5 Reasons to Swap Clay
for Wood-Based Cat Litter
Thousands of cat owners everywhere are making the switch from clay to wood for
a more sustainable, healthier, cheaper, and better odor-controlling litter.
Better for the environment
Every year, 5 billion pounds of clay are stripmined in the US for cat litter, causing ecological harm. Not only that, clay litter does not decompose, filling up landfills for thousands of years!
Catalyst Litter is eco-friendly, made from upcycled wood waste that would have otherwise been thrown away. It's a sustainable choice that benefits both cats and the environment. Read more
Clumps solid for easy scooping
With wood-based litter, you don't have to sacrifice the benefits of clumping. In fact, thanks to our patent-protected formula, our wood litter clumps are even more robust and cohesive than traditional clay options. Experience the next level of clumping efficiency, powered by nature and perfected by science. Read more
Healthier for your cat - and for you too!
Bentonite-based clay litters can release harmful silica dust, harming cats and humans. Inhaled silica can lead to respiratory issues, while ingesting litter can cause cat stomach problems. Catalyst litter is free from silica dust and safe for ingestion, supporting better health. Read more
Never worry about smell again
Catalyst’s odor control means you’ll never have to worry about a smelly litterbox again. Amazing odor control is one of the things that existing Catalyst customers consistently rave about. That's because wood is much better at absorbing your cat’s *ahem* “stuff” than clay! Choose from 3 formulas that best fit your needs. Healthy Cat has a soft pine scent, Multi-Cat is great for households with more than one cat, and Unscented is purr-fect for a smell-free litter! Read more
Litter that lasts longer
We get it - at first, we seem a bit pricier than other brands. But don't be fooled! On average, we are at least 43% cheaper than other litters, making us the most affordable on the market! That's because we're so absorbent, so 1 pound of Catalyst does the work of 4 pounds of Clay. To get the real picture, you have to divide our price by four to get to the actual monthly cost.

None of the litters I've tried that promise odor control are as pleasant as Catalyst, and we live in a small apartment, so smells travel fast. I love how lightweight it is and how affordable. I love the room smelling like it's in a forest!

Catalyst For The Win!!!
Hands down the BEST cat litter I have ever used. I have two cats so I got the multi cat subscription. You’d never know I have a litter box in my home. The slight woody smell is pleasant and it clumps beautifully. I’ll never go back to clay litter. Catalyst is simply the best!
Denise O.
BEST kitty litter we’ve tried so far! Beats out Pretty Litter and 6 different clay litters we’ve tried. We have two large Maine Coons who poo and pee ALOT. This litter masks the odors 💯 percent🙌

I love this cat litter
I love this cat litter, I am so glad I ordered it it is the best I have seen and it definitely smells amazing even when my cat goes potty it is so much easier to keep clean, and easier to scoop up, I give it a 5 star rating, I don’t think I will ever go back to the clay litter, I believe this litter will last longer and don’t think I need another bag for at least two months

There’s nothing better. Especially when you have a lot of cats
We have 6 cats and have tried many different litter brands. We either dealt with litter that couldn’t withstand all 6 cats or was way too expensive to buy monthly for all 6 of them. When we came across catalyst we were skeptical at first but eventually we figured “why not”. And we’ll never turn back. It’s light weight but all powerful. Their scoop makes it so much easier to keep the boxes completely clean. The price is so reasonable especially with having 6 cats. It absorbs their pee like no other and there is no smell. They don’t seem to track litter on their paws nearly as much. We love this litter.

You won’t be disappointed!
Waited a month to review: I was skeptical, but wanted to give it a fair try. I have two cats sharing one litter box, so time would definitely tell if this litter was going to live up to the hype. We have tried all of the clumping, scented , pellets, crystals. This was something new for sure, and didn’t look (or smell..or “not” smell) like it would be effective. I was very wrong, and happy that I was. Never had any nasty litter box smell. No urine smell, no feces smell, no dust when cleaning. Easy to scoop. Minimal tracking. There’s literally NO smell at all. Nothing. Not the smell of the litter and not the smell of a litter box. Well, other than a clean smell, and I’m all for that! One bag for two cats for a month… that’s worth the price for us. Customer for life here.

