As some of you might already know, I have two lovely little girls. They're probably around 13 weeks now. They are so loving and social. I am so happy with the girls I have...I was just wondering at what point should I add on to my mischief? Do you think that it would be good for them to have an additional playmate or two? I would almost certainly adopt a pair because I know that the introduction process takes a while. I know this isn't really a question with a definite answer, I'd just like to hear your stories and suggestions about how you went about getting your second round of ratties.
