Your cat may have serious gingivitis and tartar and tooth infections. She also may have mouth ulcers. Either cause will make her drool and is very painful. She needs to eat, as not eating in itself can cause serious liver damage. Please take her to a veterinarian today for an exam. Sometimes cats also come in contact with chemicals, that damage the mouth, and hurts. Kidney failure can also cause serious mouth ulcers.
