Cat FIV Management and Welfare | Animal Welfare Hub

Feline Immunodeficiency Virus is a manageable chronic condition in cats that, with proper care, allows affected cats to live long and comfortable lives.

Key Facts

FIV is a lentivirus that gradually weakens the immune system, transmitted primarily through bite wounds
Many FIV-positive cats live normal lifespans with few or no symptoms when kept indoors away from infection risks
The virus is species-specific and cannot be transmitted to humans or other non-feline pets
Annual veterinary check-ups are recommended to monitor immune function and treat secondary infections promptly
A vaccine previously available in some countries was discontinued; current management relies on supportive care

Welfare Considerations

FIV carries a significant stigma that leads to high euthanasia rates in shelters. Many FIV-positive cats are healthy and have excellent quality of life for years. The greatest welfare harm comes from misinformation leading to unnecessary euthanasia of adoptable cats. With proper indoor management and veterinary monitoring, FIV cats thrive.

What You Can Do

Adopt an FIV-positive cat — they make excellent companions and can live alongside FIV-negative cats with low bite-wound risk
Keep FIV-positive cats indoors to protect their immune system from infections and prevent transmission
Schedule biannual vet check-ups to catch and treat opportunistic infections early
Advocate in your community for shelters to clearly communicate that FIV is manageable, not a death sentence
