I bet it is hard to want them to be lovey dovey and yet they are not yet. I would buy a laser pen and a few fishing pole type toys, where they need you to be at the other end, to play. They will associate you with the toys. I would also give them treats at the same time. If they didn't have each other, they may have been friendlier too, but it IS nice to have them be happy with just each other for the time being.

My cats go through stages of being friendly and then not so much. They have their moods and rules.

I hope they boys get friendly soon! I would hate to have your heart break!

My advice is play, play, play!

Good luck.
