Our babies are now sharing the house! No fights, no puffed tails, nada. Freedom, you are correct once more. We decided to let them work it out, and the little girl, Mau Mau, is Alpha Cat. She is all of 7 pounds and Buddy weighs about 15, yet she can back him into a corner with just a look! He follows her around and lets her set the pace, it's so funny. He wants to play with her very badly and she just gives him this annoyed look. We are still not letting them be alone together when we are not home, not yet. But they seem to be sharing the house very nicely. I want to thank all of you for your advice! You have helped us make this transition very painlessly.
