Cat Feline Immunodeficiency Virus: Long-term Management

FIV-positive cats can live long, comfortable lives with appropriate management. Understanding the virus, its transmission, and welfare implications helps owners provide informed care for affected cats.

Key Facts

FIV is transmitted primarily through bite wounds between cats — casual contact, shared bowls, and grooming do not spread the virus
An estimated 4-7% of UK cats are FIV-positive, with intact male outdoor cats at highest risk
FIV-positive cats progress through asymptomatic, symptomatic, and AIDS-like stages over months to years
Many FIV-positive cats live for 5-7 years or more after diagnosis with appropriate supportive care
FIV is species-specific and cannot be transmitted to humans or other non-feline species
Neutering and keeping FIV-positive cats indoors prevents onward transmission and reduces their own exposure to pathogens

Welfare Considerations

FIV-positive cats were once routinely euthanased at diagnosis, representing a significant historical welfare failure. The understanding that FIV-positive cats can live long, comfortable lives with appropriate management has changed this picture substantially. The key welfare intervention is prompt treatment of opportunistic infections, reduction of stressors, and monitoring for immune decline. FIV status should inform management decisions, not result in automatic euthanasia.

What You Can Do

Keep FIV-positive cats indoors to prevent transmission to other cats and protect them from infections
Neuter FIV-positive cats to reduce roaming behaviour and infection transmission risk
Schedule 6-monthly veterinary check-ups including blood and urine testing for FIV-positive cats
Treat any secondary infections promptly with veterinary guidance
Never euthanase a healthy FIV-positive cat based on diagnosis alone — discuss prognosis with your vet
Consider rehoming FIV-positive cats with other FIV-positive companions to allow safe social contact
