Scab-like things on the cat's neck are most likely to be suffering from cat ringworm, and may even appear hair loss, dandruff and other symptoms. After discovering the cat, the owner should isolate the cat to prevent infection and take the cat to the pet hospital. During the examination and treatment, the cat should wear an Elizabethan ring. The home environment and items used by the cat must be thoroughly cleaned and disinfected to avoid virus residues that may endanger the life and health of the family and the cat.
