This was such a great thread, I am currently going through the exact same thing!! My 1 year old male just seems to be getting meaner and meaner he gets that crazy look in his eyes and pouches and bites until she screams every encounter they have do you have any tips or advice on what worked for you? Poor little baby girl is so sick of being trapped in this bedroom and is terrified of her big brother! How long did it take before they got along and could co-exist?Thank you to everyone who posted in this thread and got me through this thing. I am happy to say the cats are getting along pretty well now.
