Q: aggressivness

I have 2 hairless guinea pigs. They are sisters and I have had them for about 9 weeks. One of the guinea pigs gave birth 4 weeks ago and just recently I got rid of the babies as one was a male and there was a lot of fighting going on. This was never the case when I first got the sisters. Now one of the guinea pigs keeps attacking the guinea pig who had the babies. The aggressive on keeps sniffing the other ones butt and biting her and there are numerous scratches on her back. What do I do to eliminate this problem?

A: aggressivness

Usually when a big event happens, like giving birth, this can "upset" the guinea pig's role of dominance, and often the dominant pig will feel the need to try and re-establish dominance again once things have settled. It's very common for these acts to happen, like nipping and sniffing and chasing and even mounting. If your pig is getting hurt in the process however, if things haven't settled down by now you should consider separating them with a wire barrier in the cage. This way they can still see and sniff each other and have company, but cannot hurt each other.

If it's just nipping, let it happen, as that's natural. Hairless guinea pigs are more sensitive since they have no fur, but if things get out of hand, they need to be separated.
