Cat ringworm is mainly caused by Microsporum canis infection. It may also be caused by common fungal infections such as Trichophyton mentagrophytes and Microsporum gypseum. Because cat ringworm is a fungal infection, and fungi are relatively resistant to the environment, cat ringworm has a relatively strong ability to spread. Cat moss is actually a contagious disease. ​​​​​​

Cats can be infected with tinea felis through direct contact and indirect contact. Direct contact means that a healthy cat comes into contact with a sick cat and is infected with cat ringworm; indirect contact means that a healthy cat comes into contact with contaminated items, clothing, etc., and at the same time it comes into contact with the dander and scabs of sick animals, which may also be contaminated. In addition, if human hands are contaminated with contaminants and then come into contact with cats, they may also become infected.

Therefore, for the health of cats, it is recommended to clean the room well, avoid contact with sick animals, and clean hands before touching cats. Cat ringworm is mainly caused by Microsporum canis infection. The clinical symptoms of typical hair loss spots are basically not present. Instead, symptoms such as itching, hair loss, scabs, and increased dandruff appear. It is recommended to seek medical treatment in time.
