I have fostered cats with FIV and they DO NOT have to be PTS. If he can get healthier and regain some weight, he could live a full and healthy life. Please give this poor boy a chance. FIV is not a death sentence, it's only one if you make it one.

My kitty, Honeybun, has FIV. I've had him for about 5 years, and he's about 15 years old, if not a bit older. He has had FIV for years and years. It is NOT easily transmissable, and once a cat is healthy, they can live full lives. Give your guy a chance, please. Many vets will just say to put them to sleep, but that does not have to be the alternative. Most live full, very healthy lives. It's only when they contract something else that their immune system has a hard time dealing with it. Get him healthy, to a good weight, and he'll make you a very happy FIV+ kitty owner.
