Hi! We are new this....We have 2 male guinea piglets. We bought them as babies from the pet shop. The have never been really friendly but have tolerated each other, with quite a lot of rumble strutting and mounting. One was obviously dominant. Last week they started to chitter loudly at one another. Theh chased each other and eventually started properly fighting. There was no obvious sign of injury, but both piglets seemed traumatised afterwards. Lots of hair had been pulled out. We separated them and let them calm down. Now, their cages are joined but with a door that can be closed. During floor time yesterday they had another fight. They are chewing on the bars between the cages constantly. They seem to be chatting. As soon as we let them be together, they fight. Its worth mentioning that the previously submissive pig now seems to be becoming dominant.... They are about 5 months old. They were living together in a big pen with lots of hidies. They are brilliant piggies and have become really tame. Our kids love them. We dont want to have to keep them apart really. What can we do? Will they ever be friends? Help please!
