Feline Leukaemia Virus: Welfare and Management Update

Evidence-based management of FeLV-positive cats to maximise welfare and lifespan.

Key Facts

FeLV is spread through close contact — grooming, shared food bowls, bites
Progressively infected cats (latent carriers) can remain healthy for years
FeLV-positive cats are at elevated risk of lymphoma and anaemia
Vaccination is highly effective — all outdoor cats should be vaccinated

Welfare Considerations

FeLV infection causes progressive immune compromise with welfare implications through increased disease susceptibility and eventual immunosuppression. Welfare-focused management keeps FeLV-positive cats indoors or in secure environments, provides rigorous preventive healthcare, and monitors closely for early signs of secondary disease. Many FeLV-positive cats live normal quality lives for years with appropriate management.

What You Can Do

Vaccinate all outdoor cats against FeLV — vaccination is highly effective and welfare-protective
Keep FeLV-positive cats indoors or in secure environments to reduce infection exposure
Schedule 6-monthly health checks for FeLV-positive cats — early disease detection improves welfare
