Neutering male cats is one of the most effective ways of limiting inter-cat aggression. There are no guarantees, but castration is definitely the first and best thing worth trying. If you are worried about the two cats hurting one another, I would keep them separated for the time being. Even after the castration there will still be some residual hormones left in the body for a short while. I would consider keeping the two separated for at least a week or two post-operatively before reintroduction. Hope this makes sense.
