Arm & Hammer Health IQ Cat Litter Additive with Color Changing Health Indicator
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 alert 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.

I added the additive to my litter box and waited 4 hours after my cat used it. The color was within the yellow-green range, which gave me peace of mind. It’s easy to use and helps me stay aware of any changes in my cat’s health.

The additive works well and the color change is noticeable. I check it regularly and have noticed a few instances where the color shifted slightly, which prompted me to consult the vet. It’s a helpful tool for monitoring urinary health.
