I was wondering about the relationship of two of my rats...they wrestle quite a bit with each other(of course only playing, it's hilarious). There's a tiny, tiny squeak here and there very so often but each evening they really go at it. They get along just fine and I've never noticed any sort of blood or bad result of the battles. I know baby rats wrestle quite a bit from personal experience but these guys are adolescents(2-4 months) and still love to wrestle. Do any of your older rats still wrestle for fun? Do you think this means these two rats are the best of friends, or are they actually fighting for alpha rat? I can't really tell if they sleep together because the entire group sleeps together...but yeah...just wanted to know what it means exactly. They're two of my favs also...that'd be cool if they are very closely bonded.
