Risk Factors for FIV

Risk factors for feline immunodeficiency virus (FIV) include the following:

  • Age (FIV is more common in older cats.)
  • Aggression (Aggressive male cats that roam and fight with other cats are more likely to be infected than females and non-aggressive males.)
  • Illness
  • Time spent outdoors

The average age of cats with FIV is 5 years at the time of diagnosis. Sick cats are much more likely to have FIV—in the United States, about 15 percent of all cats that show clinical signs of another disease are also infected with FIV.

Free-roaming outdoor cats are more likely to be infected than indoor cats.
