Why Trust Cats.com

I’ve tried my share of non-clay litters over the years, and I’ve seen it all—the good, the bad, and the clumpy. I was curious to see how Catalyst stacked up against similar products.

Over several weeks of testing, I focused on some key points: smell, texture, dustiness, and clumping ability.

Throughout the testing process, I considered a range of cat parent needs and weighed them against the pros and cons of this litter. I also went through dozens of reviews from other cat parents to understand how they found this natural litter.

Catalyst Cat Litter and Brand Overview

Catalyst is committed to sustainability and environmental responsibility, from product development to packaging. They’re accredited by the Pet Sustainability Coalition, a non-profit organization dedicated to creating a more sustainable pet industry. Catalyst litter also comes in LDPE #4 plastic bags that are 100% recyclable.

Introduced in 2020, Catalyst’s flagship product is its pine softwood cat litter. This upcycled material is sourced from the parent company, Lignetics, Inc., which converts waste from regional sawmills into litter.

The brand also carries small animal bedding, biodegradable pet waste bags, a sisal litter mat, and a sturdy steel litter scoop. They recently released a non-clumping pine pellet litter, which may appeal to those seeking a low-tracking litter.

What Kinds of Litter Does Catalyst Offer?

Catalyst offers three natural softwood formulas:

Multi-Cat Litter
Healthy Cat Litter
Unscented Cat Litter

The primary ingredient in all three varieties is clean, upcycled pine softwood.

This upcycled pine wood is not only highly absorbent, creating well-formed clumps and locking in odors, but it’s also biodegradable and compostable.

One of Catalyst’s standout features is its remarkable efficiency, as one pound of Catalyst is designed to do the work of four pounds of clumping clay litter. This means you’ll need to change Catalyst less often, so it’s a long-lasting and cost-effective solution. Additionally, this contributes to a smaller environmental footprint by reducing production and transportation pollution.

Catalyst litter is made in America and is available in 10 and 20-pound bags. Depending on the number of cats in a household, a 10-pound bag of Catalyst litter could last up to a month.

#1 Catalyst Multi-Cat Formula

$12.35 per month At CatalystPet $14.99 At Chewy

The Catalyst Multi-Cat litter is designed to meet the needs of multi-cat households with its enhanced clumping strength and added wood scent. This litter is created with softwood, zeolite (a porous, highly absorbent material), natural clumping agents, natural oil, and pine scent.

Liz Coleman / Cats.com

While some cat parents found the natural scent too strong, others found it pleasant and earthy. Personally I enjoyed the woodsy smell.

The litter’s lightweight nature makes it easy to lift and pour but can lead to some tracking due to the tiny sawdust grains.

The Multi-Cat formula formed clumps that held together well and were easy to remove from the litter box. However, some users noted the clumps fall apart if scooped too aggressively. I found one workaround for this was giving the clumps time to solidify. If you wait, clumps will be easier to scoop without crumbly pieces breaking off.

While there was a little dust when pouring the litter, there was nearly no dust when scooping. Plus, dust from this litter is safer and less harmful to your cat’s lungs than silica clay dust.

What We Liked:

Long-lasting and cost-effective
More eco-friendly than clay
Highly absorbent
Lightweight and pillowy soft
Lab testing shows Catalyst litter is 10x more effective at odor control than clay litter

What We Disliked:

Some cats and people may find the natural scent to be overpowering
May track more than clay

#2 Catalyst Unscented Formula

$12.35 per month At CatalystPet $13.99 At Chewy

Catalyst Unscented Litter is the ideal choice for cats and people with sensitive noses.

Unlike the other Catalyst formulas, the brand’s Unscented Litter maintains its subtle smell without the addition of pine scent or zeolite among its ingredients.

Despite being unscented, the litter still carries a faint pine smell. However, it’s subtle, unobtrusive, and is really only detectable at close range.

What We Liked:

Has no added scent
The natural pine smell is understated and subtle
Clumps well

What We Disliked:

Not completely smell-free

#3 Catalyst Healthy Cat Litter

$12.35 per month At CatalystPet $14.99 At Chewy

Catalyst Healthy Cat litter is a great choice for cat owners who prioritize a clean and healthy environment for their pets and themselves. This formula is designed to keep surfaces clean by minimizing dust, making it easier for you and your kitty to breathe.

