I had a call about a pair of female guinea pigs, kept together in large housing with loads of floor time, one 'normal' piggy and one that has always had a bit of a temper and picked on the other guinea pig but nothing to serious until recently. I take it from the call that the grumpy guinea pig is the dominant one. She had a few days before given the other guinea pig a nip and then suddenly a few days later attacked her fairly badly, aparently the pig has cuts and swelling, advised to take to vet in case there's an infection. Anyhow, the callers vet suggested it could be because she may be coming into season, has anyone any other ideas. The grumpy guinea pig obviously was giving warning signs before she went for the full on attack, I've never heard of such aggression with females before and was wondering if anyone has similar stories? Our own girls have never fought, the odd grumble or push out of the way to get at food so I don't really have the experience of fighting females. The owner is keeping the pigs and sounds like aside from the pig attacking the other one they are very well looked after and spoilt. They aren't housed together anymore obviously and have suggested C&C cages so they can still see each other. So, anyone have experience with fighting females?
