Ringworm is a leading cause of shelter cat euthanasia due to treatment intensity, but foster-based treatment programs demonstrate that cats can recover effectively outside shelter environments with better welfare outcomes.
Ringworm euthanasia in shelters represents a welfare failure where treatable disease leads to preventable death, often driven by resource constraints and operational burden rather than genuine welfare necessity. Cats with ringworm are healthy animals with a curable fungal infection — euthanasia reflects inability to provide treatment in the shelter environment rather than irrecoverable suffering. Foster-based treatment programs demonstrate that ringworm can be treated successfully in home environments with less frequent treatment requirements, better welfare for the cat from reduced stress, and higher cure rates from improved immune function in lower-stress settings. Shelters that have developed foster ringworm programs have both eliminated ringworm-related euthanasia and achieved better treatment outcomes, demonstrating that the welfare-positive approach is also the more effective approach.
