Cat Feline FeLV Prevention Advanced

Advanced FeLV prevention strategies integrate vaccination, testing, and population management to minimize disease burden.

Key Facts

FeLV vaccination provides good protection but is not 100 percent effective
Testing all cats before introducing them to FeLV-negative households prevents infection spread
Outdoor cats in areas with high feral cat density face the greatest exposure risk
FeLV-positive cats can live good quality lives for years with appropriate supportive care
Vaccination of community cats in TNR programs reduces FeLV prevalence in feral populations

Welfare Considerations

FeLV-positive cats develop immunosuppression and malignancy that cause significant welfare compromise over months to years. Prevention through vaccination and testing is far more welfare-effective than managing established infection.

What You Can Do

Vaccinate cats at risk of FeLV exposure especially those with outdoor access
Test all new cats for FeLV before introducing them to other cats in the household
Support TNR vaccination programs that reduce FeLV prevalence in community cat populations
