Ultra Monthly Monitor helps detect Feline Lower Urinary Tract Disease (FLUTD). Simply add to their cat litter and notice the color after your cat uses the litter box. Compare the color of the crystals to the colors on the pH chart on the bag. Early detection allows you to give early treatment before serious problems arise. Works with all litters.
Directions for use: Each month spread the entire contents over the top of clean litter. Shortly after your cat urinates, compare the color of the crystals to the colors on the pH chart on the bag. For low or high pH, consult your veterinarian. If normal, monitor again in 30 days.
