Cat FeLV Management and Welfare

Feline Leukaemia Virus (FeLV) causes immunosuppression and cancer in cats, with improved management enabling many infected cats to live good quality lives for years.

Key Facts

FeLV is transmitted through close contact including mutual grooming and shared bowls
Approximately 20-30% of infected cats become persistently infected and immunosuppressed
Modern management includes preventing secondary infections and monitoring for lymphoma
FeLV-positive cats should be kept indoors to prevent transmission and protect from infections
Vaccination is highly effective and recommended for all cats with outdoor access

Welfare Considerations

FeLV causes progressive immune failure but management has improved significantly. Infected cats can live comfortable lives with appropriate care and monitoring.

What You Can Do

Vaccinate all outdoor cats against FeLV routinely
Test cats for FeLV status before introducing them to a multi-cat household
Provide supportive care and regular monitoring for FeLV-positive cats
Support rescue centres with appropriate FeLV management protocols