Liz Coleman / Cats.com

While no litter can be completely dust-free, this one does a pretty good job—especially considering it’s so lightweight. And the generated dust will be far less harmful than breathing in clay dust.

What We Liked:

Keeps dust to a minimum
Mild added wood scent

What We Disliked:

Some cats (and people) might find the scent overpowering

What Do Customers Think of Catalyst Cat Litter?

While there are some concerns about tracking and dust, overall, customers express mostly positive experiences with Catalyst litter. Here are some highlights.

Positive Reviews

Positive reviews praise the litter’s absorbency and odor control. Most people appreciate the well-formed clumps and how easy it is to scoop. Many people liked the natural woodsy smell, the soft texture, and this litter’s environmental friendliness. They also like that it’s long-lasting and can go longer than clay between changes.

“This litter made from wood chips at first had me apprehensive….and one of my kitties thought so too…..but after a transition period all six kitties use the litter with no problem – and it clumps very well….they advertise it doesn’t track but it does…the litter keeps the smell in check too – I will not go back to clay litter…..and Catalyst is light weight….easy to handle – I would highly recommend this litter – oh – it lasts longer too!!! TRY IT!!” – Gracia reviewing, Catalyst Pet Multi-Cat Formula Cat Litter on Apr 2, 2025

“I dislike the smell of traditional litter. The unscented Catalyst has a nice outdoor-woody smell without being overpowering. It does a good job disguising odors and clumps easily. I feel it needs a scoop with bigger holes to be more efficient, but otherwise is as easy to care for as sand/clay litters. No dust, cats took to it immediately.” – by Kimi reviewing Catalyst Pet Unscented Formula Cat Litter on Mar 30, 2025

Negative Reviews

Some negative reviews mention tracking and dust. But remember, this is the case with most lightweight litters. Some folks were displeased with Catalyst’s clumping ability, and others didn’t like the natural pine smell.

“I am not sure if it is the feel of the litter under their paws or the odor (Even unscented has a pine fragrance), but they will not use it! – by Alycat reviewing, Catalyst Pet Unscented Formula Cat Litter on Feb 17, 2025

“I got this since it had good reviews and I wanted to try something new (my friend also uses wood chips and said they work better than cat litter and so I thought this would be good since it’s modified for cats). My cats wanted nothing to do with it, it was SO dusty and just made my bathroom smell like a petting zoo. I’m gonna try pretty litter next. -by Josie, reviewing Catalyst Multi-Cat Formula on Feb 20, 2025

How Much Does Catalyst Cat Litter Cost?

At first glance, the cost of Catalyst may seem a little high. However, considering its effectiveness and longevity, this litter could lead to significant cost savings.

On Chewy, each formula has the same price:

10-pound bag: $1.50/pound
20-pound bag: $1.20/pound

But don’t be fooled by price per pound.

While Catalyst might cost more per pound than clay litter, you can use less of it—which means greater savings long-term.

According to a survey of over 1,000 cat parents, Catalyst litter is projected to save an average of 43% per month compared to clay litter, 50% compared to other natural litters, and 54% compared to crystal litter (on the company’s 40-lb+ per month eco-hero plan).

Your savings may be even greater if you subscribe directly from the company’s site.

Where Is Catalyst Cat Litter Sold?

You can purchase Catalyst litter on Chewy or directly from the company’s site. All orders from the Catalyst website have free shipping. The brand’s subscription option lets pet parents save money while ensuring they never run out of litter.

Overall, Is Catalyst Cat Litter a Good Choice?

Yes—if you’re looking for an affordable and effective alternative to clay litter, Catalyst is definitely one to consider. This natural litter is sustainable, practical, and cost-effective. It’s a good choice for conscientious pet parents on a budget.

However, as with all litter, Catalyst has some tradeoffs to consider. You’ll have to decide for yourself if a bit of tracking is a deal-breaker. As I see it, the scatter problem could be (mostly) solved with a good litter mat, a high-sided litter box, and regular cleaning.
