Catalyst Pet’s Multi-Cat Formula makes litter box maintenance simple, safe, and sustainable—especially for homes with more than one feline friend. Made from upcycled softwood, this litter delivers powerful performance with a smaller environmental pawprint. Designed for multi-cat households, it offers enhanced natural odor control, superior clumping, and zero airborne dust to keep your home fresh and clean. A light natural forest scent is gently released when the litter is used to help keep your home smelling fur-esh.

Unlike clay litter, Catalyst is lightweight and naturally resistant to mold, making it a safer choice for you and your cats.

We’re also proud members of the Pet Sustainability Coalition, committed to a cleaner future for pets and the planet. Help us overthrow the clay litter aisle by choosing a high-performing, sustainable alternative!

100% Upcycled Softwood, Natural Clumping Agent

Add approximately 2-3 inches of Catalyst cat litter to a clean, dry litter box. Scoop out waste daily with a litter scoop and dispose of properly. Do a full clean out of the litter box and replace all the litter in the litter box with fresh litter at least once a month.
