According to the search results, the color of healthy cat pee is transparent or light yellow, and it has a faint ammonia smell. The urine should not be cloudy or difficult to see through. If the urine is dark yellow, orange, or brown, it could be a sign of dehydration and needs medical attention. If the urine is red, it could indicate a urinary tract infection or kidney disease, and if it is black, it could be a sign of liver disease. Changes in color (dark or light), cloudiness, or particulate matter (floating debris) are most often associated with bladder or kidney conditions. If you notice any change in color, especially red-tinged urine, notify your veterinarian at once.
