There was another forum that my wife and I were members of but cannot find it any more so here I am.
We just got two little ones today (4-6 weeks) from a pet store. (I know its not the best place they mixed a female in with males and well...) So we decided to take two males home with us.
We took a year break from rats and decided that it was time to get some more little guys.
Well I know one guy is a guy but the other one that I am 90% sure is a male well im not so sure. I have read that even after they drop they suck them back in at times. But its just worrying me because I am not 100% sure if the one in question is a male or not. As much as I love rats I would prefer to leave the breeding to others.
