Scoop of Tofu cat litter.

When you purchase through links on our site, we may earn a commission. Here’s how it works.

As every cat parent will tell you, the worst part of living with a feline companion is having to scoop the litter box. It’s gross, smelly, and downright toxic (cat urine is full of ammonia, a gas that can bring on headaches, trigger asthma attacks, and lead to other respiratory issues). But because we love our sweet angel babies, we roll up our sleeves, try not to breathe, and get to shoveling.

Cat litter has come a long way from its clay-based beginning, partly because consumers will jump at any opportunity to make their least favorite task a more pleasant experience for everyone involved. Stop by your nearest pet store, and you’ll likely find litter made from silica, pine, paper, walnut shells, corn cob, wheat, and even grass seed. With innovations for odor and moisture control constantly in the works, it’s anyone’s guess what manufacturers will come up with next. 

Turns out we already have the answer. The newest type of litter is derived from an unlikely source: soy. Yes, you read that right. Your feline can now do their business on dust-free, clumping, and flushable tofu cat litter.

What Is Tofu Cat Litter?

Tofu and corn cat litter.

Tofu litter is made primarily from soybean dregs. Dregs are the pulpy, fibrous part of soy that remains after pureed soybeans are filtered for products like soy milk and tofu. This by-product is typically thrown out in manufacturing. (However, soybean pulp can also be eaten—check out WoonHeng’s recipe for okara patties). In the case of tofu cat litter, the soy pulp is dried and combined with plant-based starches to form a cylinder-shaped litter pellet. Pea fiber is a top choice due to its high absorption.

Depending on the manufacturer, the soy-based cat litter may have other ingredients to control odor or added binders, colors, and fragrances. Tofu cat litter is a non-toxic, natural alternative to conventional cat litter. It’s softer in texture, lightweight, and highly absorbent.

Why Is Tofu Cat Litter Good?

While tofu-based cat litter may sound like a novelty item, there’s more than one reason you might consider switching to soy cat litter.

5 Benefits Of Tofu Cat Litter

  1. Health and safety: Tofu cat litter is free from harmful toxins. Unlike conventional cat litter, which can cause respiratory issues in cats and humans over time, soy-based litter is 100 percent safe and can even be ingested (please don’t eat the cat litter). In contrast, if your cat eats traditional clay litter, you’ll need to make an emergency vet visit. Learn more about the dangers of clay litter via The Pet Health & Nutrition Center.
  2. Eco-friendly: Unlike clay and crystal cat litter, tofu litter is biodegradable and compostable.
  3. Low dust and tracking: Say goodbye to the trail of litter coming from the litter box and traveling all over the house. Tofu pellets are larger and less likely to stick to your cat’s paws and fur. Soy-based pellets are also virtually dust-free (assuming you get a formula without extra binding ingredients).
  4. High absorbency: the absorbency of tofu makes it good at clumping and odor control.
  5. Easy cleaning: Unlike traditional litter, tofu litter doesn’t cement itself to the litter box, so scooping is much easier. Tofu litter is also flushable since it dissolves in water.

Top 3 Tofu Cat Litters

What makes a quality cat litter? I considered the following factors when choosing the best tofu cat litter:

  • Cleanup: A clumping litter makes for easier cleanup.
  • Dust: Dusty litter is especially bad for those with people and cats with respiratory issues like allergies.
  • Ease of use: A litter that can be easily lifted and poured is essential for those with mobility issues.
  • Odor control: A quality litter will neutralize the smell of urine.
  • Price: Along with food, litter is one of the most costly purchases for your cat.
  • Scent: Cats rely heavily on their sense of smell; a strong scent may be too overwhelming for your furry friend.
  • Tracking: Because feeling litter under your feet is the absolute worst.

My Personal Experience With Tuft + Paw Soy Litter

I tested out Tuft + Paw’s Really Great Cat Litter and just love it. In fact, I’ve found my new favorite litter. Tuft + Paw’s Really Great Cat litter is just that—it’s super duper awesome. The biggest issues I’ve had with litter previously are tracking and dust. With Tuft + Paw, there’s virtually no tracking. I haven’t noticed any dust, which is a huge win (I have asthma). The litter does a great job of reducing odor, too. Honestly, there’s genuinely nothing about its performance that I don’t like. My cats took to it immediately, and we’ve been using it ever since!

