Here is my delima. Cat next door is positive for Felv and is in the late stages. Freaks me out because my cat use to play and fight with him, and share a water bowl! I have the one I just referred to and is indoor/outdoor, and I have an indoor only, and the past 2 weeks have a stray moved in with us and he looks healthy. Anyway I called vet about my Felv concerns and he said he is less worried about the Felv cat nextdoor and more concerned about one moving in that is unknown. My cats are all current on shots, and he said they should be o.k. I am taking the stray in Saturday for blood tests and vacines. Should I be worried about my cats getting Felv from neighbor cat and not acting faster to vacinate the stray and keep it away from my cats? I am worried worried worried! My babies are only 22 months, and 5 years. Linda
