Ringworm (dermatophytosis) is a fungal skin infection common in cats, particularly shelter cats, requiring prolonged treatment that itself poses welfare challenges for affected animals.
Ringworm creates a welfare dilemma in shelter settings: the treatment process itself — repeated dipping, oral medication administration, and isolation — causes significant stress to cats, particularly kittens who would benefit most from socialization during their critical developmental window. Prolonged isolation for treatment compounds welfare harm by preventing normal social and environmental development. Yet untreated ringworm causes skin lesions, pruritis, and hair loss. Low-stress treatment protocols using antifungal showers rather than lime sulfur dips, combined with foster placement to prevent isolation-induced harm, represent the current welfare best practice.
