Take these three adorable kittens for example. Siblings Duffy, Cliffy and Muffy are sweet, inquisitive and fluffy but they tested positive for FIV and have been deemed unadoptable."FIV stands for Feline Immunodeficiency Virus. It's a lentivirus, meaning that it progresses very slowly, gradually affecting a cat's immune system. It is passed through blood transfusions and through serious, penetrating bite wounds - mainly by stray, intact tom cats. The most well-known lentivirus in humans is HIV. But the two are not at all the same, and you can't get FIV from a cat. In fact, the only thing about FIV that you can catch is a bad case of the rumors.
As long as cats with FIV are not exposed to diseases that their immune system can't handle, they can live perfectly normal lives. "
