter change can cause litter box avoidance, so always transition gradually:
- Week 1: Mix 25% tofu litter with 75% current litter
- Week 2: Mix 50/50
- Week 3: Mix 75% tofu, 25% old litter
- Week 4: 100% tofu litter
If your cat shows reluctance at any stage (going outside the box, scratching around but not using the tray), slow down the transition. Some cats switch instantly; others need 6+ weeks.
Important Warnings
- Flushing: While tofu litter is technically flushable, many UK water companies (including Thames Water) advise against flushing ANY cat litter due to the risk of Toxoplasma gondii entering waterways. Composting is the eco-friendlier disposal method.
- Kittens: Some kittens may try to eat tofu litter out of curiosity. While non-toxic, ingesting large amounts can cause digestive upset. Monitor kittens closely during the first week.
- Humidity: Tofu litter absorbs moisture from the air. Store in a sealed container in a cool, dry place. Bathrooms can cause unused litter to clump in the bag.
Frequently Asked Questions
Is tofu cat litter safe for kittens?
Yes, tofu litter is non-toxic. However, very young kittens (under 8 weeks) may try to eat it. While small amounts won’t cause harm, monitor closely and remove any litter your kitten appears to be consuming.
Can I flush tofu cat litter?
Technically yes β it dissolves in water. However, UK water companies generally advise against flushing any cat litter due to Toxoplasma gondii concerns. Composting (for non-edible gardens only) is the recommended disposal method.
Does tofu litter smell?
Fresh tofu litter has a very mild, slightly sweet scent. It controls urine odour well through absorption, but solid waste should still be scooped daily. The charcoal-infused variants offer the strongest odour control.
