Cat Feline Immunodeficiency Virus and Welfare

FIV-positive cats can live long, healthy lives with appropriate management and welfare-conscious care.

Key Facts

Feline immunodeficiency virus affects approximately 2-4% of cats in North America
FIV is transmitted primarily through deep bite wounds — outdoor unneutered males are at highest risk
FIV-positive cats can live for many years without significant illness with appropriate care
Vaccination and neutering significantly reduce FIV transmission risk in cat populations
FIV-positive cats are often unnecessarily euthanized due to misunderstanding of their prognosis

Welfare Considerations

FIV-positive cats suffer welfare harm from disease and, tragically, from unnecessary euthanasia based on outdated prognosis assumptions. Modern understanding is that FIV-positive cats managed as indoor-only cats with good nutrition and preventive veterinary care can live normal, comfortable lives for years. The welfare priority is accurate owner education, adoption of FIV-positive cats from shelters where they are disproportionately euthanized, and integration of welfare-conscious management throughout their lives.

What You Can Do

Adopt FIV-positive cats from shelters where they face disproportionate euthanasia risk
Maintain FIV-positive cats as indoor-only to prevent transmission and protect them from infections
Provide excellent preventive care and monitor closely for secondary infections requiring treatment
Neuter all cats to reduce bite wound transmission in outdoor cat populations
Educate others about the positive prognosis for well-managed FIV-positive cats
