Feline immunodeficiency virus (FIV)

Testing and ongoing care help guide the next steps.

FIV affects a cat’s immune system. Some infected cats have no obvious signs for a long time, while others develop recurrent illness. An appearance or symptom list cannot establish FIV status.

A veterinarian interprets testing in the context of exposure and health history and helps plan ongoing care.

Common signs

May have no obvious signs; recurrent infections or changes in general health

When to contact a vet

Discuss possible exposure, persistent illness, or a positive screening result with your veterinarian.
