About this condition

Feline immunodeficiency virus (FIV) progressively damages the immune system, leading to opportunistic infections and chronic disease. Transmission occurs mainly through bite wounds; FIV does not infect humans.

Common symptoms

  • Recurrent stomatitis and gingivitis
  • Chronic weight loss
  • Recurring respiratory or digestive infections
  • Neurological signs (late stage)

Common causes

  • Infection with feline immunodeficiency virus (FIV)
  • Bite wounds from infected cats
  • Outdoor territorial fighting
  • Vertical transmission from mother to kitten (rare)

Prevention (husbandry & daily care)

Keep cats strictly indoors to eliminate bite wound risk, test and quarantine new cats before introduction in multi-cat households, and spay/neuter to reduce territorial aggression.
