Arm & Hammer HardBall is the strongest all-around pick in this comparison for fast hard clumping on a mid-range budget.
A dependable grocery-store clay option with decent clumping, a noticeable fragrance profile, and fair everyday value.
Fast-forming hard clumps with baking soda odor help, making it a strong mid-range clay pick if you can tolerate moderate dust.
HardBall clumps harder and holds together better in the scoop. Fresh Step is cheaper and easier to find on a supermarket shelf. Both are scented clays that put plenty of dust in the air, so this is a clump-strength decision.
