Wood is made up of 3 main components: lignin, cellulose, and hemicellulose. When wood fiber is pelletized, the process heats up the lignin, causing it to temporarily liquify. When it liquifies, it serves as the binding agent for the pellet, also causing the sheen on the outside of the pellet.

We recommend scooping every day. However, you only need to scoop solid waste! Any urine will be absorbed into the pellets, and will cause the pellets to break down into sawdust. Shake the litter box to move the sawdust to the bottom of the litter box, revealing the fresh pellets on top.

You can technically use other types of pellets as cat litter. However, these pellets are designed for cats, and are delivered to your door, making them a great option for you and your feline friend.

Start with a layer of the Catalyst pellets in the litter box. Top with an equal layer of your existing litter. With each box change (~every 2 weeks) increase the amount of pellets and add less of the old litter. This transition should take 3-4 litter box changes (~1.5-2 months to complete).

Another option is the mix-in method. Each time you scoop out the old litter, mix in a handful of Catalyst pellets and continue this until the pellets have completely replaced all of the old litter.

We recommend using a sifting litter box, which has a tray to allow you to remove the broken down sawdust. However, you can still use any regular litter box with pellets.

Unfortunately, this product will not work in an automatic litter box.

We recommend doing a full change out of your litter box once a week. However, another indicator that it’s time to change the litter box is when all the fresh pellets have broken down into sawdust.

Catalyst pellet litter is great for anyone who wants a less expensive, non-clumping litter. This litter will not track and saves time on scooping since you only scoop solids.

No, this is a non-clumping litter, so you will not scoop any liquid waste.

Yes, this litter is very safe for your cat! Similar to our clumping litter, this litter is made up of 100% upcycled wood residuals, making it great for your cat and for the planet. There are no other ingredients in this litter besides wood, so it is great for any sensitive cats.

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.

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 a natural clumping agent.

Catalyst litter is the same cost or less per use as the average clumping clay litter (Catalyst is six cents per use, while clumping clay is seven cents). This is because it’s four times more effective, four times more absorbent and lasts twice as long as clumping clay.

We've put together a chart to help you decide which of our three formulas are right for you and your pets. See more here!

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.

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 atcareteam@catalystpet.comand we should be able to accommodate your request.

Domestic orders are shipped via USPS. The shipping boxes are 100% post-consumer recyclable cardboard products. We also love that the UPS is already driving to our homes so adding Catalyst does not add trucks to the road.

If you need more than that, you are welcome to use two orders for one-time purchases, or multiple subscriptions for subscription orders.

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 three 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. Natural and synthetic phenol in liquid form can be found in some cleaning fluids, but not in Catalyst. 

Catalyst does not use any bark or needles; Catalyst does not add any liquid phenol into our product.

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.

All Catalyst products can be used in multi-cat households. Our specific Multi-Cat formula has high clumping strength for more Cat traffic.

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.

At this time Catalyst only ships to households in the USA.

By California law, companies that sell any number of common household products—including anything made from wood and/or wood dust—to residents who live in the state of California must include the Prop 65 warning label on packaging. This label is showing up more frequently because e-commerce business continues to grow and increased inventory is traveling across state lines. For Catalyst Pet, we need to make sure that any litter sold has the label, should it be heading to a California kitty.
