Arm & Hammer Health IQ Cat Litter Additive, With Color Changing Health Indicators, 6.5 oz

• HEALTH-MONITORING: ARM & HAMMER Health IQ Cat Litter Additive turns your cat’s favorite litter into a health-monitoring system by detecting pH changes in cat urine
• COLOR CHANGING HEALTH INDICATORS: Easy-to-see indicator crystals change color when irregularities in your cat’s urine pH are detected, which may indicate a potential urinary health condition
• NO SWITCHING LITTER: Simply add to your cat’s existing litter by sprinkling crystals evenly to completely cover the entire surface of a fresh litter box
• RECOMMENDED USAGE: Use with every fresh litter box change or as needed after scooping; for multi-cat households, temporarily separate cats using their own litter box with Health IQ crystals
• UP TO 4 USES: Each 6.5 oz bottle lasts up to 4 uses when used as directed in a 19″x15″ litter pan
