The Cat's Pride Ultra Health Monitor gives you the tools to actively monitor your cat's wellbeing from the comfort of your home, all within a high-performance unscented micro-crystal litter. This innovative litter uses advanced pH indicator technology to change colors when early signs of potential urinary health issues appear. Our easy-to-understand color key gives you instant results: deep yellow-to-orange signals low (acidic) pH, olive green-to-yellow represents standard range, and blue-to-dark-green alerts you to high (alkaline) pH. Red granules provide an immediate visual cue of potential blood, prompting you to contact your veterinarian immediately. Beyond its critical monitoring function, Cat's Pride Ultra offers powerful 30-day odor control, is 99% dust-free, and is 60% lighter than traditional clay alternatives. Get a full month of proactive feline health monitoring and clean-home performance in every 5 LB bag.