Pidan Signature Tofu Blend Review

  • Ingredients: organic bean dregs, starch, guar gum, bentonite (with STV particles)
  • $18.99/7.9 lb. bag = $2.40/lb.
  • Low dust and tracking
  • Great clumping
  • Also available in a formula without bentonite
  • Scented using deodorant granules
  • Also available with blood test particles to monitor cat’s health

Pidan’s Tofu Cat Litter Mix is 70 percent tofu cat litter and 30 percent bentonite clay. The small-particle bentonite fills up the gaps of the tofu litter, giving this formula superior clumping capability. The non-toxic STV particles offer additional odor control. Most users love the smell of this formula (often described as vanilla).

Pidan offers several different tofu litter formulas, including tofu litter with a blood test that detects hemoglobin at a concentration as low as 0.1 percent. You can also purchase Pidan without bentonite or with added activated carbon for odor control.

Nourse Chowsing Activated Carbon Review

Nourse Chowsing Activated Carbon
  • Ingredients: soybean dregs, corn, starch, guar gum, activated carbon
  • $18.99/6 lb. bag = $3.17/lb.
  • Low dust and tracking
  • High flushability
  • Charcoal for odor control
  • Unscented
  • Also available in Original (milk scent) and Great Tea

As one of the original tofu cat litters, Nourse Chowsing has a larger following than the other two litters on this list. Users praise this litter for its low dust and low tracking. For those seeking a flushable option, Nourse Chowsing is your best bet. It’s highly dissolvable, but some users complain about the somewhat sticky consistency of the litter clumps.

Nourse Chowsing is available in three varieties: original (milk-scented), green tea, and activated carbon. For added odor control, I’d choose the third option.

How To Transition Your Cat To Soy Litter

Whenever transitioning to a new cat litter, it’s essential to go slow. Research suggests transitioning over a six-day period is ideal to minimize stress. Gradually incorporate the new litter by mixing it in with the old. To start, switch out 25 percent of the current litter with your new litter and progressively reduce this amount until you’ve fully transitioned.

A sudden and complete switch may stress your cat out and lead to destructive behavior like spraying urine or excessive scratching. Take care not to stress your kitty out during the transition. Stress and fear can lead to anxiety-induced inflammation, urinary difficulty, and long-term issues.

Frequently Asked Questions

I had plenty of questions about tofu cat litter, and I know many other owners do, too. I cover a few of the top ones here, but if I didn’t get to yours, let me know in the comments.

Does Tofu Cat Litter Clump Pee?

Yes, tofu litter does clump pee and does so remarkably well. It absorbs liquids quickly, creating an easy-to-scoop clump. Unlike pine or clay, there is so much mess or goopy residue left behind.

How Often Do You Change Tofu Cat Litter?

Scoop your litter box daily, and change the litter every two to three weeks. We cover everything you need to know about how often to change cat litter, including step-by-step instructions for changing your cat’s litter box.

Can You Use Tofu Cat Litter With An Automatic Litter Box?

If you shelled out the big bucks for an automatic box like the Litter-Robot, you might be able to use tofu cat litter with your auto litter box. Brands vary, so you must confirm which litter is compatible with your litter box.

Can Tofu Litter Be Flushed?

Technically, yes, most soy cat liters are flushable. They dissolve in water. Flushing cat poop down the toilet, however, is unsafe and also illegal in many municipalities. Cat feces contain harmful bacteria that can contaminate the water supply, in particular, toxoplasma, which water treatment facilities do not treat.

Can Cats Eat Tofu Litter?

Tofu cat litter is safe to ingest, but you should not let your cat eat it. It is not harmful in small quantities, but making it a regular snack is not safe. If your cat regularly eats litter or likes the flavor of a certain brand, soy may not be a good pick.

Do You Have The Right Litter Box?

Litter is only half of the equation when it comes to setting up a comfortable potty sport for your fur baby. The litter box itself matters. You can try disposable boxes, stainless steel boxes, plastic boxes, or make your own. Some cats like covered boxes for privacy, while others prefer an open-air setup. Extra large kitties like Maine Coons need extra large litter boxes, and you should always have at least one more litter box than you do cats. Keeping these simple tips in mind can help make your kitty’s potty experience comfortable and healthy.
