Feline immunodeficiency virus (FIV) is a virus that affects cats and weakens their immune system. It’s similar to HIV in humans, but it’s important to note that FIV cannot be transmitted to humans.

Cats with FIV may appear healthy for years, but eventually they become more susceptible to infections that a healthy cat would fight off easily. There is no cure for FIV, but with proper care, cats with FIV can live long and happy lives.
