Pretty litter allows you to become alert about potential health problems developing your cat before they get sick. This will help you to save on expensive vet bills by getting ahead of a problem. Some of the health conditions that PrettyLitter can help do to identify include kidney tubular acidosis, Airy tract infections, metabolic acidosis, bladder inflammation, bladder stones, and calcium oxalate problems.  A yellow or olive green color indicates that your cat is healthy. A blue color identifies that is abnormal alkalinity. A dark green color also indicates abnormal alkalinity. Red indicates there's a detection of blood in the urine. Also, orange indicates that there's abnormal acidity in the urine.
