Cat bladder stone surgery can easily lead to cat kidney failure. Some cats are allergic to anesthetics and may not wake up after the surgery. Therefore, it is best to have a physical examination before surgery to see if the cat is allergic to anesthetics and whether the cat is in good health. Usually, cats should drink more water and urinate more, especially male cats. Clean the litter box in time to keep the litter box clean and hygienic to avoid bacterial infection.
