Catalyst Soft Wood is the strongest all-around pick in this comparison for cats that reject pellets.
A soft, sand-like pine litter that avoids the pellet feel many cats reject while keeping dust and smell manageable.
A designer tofu litter with nearly zero dust and very low tracking, but it is expensive and mostly for people who value aesthetics and convenience.
Two soft flushable plant litters for fussy paws. Tuft + Paw is cleaner in the air and lower tracking. Catalyst clumps a little loosely but costs noticeably less each day, and that decides it for most homes.

Neither run recorded granules outside the box, ammonia after one day and ammonia after three days, so those rows are left out rather than filled in from a similar bag. The full test data shows every reading we have.
Primary tradeoff: Catalyst Soft Wood's weakest area here is value.
Strongest odor control in this set with fresh wood scent helps.
It is also the cheapest daily option at $0.72 per day.
