Jewels was one year old and starving when he wrapped around my ankles and squeaked his demand to be rescued. Now he's 5 and two vets wanted to euthanize him because of high fevers and "nothing they could do". He has FIV and Feline Immune System Support has kept him alive and in good shape for the past 6 months. He demands his "goody" wrapped in cream cheese, and seems to know that it is helping him. So grateful to have found it.
