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.

We’ve lowered the price on ALL Catalyst subscriptions. One of the ways we’ve made that possible is by combining multiple shipments into one shipment on subscriptions with smaller monthly amounts.

For example, if you regularly had been receiving one 10lb bag per month for $20, you will now receive 20lbs every two months for $28.50 total. 20lbs of the highest performing natural cat litter on the planet will pounce onto your doorstep with that fresh saving-the-planet swagger while saving you $11.50 with each delivery.

More bags delivered at once cuts down on packing materials and transportation emissions. This improved model saves you money AND reduces environmental impact!

• We know our customers are concerned about care of the environment, and so are we. We carefully considered different materials for our bags and settled on the #4 LDPE bag. We want our customers to have the best possible experience using our products, and this type of bag is durable and protects from weather damages during delivery.
• We also chose this bag because LDPE #4 plastic bags are 100% recyclable. There are numerous recycling facilities nationwide that take our bags. You can recycle our bags anywhere that takes grocery bags for recycling. Location can be looked up online here: https://www.plasticfilmrecycling.org/recycling-bags-and-wraps/find-drop-off-location/
• We are constantly working on innovations to reduce our environmental impact this even further. Currently, we are working with a plastic neutral NGO and formulating a way to add a bio-based polymer into our production line so stay tuned for more on that very soon!
• Every Catalyst Pet purchase online is now certified Plastic Neutral. By partnering with rePurpose Global, Catalyst Pet is donating a percentage of every product purchase to collect and reuse one ocean-bound plastic pouch for every one it sells online. By funding cutting-edge recycling technologies and supporting ethical wages for marginalized waste workers in India, the company is enabling rePurpose Global to tackle harmful plastic waste streams otherwise destined for landfills and waterways worldwide. By taking this bold commitment, every Catalyst Pet purchase online will now carry a net zero plastic footprint.

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.

Due to Catalyst's lightweight litter, Litter Robot and sifting litter boxes can occasionally encounter issues sifting the litter. Our users have found that using somewhere between a 50%/50% mix of Catalyst and Clay and a 80%/20% mix (more Catalyst) can solve this problem.

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.

Subscribe to Catalyst and receive 13% off your bag each month. Your subscription will ship approximately every 30 days. If you need to pause, cancel, or swap your subscription product to a different formula, you can do so at any time.

Our litter is available in 10-pound bags online. Typically, one bag per cat per month is sufficient!

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.

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.

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. 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.

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.

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 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.
