Cats can develop something called gingivostomatitis as well as feline oral resoptive lesions. These are both very painful and require antibiotics and sometimes steroids as well as dental procedures to correct. Also if there's any possibility she chewed something like electric cord or plant that can calls the signs as well. I recommend Dusk be checked out by a veterinarian as soon as possible. This is to prevent her from becoming dehydrated and malnourished from not eating. Do not give her any human medications as they are very toxic to cats and I'll make the situation worse.

    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.

    It is possible she may have a degree of periodontal disease. An exam with a veterinarian is recommended for confirmation. She may need a dental cleaning and she may lose teeth. You will need to keep her confined afterwards until she recovers.
