Our neighbour has trapped a cat in the woods near us which we think could be ours..(it went missing nearly 2years ago) It is very friendly and has the markings of our cat. We have however another boy cat now and the pair of them want to kill each other but we want to keep both of them. Is there anything I could do. Both cats are neutered and we have 3 others as well but they show no interest in either of the males. Have separated the cats at the moment but would like them all to get on.
