Companion Cat: Ringworm Treatment and Prevention

Ringworm (dermatophytosis) is a fungal infection causing skin and hair loss in cats, requiring systematic treatment to resolve and prevent spread to other animals and people.

Key Facts

Ringworm in cats is caused by Microsporum canis in approximately 90% of cases
Clinical signs include circular areas of hair loss, scaling, and crust formation
Kittens and immunosuppressed cats are most susceptible to severe infection
Treatment requires both topical antifungal application and systemic oral treatment for 6-8 weeks
Environmental decontamination is essential as spores survive in the environment for months

Welfare Considerations

Ringworm causes skin irritation and itching that impairs quality of life, and untreated infections can spread extensively. The systemic treatment required is prolonged and stressful for cats. Prevention through good nutrition supporting immune function and appropriate quarantine of newly acquired cats reduces both the welfare impact and zoonotic transmission risk to human household members.

What You Can Do

Quarantine new cats and kittens for two weeks and check for skin lesions before introduction
Seek veterinary diagnosis of any circular skin lesions in cats before treating
Follow the complete treatment course as directed even when lesions appear resolved
Wear gloves when handling infected cats and wash hands thoroughly afterwards
Clean and disinfect all cat bedding, brushes, and surfaces during treatment
