Crystals Health Monitoring Litter

pH-activated Unscented Crystals Litter that Helps You Detect Illness

Fresh Step® Crystals Health Monitoring Litter provides 30-day odor control with Ammonia Block Technology while helping you track your cat’s urinary health. The color-changing crystals detect urine pH irregularities, potentially indicating issues like UTIs, bladder stones, or acidosis. This lightweight, paw-friendly litter absorbs moisture, blocks ammonia, and helps keep the litter box fresh. A color scale on the bag helps you easily interpret the changes, offering valuable insights into your cat’s urinary health and allowing you to address potential concerns early.
