Grayci an outside stray I've been feeding for almost a year went to the vet today because she had a hole under her arm from an abscess. While there I learned "she" is a neutered male and tested positive for FIV..... my heart was broken. I planned to bring him in after this. When I returned home I let him outside.. made me feel terrible but I have 3 other cats inside. No shelters will take him and I don't know what to do. I feel life outside will end his life quickly, but I'm scared to death he could bite one of my other cats as they rough play a lot. He's very sweet and timid... I'm at a total loss on what to do. Can anyone provide some advice? Anyone with a fiv positive cat living with non positive cats?
