American Shorthair Cat

　　The pathogen of ringworm is a fungus that can infect humans. It is called ringworm due to the circular coin-shaped hair loss. Sometimes, it causes dandruff on the head, ears, feet, and back, forming hard scars, nail deformities, scaly spots, or no symptoms at all.

　　This disease must be diagnosed and treated by a veterinarian. Additionally, the sick cat’s bedding, belts, collars, and other items must be thoroughly disinfected to prevent spores from remaining and continuing to infect cats or humans. (Source：PetsZone)
