Arm & Hammer HardBall is the strongest all-around pick in this comparison for fast hard clumping on a mid-range budget.
The best litter under $15 if you need simple clumping performance and broad availability more than premium dust control.
Fast-forming hard clumps with baking soda odor help, making it a strong mid-range clay pick if you can tolerate moderate dust.
Same brand, two different jobs. Super Scoop is the price pick. HardBall is the one whose clumps come out in one piece instead of three. Pay the small difference if you are scooping a busy box every day.
