Ringworm (dermatophytosis) in cat shelters causes welfare harm through treatment protocols and is a major driver of extended shelter stays and euthanasia, with evidence-based protocols dramatically improving welfare outcomes.
Ringworm welfare in shelters illustrates how protocol design affects both medical outcomes and animal welfare. Traditional approaches - quarantine in isolation rooms with intensive topical treatment - extended shelter stays, delayed socialization, and increased stress for affected cats. The UC Davis foster-based approach produced dramatically better outcomes by placing cats in stimulating home environments during treatment, reducing stress that impairs immune function, and reducing shelter burden simultaneously. The welfare case for evidence-based ringworm management is compelling: faster cure, shorter shelter stays, better socialization, and reduced euthanasia all represent welfare improvements achievable through protocol change without additional resources.
