The best and most effective treatment to adjust a cat’s urine pH is to start a special prescription diet. Royal Canin, science diet and Purina all make prescription diets with additives to make the urine more acidic. This will also help to prevent urinary tract infections. These diets can be purchased in many pet stores and online as well but they do require the OK from your veterinarian. The diets will begin to take affect within two weeks and it is recommended to retest the urine one month after starting the new diet. I hope this helps.
