Although Pretty Litter's color-changing technology provides valuable information about your cat's health, it is essential to understand that you cannot always rely on this system. The litter may remain its standard yellow or olive-green color even if the cat has health problems that do not affect the pH level of its urine. Conditions such as diabetes, some types of kidney disease, and other health problems unrelated to urination may not cause Pretty Litter to change color. This highlights the importance of regular veterinary checkups and attention to other signs of illness in your cat, such as changes in appetite, activity level or behavior.
