Cat FIV: Management, Welfare, and Adoption Considerations

Feline immunodeficiency virus (FIV) affects cats worldwide, causing chronic immune suppression. With proper management, FIV-positive cats can live long, healthy lives and make excellent companions.

Key Facts

FIV affects approximately 2.5-4.4% of healthy cats globally; rates are higher in free-roaming and feral populations
FIV is transmitted primarily through deep bite wounds; casual contact and shared food bowls pose minimal transmission risk
FIV-positive cats can live 10-15 years with good veterinary care and indoor management
The virus progresses slowly; many cats remain asymptomatic for years before immune compromise becomes apparent
FIV-positive cats are often overlooked in shelters, leading to higher euthanasia rates despite good prognosis
An FIV vaccine exists but is not universally recommended due to interference with testing and variable efficacy

Welfare Considerations

The welfare implications of FIV are twofold. First, infected cats require attentive management: regular vet check-ups, prompt treatment of secondary infections, dental care, and indoor or controlled outdoor access to protect both their own health and other cats. Second, FIV-positive cats suffer a welfare deficit in shelter systems where they are systematically underadopted or euthanised based on stigma rather than prognosis. Education campaigns have successfully increased adoption of FIV-positive cats in many regions, demonstrating that attitude change is achievable. Cats in stable indoor homes with no bite-risk contact with FIV-negative cats pose negligible transmission risk.

What You Can Do

Consider adopting an FIV-positive cat and providing the attentive indoor care they need
Share accurate information about FIV to reduce stigma and improve shelter adoption rates
Desex cats to reduce fighting behaviour and FIV transmission in free-roaming populations
Schedule regular vet check-ups for FIV-positive cats to catch secondary infections early