I was skeptical, I used
I was skeptical, I used other wood litter, and nothing worked, so I tried yours. I have four cats and I was like no way would this work. You proved me wrong. I am paying less money versus store clumping litter. The smell is non-existent. You would never know I had cats. My sister even noticed. Love this litter and my cats took to it right away and they love it, no more smelly pans!

FINALLY!! Catalyst is amazing!!
FINALLY…a cat litter that is good for my kitties AND the environment!! Catalyst is SO much better than ANY litter I’ve ever tried - and I’ve tried them all! The scent smells like cut wood, which I love! SO super easy to scoop and to change. It’s much more lightweight than clay litters, so easy to dispose of. I’m so happy to have finally found the perfect litter! And my cats took right to it, no need to stage the introduction. I simply threw out the clay litter and replaced it with Catalyst!

Best Litter on the Market!!
We've tried them all, old-school litter, scoopable, Pretty Litter, and a few others. Then we stumbled upon Catalyst and thought we'd try it out. So glad we did, wouldnt use anything else ever again! This stuff absorbs, scoops easily (with a larger type of scoop), doesn't stink at all. We highly recommend!!

Best cat litter I have ever used!
Best cat litter I have ever used. I do not gag anymore when cleaning the litter boxes. I have 3 cats and they like it. I prefer the unscented. Easy to clean and very minimal tracking. I put a bath rug on the outside for them to step on and it catches the all the product from their paws! Love this product!
Trina T.
Exactly as advertised
I like it - and my cats seem to like it - more than the clay litters. I like the lighter weight for sure, being an old lady, and it's much nicer sifting, and doesn't make pee concrete. It doesn't get scattered all over the house. There is much less odor than with clay litter, too. It costs out approximately what the old litter cost, and home delivery is great! Also, I'm glad not to be generating all those big plastic jugs as well. So far, it's exactly as advertised

The Catalyst Experience

We think Catalyst does a great job by itself, but using wood litter has some differences to using clay litter. It's like using a smartphone - they're great at what they do, but your experience can be enhanced by a protective case and a screen protector. By using a wide-slatted scoop and a great litter mat, you can get the most out of the Catalyst Experience. We think that the scoop and the mat below are the best, since they've been extensively tested in our Cat Lab against all different types of scoops and mats, and have come out on top.

Specialized Scoop

You really benefit from using a wide-slatted, specialized scoop to deal with our clumps. Think of how often you use a scoop - and think of how much better your life will be with a much more pleasant scooping experience!

Natural Litter Mat

Catalyst is super lightweight, which means that litter can occasionally get stuck to your cats paws and leave the litterbox. Luckily, our natural litter mat cuts out 90% of tracking (based on our testing), because the natural sisal fibers work remarkably well at "hooking" wood fibers. Nature's solutions are often the best!

If you're interested, we strongly recommend buying our starterpack at checkout.


Because we believe that you should enjoy the Catalyst Experience to the fullest.

What is Catalyst
made out of?
Our primary ingredient in all three varieties is clean, upcycled pine softwood. This material is sourced from regional sawmills converting what would have been waste into upcycled litter. No contamination is allowed in the wood: no paint, no stain, or any previously used wood.
How to switch to
wood-based litter?

