Turn your existing cat litter into a health-monitoring system* with ARM & HAMMER Health IQ Cat Litter Additive. Crystals change color by detecting pH changes in your cat’s urine, which may indicate a potential urinary health condition and alerting you to consult a veterinarian. Simply add an even coating to completely cover the entire surface of a fresh litter box. After your cat urinates in the litter box, wait at least 4 hours. Then, refer to the color indicator chart on the bottle. If colors outside the yellow/green range persist and/or your cat seems distressed, consult your veterinarian. Repeat use with every newly filled litter box or as needed after scooping. *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. Each 6.5 ounce bottle lasts up to 4 uses when used as directed in a 19”x15” litter pan. Works best with small particle size cat litters. Store in a cool dry place.
