Arm & Hammer Health IQ Litter Additive, 6.5 oz

Health IQ™ Crystals turn any litter into a health-monitoring litter, so you get the best of both worlds — the clumping and odor performance of your favorite litter, plus indicators of your cat’s urinary health. Easy to See. These indicator crystals quickly change color when irregularities in your cat’s urine pH are detected, which could indicate a possible health issue.
Turn your litter box into a health-monitoring system to help keep tabs on your cat’s health without switching from your favorite litter.
Requires less product to show color without impact to litter clumping performance
