1) Begin with a clean litter box.
2) Using disposable gloves scrub the box with a mild detergent and thoroughly rinse and dry. Avoid using ammonia or other strong cleaners as the residual smell can deter litter box use.
3)Fill the litter box with the cat's normal litter.
4)Spread the Health Indicator evenly across the top of the litter.
5) Watch your cat for litter box visits.
6) Shortly after the cat leaves the litter box check the urination spot for color changes.
7) Compare the color at the urination spot with the colors on the card enclosed in each Health Indicator bag.
8) If the color compares with a color that indicates a high pH (blue or green) or a low pH (red or orange) then contact your cat's veterinarian for advice.
9) If the color indicates normal pH (light gold to light olive) stir the Health Indicator into the regular litter where it can help with odor control for up to a month.
