Feline AIDS works much like the human variety, weakening cats' immune system and making them susceptible to infections of the skin, eyes, nose, mouth and urinary tract as well as more serious ailments like cancer and kidney failure. The disease typically stays latent for years, with cats becoming ill later in life.

FIV is frequently confused with the feline leukemia virus (FeLV), which also attacks the immune system. But FeLV can be spread through casual contact between cats, and while cats with FIV can have normal life spans, those with FeLV often die within three years of becoming infected.
