Tear ringworm on cats’ feet should be treated promptly. First, buy saline solution and cat ringworm medicine. Use the salt water to clean it first, then apply the medicine. Give the cat vitamins during treatment. During this period, the cat can get more sun exposure to help the skin grow quickly. If a cat has ringworm on its feet, it should wear an Elizabethan ring to prevent the cat from scratching and licking it from spreading to the whole body.
