Hi, so I'm a new guinea pig owner. I have only had my two guinea pigs for 5 months now. About a week ago my two boars got into a nasty fight and sadly blood was involved. (A bite to the side, but it has healed since then.) Luckily I was there to break the fight up so nothing worse could happen. I'm not sure as to why this happened. I have read where it happens if they live in a cramped space, but I had them living in a 2x4 C&C cage at the time the fight broke out. I really didn't see this coming, so now I have them living seperate. I know guinea pigs are social creatures and thrive better if they have a partner, so having them live alone has definitely changed how they both act. They don't seem like their usually perky selves now. Neither seems happy alone, but I wouldn't dare put them back together after that fight happened. I am at a total loss as where to go from here. I really need some advice.
