Feline Immunodeficiency Virus: Welfare Management

Feline immunodeficiency virus affects approximately 2-4% of cats globally, causing immune compromise that requires careful management for welfare while many FIV-positive cats live long, comfortable lives.

Key Facts

FIV is spread primarily through deep bite wounds — most common in intact male outdoor cats
FIV-positive cats can live 5-10 years or more after diagnosis with appropriate management
The condition does not spread to humans or other animal species
Vaccination is available in some countries but not universally recommended
FIV-positive cats are frequently euthanized unnecessarily due to misunderstanding of their prognosis

Welfare Considerations

FIV-positive cats with appropriate management, indoor living, and regular veterinary monitoring can live long, comfortable lives with good welfare. Unnecessary euthanasia of FIV-positive cats at diagnosis represents a significant and preventable welfare harm. Welfare management focuses on preventing secondary infections, regular health monitoring, and indoor housing to prevent disease spread and reinfection.

What You Can Do

Neuter all cats to reduce fighting behavior that spreads FIV
Test cats for FIV regularly, particularly those with outdoor access
Never euthanize an FIV-positive cat without veterinary consultation on their individual prognosis
Keep FIV-positive cats indoors to protect them from secondary infections
Support organizations providing education about FIV management and welfare
