A cat that has scab-like things on its toes may be suffering from cat ringworm. Cat ringworm is contagious to a certain extent. Once discovered, the cat should be isolated and then taken to a pet hospital for examination and treatment. The places where the cat has been and the items used must be thoroughly cleaned and disinfected to avoid bacterial residues that may affect health. During the treatment, the cat should wear an Elizabethan ring to prevent the cat from licking the medicine and causing poisoning.
