At this time, I have one beautiful little female guinea pig named Oreo. I've had her for about 2.5 years now and she has never shared with another guinea pig. I still have a pretty small cage and am looking for a bigger one, and would also like to add another guinea to my family because I know guinea pigs like to have same-species companions. I was at PetSmart and saw an ADORABLE baby guinea pig, although I now know it is a male. I would consider purchasing it and neutering it so he could bond with my girl, although I don't want to pay to have it done and risk harming him or anything else. So basically I am looking for a female guinea pig now. I also want to make sure that since Oreo has never bonded with another guinea pig (and has been a little spoiled), that she would get along with a new guinea pig, because I don't want to have to put up a cage separator, and I would feel bad for both of them then. Does anybody have any suggestions, advice, feel free to comment, I'll appreciate any advice.
