Cat biochemical examinations are necessary because some cats may be allergic to anesthetics or have liver function problems. Without biochemical examinations, some diseases may be difficult to detect in the early stages. Especially before a sterilization operation, a biochemical examination must be performed. Some cats are allergic to anesthetics and may easily suffer shock during the operation, which may even be life-threatening. Therefore, regular in-depth examinations of cats can help them better understand their health.
