The tofu litter clumps tightly, the vanilla scent is gentle, and scooping is actually easy now. The box stays so much fresher.

I switched for the low dust and stayed for how little it tracks. Both cats took to it immediately, and I’m not vacuuming the hallway every afternoon.

Flushable, plant-based, and it actually controls odor. We have three cats and this is the first litter that kept up without taking over the apartment.

Subscription delivery means we never run out. It’s softer on their paws, and we’re not dumping clay into the trash every week.

Frequently Asked Questions
Is tofu litter safe for cats?
Litter Science is made from plant-based fibers and designed to produce very little dust, helping reduce exposure to traditional clay litter dust.
Cats may accidentally ingest small amounts of litter while grooming, so choosing the right litter matters. Repeated ingestion of clay or crystal litter may lead to gastrointestinal obstruction. Litter Science is made primarily from plant-derived materials and has not been shown to cause serious toxicity when small amounts are accidentally swallowed.
However, it is not intended for consumption, and no litter is entirely risk-free if ingested. If your cat frequently eats litter or shows signs of digestive issues or discomfort after switching, discontinue use and contact us at support@litterscience.com.
Is Litter Science safe for septic systems?
Litter Science is water-soluble, and its clumps gradually break down in water. However, water solubility does not guarantee that a product is safe for every plumbing system or septic setup.
If you’re considering flushing small amounts, check your local regulations and your septic system manufacturer’s guidance first. Avoid flushing large quantities, and never flush litter if your plumbing or septic system is not designed to handle it. When in doubt, dispose of used litter in the trash.
Can I order more than three boxes?
The product page currently offers one-, two-, and three-box options. You can increase the quantity to more than three in your shopping cart. For larger households or bulk orders, contact us at support@litterscience.com, and we’ll help you arrange it.
When will my first order arrive?
Most orders arrive within 3 business days. Once your order ships, we’ll email you tracking information so you can follow its progress.
If your delivery appears delayed or your tracking information hasn’t updated, email support@litterscience.com with your order number, and our team will help you look into it.
