I am really concerned about my rats fighting. Its really not even fighting. It's increditbly one sided. Basically my older rat beats the crap out my new baby rat. I have a 4 month old that I have had for about 2 months. I just got a 5 week old that I brought home 3 days ago and the poor thing is being beaten. Snakie, the older one, randomly approaches Oreo, the baby, and smacks her. Sometimes they wake me up in the middle of the night because Oreo is squeaking so loud. I feel so bad for Oreo and really angry at Snakie. They do not groom each other and it looks like it has gotten to the point where Oreo runs and hides in corners whenever Snakie is around. I don't want them constantly fighting, because they are keeping my up at night, but also because Snakie should learn to play nice. What do I do?
