Feline Immunodeficiency Virus (FIV)
As its name suggests, Feline Immunodeficiency Virus (FIV) is closely related to the Human Immunodeficiency Virus (HIV) responsible for causing AIDS in people. There is no cure for either disease and the virus causes the gradual destruction of the white blood cells needed to protect the body against infectious diseases. However, the two viruses will only survive inside normal host species - in other words, there is no risk of humans catching FIV from a cat, or vice versa.
