Hi everyone - I think this is really a vet question, and we have been to a vet, but I'm living overseas and while the vet I saw had pretty good English, I still kind of wonder if some things were a bit lost in translation. DH and I just took in a stray who is probably about 3-4 months old, and when we took him to the vet for his shots they ran a blood test and told us that he has feline leukemia. The vet also told us that because of this he needs to be kept away from other cats. The problem is we already have another cat, so of course this complicates things. Our other cat has already been vaccinated for leukemia years ago, but the vet here told us that the vaccine may not be 100% effective and that our cat could still contract the illness. Is this really true? Or can we be pretty confident that the old cat will be well protected by the vaccine? Has anyone else had experience with feline leukemia who could give any other general advice? Thanks!
