It took my girls 6 months to stop running from each other. I have a perch on the outside of their cage, so when ever Luna would get on there for scritches, I would pet her until she closed her eyes and then slowly move Jupiter closer and closer to her and pet them both with the same hand until they were touching. Its kind of hard to explain, lol.They were both receiving love from me, but also very close, if not touching each other. After a little while they would nuzzle each other while I was petting them. It seemed to break the ice between them and now they have a lovely relationship. You just have to be ready to move the other away at the first sign of aggression.
