What Can Orange Indicate?
Orange indicates your cat’s urine is in the low pH or highly acidic range. Low pH can indicate health concerns for your cat.
Orange = High Acidity
When you see orange in your PrettyLitter, it indicates that your cat’s urine is in a high acidity range. Orange cat litter can be a sign to keep an eye on your cat’s bathroom habits. Elevated acidity may be an early indicator of conditions like metabolic acidosis or kidney issues. If the orange color lasts for more than 24 hours, consider reaching out to 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.

What Is High Acidity?

An orange color in your cat's litter box suggests higher acidity, typically indicating a pH level below 6.0. This can be an early sign of conditions like metabolic acidosis or kidney tubular acidosis and may increase the risk of calcium oxalate crystal formation. PrettyLitter’s innovative formula helps you monitor these changes, providing an early warning system to ensure your cat’s health is always a top priority. By detecting shifts in pH levels, PrettyLitter empowers you to take proactive steps in maintaining your cat's well-being.
