Cat Ringworm in Shelters: Control and Welfare Impact

Dermatophytosis (ringworm) spreads rapidly in shelter environments, causing welfare problems for cats and significant management challenges.

Key Facts

Microsporum canis causes the majority of ringworm cases in cats
Spores survive in the environment for up to 18 months without treatment
Lime sulphur dips are effective but stressful for affected cats
PCR testing enables faster identification of infected cats than culture methods

Welfare Considerations

Ringworm causes skin irritation and immune suppression. In shelters, outbreaks cause mass quarantine and reduced adoption, with significant welfare costs. Environmental decontamination and fast diagnostic protocols reduce duration of suffering.

What You Can Do

Isolate new shelter cats appropriately to prevent ringworm transmission
Use UV lamp (Wood's lamp) screening for Microsporum canis fluorescence
Support shelter management programmes that include ringworm control protocols