One bag per cat per month is the general rule of thumb. Our litter was scientifically engineered so that one pound of Catalyst does the work of four pounds of clumping clay litter. We love that efficiency reducing both production and transportation pollution.
On average, the vast majority of people receive their litter within 3-4 business days, and usually sooner. Every order is processed to ship out within one business day after it is placed. It is shipped with the USPS three-business-day service and includes tracking and insurance. For your peace of mind, orders are tracked through the email or mobile number you provide to us.
Due to Catalyst's lightweight litter, Litter Robot and sifting litter boxes can encounter issues sifting the litter.
Our primary ingredient in all three varieties is clean, upcycled pine softwood. This material is sourced from our parent company Lignetics, regional sawmills converting what would have been waste into upcycled litter. No contamination is allowed in the wood: no paint, no stain, or any previously used wood. The wood is captured straight off of a mill making Catalyst litter super clean and the litter and sawmill very efficient. Healthy Cat and Multi-Cat, in addition to the pine wood, include a biobased oil, a natural clumping agent, zeolite and a mild natural scent. Unscented, in addition to the pine wood, includes only a biobased oil and a natural clumping agent.
Actually based on our surveys of over 1,000 cat parents, Catalyst litter will actually SAVE you money compared to the average clumping clay litter! We get it, the price seems high at first - but you have to divide our price by four to get to a comparable price to clay, and that's because Catalyst is four times more effective, four times more absorbent and lasts twice as long as clumping clay. On average, you'll save 43% per month vs. clay, 50% vs. other natural litters, and 54% per month vs. crystal litter (assuming you're on our 40lb+ per month eco-hero plan). 
To keep it simple, we recommend healthy cat for cat parents with one cat, and multi-cat for cat parents with multiple cats, unless you or your kitty have a sensitive nose (or just don't love the lightly scented pine smell of our litter), in which case we recommend the unscented!
Yes. Catalyst Litter is biodegradable and can be composted. However, we don’t recommend using it as a compost in your garden or in any soil that will be used to grow food. All cat waste has a risk of carrying toxoplasmosis. When disposing of the litter, please follow all local regulations in your region. Our litter is technically flushable, many regulations and BMPs advise not to flush any litter. Please follow your local regulations and BMPs.
If I select 40lb (or other sizes) for my order, what sizes of bags will I receive?
All orders will come in some combination of 10lb and 20lb bags (i.e. a 30lb order is a 10lb bag + 20lb bag, a 40lb order is 2 20lb bags). If you prefer to have everything come in 10lb bags instead of any 20lb bags, please email us at and we should be able to accommodate your request.
How is my Catalyst litter delivered?
Domestic orders are shipped via USPS. The shipping boxes are 100% post-consumer recyclable cardboard products. We also love that the USPS is already driving to our homes so adding Catalyst does not add trucks to the road.
Why should I subscribe to Catalyst litter?
Subscribe to Catalyst and receive at least 18% off your bag each month. If you need to pause, cancel, or swap your subscription product to a different formula, you can do so at any time. If you need to pause, cancel, skip an order or swap your subscription product to a different formula, you can do so at any time from either the portal or via SMS. We want to make it so incredibly easy to manage your subscription, you won't have to ever worry about running out or having too much ever again!
What sizes are available?
Our litter is available in order sizes from 10lbs to 80lbs per order. If you need more than that, you are welcome to use two orders for one-time purchases, or multiple subscriptions for subscription orders. All orders will come in some combination of 10lb and 20lb bags (i.e. a 30lb order is a 10lb bag + 20lb bag, a 40lb order is 2 20lb bags).
Most cat lovers are not aware that traditional clay litters are usually made of sodium bentonite, a mineral that is strip-mined and not biodegradable. A 2017 report reveals that more than five billion pounds of sodium bentonite is mined each year just for cat litter with the vast majority ending up in landfills—more than 125,000 truckloads each year. Catalyst solves this problem because it is biodegradable and does not require precious resources for its manufacture. In fact, the upcycled soft wood fiber used to make the litter is collected from wood processing facilities that would otherwise send it to a landfill. Because one pound of Catalyst does the work of four pounds of clumping clay litter, it also reduces pollution and carbon emissions that result from production and transportation. The wood fiber starts out as a by-product from a sawmill on the industrial plant level. We then take these materials and upcycle them to create the litter. Because it is a by- product, we are not sacrificing additional materials from our beautiful planet. Our motto around here is right on every package: Love your pet, Change your planet.
Yes! Your cat’s health is of primary importance to us, and we only offer products that we know will keep your cat healthy and well. Some customers have asked us about the safety of pine as a litter because pine contains phenol, which is typically found in the bark and needles of pine trees. Rest assured, Catalyst does not contain any phenols as we don't use any bark or needles in our product.
What size of litter box is Catalyst designed for?
One 10lb. bag of Catalyst is 1/3 of a cubic foot. If using a large box (15x18 inch) 1 bag will fill the pan to 2.5-inch depth leaving 4lb. of litter remaining in the bag after filling. The remaining litter should allow the user to scoop and replace the litter over the next 30 days.
Can Catalyst be used for multi-cat households?
All Catalyst products can be used in multi-cat households. Our specific Multi-Cat formula has high clumping strength for more Cat traffic.
Is Catalyst litter low tracking? Does it stay in the box?
Catalyst is dust free; the challenges associated with airborne dust will no longer be an issue. For highly active and jumping and digging cats using a higher sided box and a tracking pad can help to reduce tracking. Catalyst should track either about the same or less than comparable litters.
Do you have international shipping?
At this time Catalyst only ships to households in the USA.
