"All four of our cats, ranging in age from 1 to 15, gave Catalyst paws-up approval. We introduced Catalyst properly, slowly mixing it in with existing litter brand. I like that Catalyst is a clean, environmentally friendly litter that did not kick up dust and came in lightweight bags. Just like us, our cats deserve clean bathrooms. Catalyst is a good litter option." (Arden is not a paid spokesperson nor received monetary compensation for this testimonial.)
"I’ve tried every type of clay litter under the sun and have found NOTHING to help with the odor of having four cats. Catalyst is a dream come true. The pine smell is amazing and the odor control is unmatched. Not to mention it is super light weight and clumps better than any clay litter I ever used. It also doesn’t track like regular clay litter. 10/10 would recommend. I’m not going back!"
"Phenomenal quality! Great long lasting smell! Traps and drys urine and shields fresh poop from any sorta smell. So easy to scoop after duty and salute you guys."
"I love the way Catalyst litter works and keeps my house not smelling like a litter box. I have 4 cats and this litter really works. It’s better for the environment and it’s much more pleasant to deal with."
"No smell what so ever...no dust..no mess!!! Clumps like a dream and so east to scoop! Thank you again for everything and im shopping with you guys from now on!! Fast delivery!!! And my water bottle loves the new sticker!!!"
"I’ve had cats for over 20 years. I’ve always used clay litter but have recently become allergic to dust. So I began to try different alternatives the pet store has to offer such as corn, wheat and wood. All have let me down in different ways from smell to lack of clumping. But this cat litter is top notch. Clumps beautifully. You use a lot less then clay and it lasts 2-3 weeks compared to adding the clay litter twice a week. My cats love it and used it immediately."
"This is the best cat litter ever conceived. All natural, no messy dust or tracks from paws and the packaging is very cool!"
"Like this much better than our clay based litter. Smells kind of like woodchips. Cats are happy."
"Awesome product, can't believe it took so long for someone to come up with such a planet friendly solution. My cat loves it, its clean, no odor, easy to clean up. I love it."
What Cat Parents Are Saying
Recommended By The Experts Who Know Best
We don't just have happy cats — we have the trust of veterinarians and certified pet health coaches who've seen the difference Catalyst makes.
As a cat parent with an old and arthritic cat, I made the switch to Catalyst Pet a while ago. As a veterinarian, I recommend owners of older cats use a softer litter — Toby has really enjoyed the softness of Catalyst on his old toe beans. As a human, I also enjoy its great odor control, and love that when our cats leave the box they don't track hard bits of litter all over.
