Ringworm (dermatophytosis) causes skin disease in cats and is transmissible to humans - treatment is prolonged and welfare considerations are significant.
Ringworm treatment involves significant welfare compromise through the treatment process itself, particularly with repeated lime sulphur dips. Oral antifungal treatment is less aversive where effective. Preventing ringworm in shelter environments through rapid diagnosis, isolation, and treatment is the most welfare-conscious approach.
