Companion Cat FeLV Management and Quality of Life

Feline leukaemia virus affects thousands of cats annually. Understanding FeLV transmission, progression, and management helps owners provide the best possible quality of life.

Key Facts

FeLV is the most common infectious cause of death in cats globally
Transmission occurs primarily through saliva in close social contact between cats
Approximately 70% of cats exposed to FeLV clear the infection naturally
Progressive FeLV infection leads to immunosuppression and secondary diseases
FeLV-positive cats can live for years with appropriate management and monitoring
Vaccination is highly effective and recommended for cats with outdoor access

Welfare Considerations

FeLV-positive cats can maintain good quality of life with attentive management. Keeping them indoors prevents transmission to other cats and reduces exposure to secondary infections. Regular veterinary monitoring, prompt treatment of secondary conditions, and attention to pain, appetite, and behaviour allow owners to act early when welfare declines, ensuring FeLV-positive cats experience the best possible life.

What You Can Do

Vaccinate cats against FeLV, especially those with outdoor access
Test new cats for FeLV before introducing them to existing cat households
Provide indoor enrichment for FeLV-positive cats who must stay inside
Work closely with your vet to monitor FeLV-positive cats regularly
Consider adopting FeLV-positive cats, who face higher euthanasia rates in shelters
