100% All-Natural Ingredients

Nothing your cat shouldn't touch. We use only the finest natural ingredients, selected for how well they absorb, clump, and keep your cat safe.

Raw pea fiber pellets

Pea Fiber

We use pea, not soybean. Pea fiber absorbs moisture faster and holds up better in the litter box. This gives PurrMax its light weight and fast, dust-free clumping.

Corn starch in a wooden bowl with a scoop, next to a corn cob

Corn Starch

A natural binder that locks clumps together on contact, so they lift out whole instead of crumbling at the bottom of the box.

Every bag is made with pea fiber, corn starch and guar gum, plus a natural deodorizer and trace minerals: no clay, no silica dust, no pigments, no fragrances, and nothing synthetic for your cat to inhale, walk through, or accidentally swallow. If it's not safe enough for our own cats, it doesn't go in the bag.

Tofu Litter vs. Clay Litter: Why the Switch Is Happening

For decades, clay was the only option. Today, millions of cat parents are switching to plant-based litter, not for a trend, but for reasons that show up in their homes every day.

FeatureThe old wayTraditional Clay LitterThe natural switchPurrMax Tofu Litter
Primary CompositionClayMined clay (bentonite)PurrMaxPlant fibers: pea, corn, cassava
Clumping & AbsorptionClayClumps, but can crumblePurrMaxClumps fast, scoops clean
Dust & Air QualityClayHigh dust on pourPurrMaxUp to 99% dust-free
Tracking ControlClayClings to paws, scattersPurrMaxMinimal tracking
Disposal & ConvenienceClayLandfill onlyPurrMaxFlushable & biodegradable
Safety StandardClayBlockage risk if swallowedPurrMaxNon-toxic, no dyes or fragrance

The shift isn't just about convenience. Growing concern over dust exposure, the environmental cost of mining clay, and a generation of cat parents who want materials that break down instead of piling up are all pushing the switch, without giving up clumping power or odor control.

How it works

Simple from the first scoop

1. Fill: Pour 1.5 to 2 inches of PurrMax into a clean litter box.

2. Scoop: Remove clumps and solid waste daily.

3. Top up: Refill to depth as needed and toss used litter in the trash.

How to Transition Your Cat to PurrMax

Cats don't love sudden change. Mix PurrMax into your cat's current litter gradually over four weeks for a smooth switch.

Just add a little more PurrMax on top each week. By week four, it's all PurrMax, with no sudden switch and no fuss. Fill the box 1–2 in. deep.

Our story

FAQ

 Frequently Asked questions 

How long does one bag last?

For one cat, a single bag typically lasts about a month with daily scooping. Multi-cat households will go through it faster.

Is tofu litter safe if my cat eats it?

Yes PurrMax Tofu cat litter is made from Natural Ingredients (pea fiber and corn) starch, with no added dyes or synthetic fragrance. As with any litter, it isn't meant for consumption, but incidental contact is not a concern.

What is PurrMax Cat Litter made of?

Plant-based ingredients: pea fiber, corn starch, guar gum, and a natural deodorizer with trace minerals. No pigments and fragrances.

How do I switch my cat over from their old litter?

Most cats do best with a gradual transition. Mix a small amount of PurrMax into their current litter and increase the ratio over 7–10 days, rather than swapping it all at once, cats can be particular about sudden litter changes.

How much litter should I use?

Pour 1.5 to 2 inches into a clean litter box, scoop clumps and solid waste daily, and top up to depth as needed.

Which formula is right for my cat?

  • Bio-Enzyme Odor Lock breaks down ammonia naturally with active enzymes. 
  • Activated Carbon Odor Shield adds activated carbon for 24/7 odor control.
  • Mixed Tofu + Cassava gives the fastest, hardest clumps for easy scooping.

How do I dispose of used litter?

In most areas, yes small clumps break down in water and can go down the toilet instead of the trash. California residents should not flush cat litter; please dispose of it in the trash instead. 

  • Wherever you live, pregnant women and anyone with a weakened immune system should avoid handling used litter, since cat feces can carry a parasite that causes toxoplasmosis.

Is there anything I should know about safety?

For litter box use only; keep out of reach of children. Pregnant women and people with weakened immune systems should avoid contact with used cat litter. Always wash hands after handling.
