Cats should take metronidazole for up to 3-4 days. Improper use of metronidazole can cause symptoms such as vomiting and dizziness in cats. It is recommended that cat owners decide whether to use metronidazole after the condition worsens. Feline stomatitis is an inflammation caused by a lack of certain vitamin B in cats, so cats’ inflammation can be treated by supplementing vitamin B.

When cats suffer from feline stomatitis, their mouths will feel painful. If your cat eats cat food that is too dry or too hard, it will cause damage to the cat’s mouth. It is recommended that cat owners switch to liquid food, which can help the cat eat smoothly and reduce the cat's pain.
