Give Your Litter Health IQ™

For litter box PURRfection and cat urinary health monitoring, use HardBall™ Litter with our NEW ARM & HAMMER™ Health IQ™ Cat Litter Additive. You’ll combine no-mess odor performance with indicator crystals that detect irregularities in your cat’s urine pH.

This product does not replace wellness exams, veterinarian diagnosis or detect all urine abnormalities. If you suspect a health issue with your cat, consult your veterinarian regardless of pH results from this product. For best results, do not combine Health IQ crystals with other additives containing zeolites or baking soda as this may compromise color indicator accuracy. Works best with small particle size cat litters. Store in a cool dry place.
