My cat is 19 months old, female and has unfortunally FIV. Every 2 months she has a slight breathing problem, which has been taken under control via vaccines by the vet. She lives indoor, there is no other cat at home. I'm really confused about letting her spayed, as I'm afraid that she would have serious problems after the operation. My vet said that she will wake up after the operation, but there could be some infections (lungs, etc), which may occur after the operation. He said that she better should be spayed, but there is always health risques for FIV cats. I asked some friends, who looks after many cats, all of them said that I better forget this operation as it is too risky. My first cat was unspayed and I lost her due some kidney problems at the age of 18, I mean she didn't experienced any sickness such as brest cancer, uterus infection, etc. However my sisters cat died because of breast cancer although she was spayed. I don't know what to do? I'll be glad to have some comments about the risques of any kind of operation for FIV cats. Thank you.
