Catalyst Pet is a new, completely sustainable, high-performance cat litter. Catalyst shines in all the ways a great cat litter should so pet parents can give their cats the best while also taking care of the planet. Engineered from upcycled soft wood that gives a soft texture that cats prefer, Catalyst provides superior odor control, unrivaled cat acceptance and strong clumping ability for easy scooping. It is 99 percent dust-free and has very low tracking. Catalyst is also lightweight. One pound of Catalyst does the work of three pounds of clumping clay. Catalyst is available in a variety of formulas, including Healthy Cat, Multi Cat and Unscented.
