My girls turn one soon, and I had the recent revelation that whenever they go, they'll likely go near one another. The thought of saying goodbye, and then again, and then again is gut-wrenching. Has anyone had this experience? I have the sense that most forum users have at least two rats close in age to one another. Just looking for some reports about the grieving process, and the effect of the disappearance on the other ratties. I mean...what is it like to be the last rat...?
