Introduced second rat- strange behavior?
I have two female rats- the senior, Bella Lugosi, I've had for a few months now and shes had to live by herself in that time. Recently I introduced Lon Chaney, and after finally getting the two to live peacefully in the same cage (Bella was territorial at first), I wondered about a strange behavior I saw. It seemed Lonnie, the younger rat (and half Bella's size!) has been chasing Bella around and crawling around underneath her, literally getting underfoot, ducking under her belly again and again. Does this mean something?
