Im getting another guinea pig.. i have a question?

OK you say SHE, Sammy, has been alone, so i am going to have to go with it really is a girl. Female guinea pigs are much more willing almost welcoming to have a cage mate as where male almost always fight. So we are going on the information the Sammy is a she and i am going to say she will be most happy to have a mate. Just do not being home one that is older then her, make it one that is younger then her and you will not have any problems.
