Cat Ringworm Prevention Multi-Cat Households

Ringworm (dermatophytosis) spreads rapidly in multi-cat households and rescue environments, causing skin lesions and intense itching while also posing zoonotic risk to humans.

Key Facts

Ringworm in cats is caused by Microsporum canis in the majority of cases
Kittens and immunosuppressed cats are most susceptible to clinical disease
Infection can spread to humans causing circular skin lesions
Spores survive in the environment for up to 18 months complicating elimination
Lime sulphur dips and oral antifungals are effective treatments when used consistently

Welfare Considerations

Ringworm causes skin irritation and stress, particularly in kittens. Environmental decontamination alongside individual treatment is essential to break the cycle of reinfection.

What You Can Do

Isolate newly acquired cats before introducing them to resident animals
Maintain strict hygiene in multi-cat households to limit environmental contamination
Seek veterinary diagnosis and treatment early to prevent spread
Inform household members about zoonotic risk and protective measures
