So I have 3 guinea pigs, two were bought together at a pet store and are in the same cage (nugget and beanie) . The other one I rescued (Linus) and he is in a separate cage. I quarantined them for a couple of months and slowly introduced them to each other however after a couple of weeks Linus and nugget started fighting. I figured it was a dominant issue at first but then it got nasty and they were biting each other alot. So I separated them, and even put them in separate rooms. Then Linus started wheeking all the time when he would hear nugget and beanie from the other room, wanting to be with them. So I moved his cage into the same room. That was fine for a while but now Linus constantly bites at his cage and chatters his teeth wanting to be with nugget and beanie. I tried to introduce them again but this time blood was drawn and I separated them immediately. I don't know what to do because nugget and beanie get along great and Linus always shows signs that he wants out of his cage to be with them but when I do all they do is fight and I don't want them to get hurt. It's becoming hard to get to sleep at night because he is so loud when he bites the cage. Any suggestions on how I can get this to stop?
