Ringworm (dermatophytosis) is a highly contagious fungal infection that challenges cat welfare in shelters, often leading to euthanasia when not managed systematically.
Ringworm creates a significant welfare crisis in shelters. Without systematic protocols, it spreads rapidly, often triggering mass euthanasia of affected cats. Yet with appropriate treatment — antifungal baths, oral medication, and environmental cleaning — almost all cats recover fully. The barrier to better outcomes is typically knowledge and resources, not medical impossibility. Foster-based treatment programs dramatically reduce shelter ringworm euthanasia by getting cats into controlled home environments. The fungal spores are highly persistent in the environment, requiring thorough decontamination. Human caregivers, especially children and immunocompromised individuals, should take appropriate precautions.
