What Can Blue To Deep Green Indicate?
Blue to deep green indicates your cat’s urine is in the high or alkaline pH range. High pH can indicate health concerns for your cat.
Blue/Deep Green = High pH or Alkaline

When you see blue or deep green in your PrettyLitter, it’s an indication that your cat’s urine is within the higher pH range or alkaline level. Blue cat litter can be a sign to monitor your cat’s bathroom habits. Your cat may be experiencing a UTI and have an increased risk of struvite crystal/stone formation. If blue urine appears in your cat’s litter for more than 24 hours, consider contacting your veterinarian.
PrettyLitter’s color-changing technology is designed to give you peace of mind by providing daily insights into your cat’s well-being. If you see the color change to blue/deep green or orange, you should monitor your cat’s litter for the following 48 hours. If blue/deep green or orange continue to appear, you should consult your cat’s veterinarian. If red appears in your cat’s litter box, this means that there is blood in the urine and you should immediately consult a veterinarian.
