Ringworm is contagious. It spreads when you have skin-to-skin contact with a person or animal that has it. It can also spread when you share things like towels, clothing, or sports gear. You can also get ringworm by touching an infected dog or cat, although this form of ringworm is not common.
Several different fungi found throughout the world can cause ringworm, however, the vast majority of cases in cats and dogs are caused by Microsporum canis, Microsporum gypseum, or Trichophyton species. The fungus is most commonly found either on an infected animal or in the living quarters of infected animals.
