I adopted a "female" guinea pig from Petco a couple weeks ago. She has been very scared and I was finally able to pick her up today. I noticed "she" has HUGE BALLS. I'm so mad because I thought she was a girl this whole time and have been calling her little girl and gave her a girl name. I called the petco and asked them if it is normal for female guinea pigs to have balls?! They hung up on me. I called back and explained to them that they sold me a guinea pig and told me it was a girl but it seems very much like a boy because he has big testicles, I can tell the guy got very uncomfortable whenever I mentioned balls for some reason . He got very mad and told me that it doesn't matter if it's a boy or girl because you're supposed to take care of them the same way. I explained to him that it's not ok that they told me false info that he was a female and I've already given him a female name and he just told me that it doesn't matter that they mistook him as a femals. What if I had another female pig and wanted to get a female to make sure they didn't mate and then they ended up having babies (which I don't have time to take care of babies) all because they told me false info? The manager at petco is making it seem like its no big deal and it doesn't matter. What's your opinion ? Also I've had him for 2 weeks now and he is still very scared and making noises all the time. I have no idea how to calm him, when I pick him up he starts crying and biting my shirt or my arm (not hard) . why is he not comfortable yet? Will he ever get used to me?
