Why this pick won
Catalyst is made from upcycled soft wood fiber (a sawmill byproduct) and clumps hard enough that clay converts don't notice the switch. One 10 lb bag does the work of roughly 20 lb of clay, offsetting the sticker price. Unscented, low-dust, and compostable where local rules allow.
