I had a trio of female guinea pigs for 2 years up until March when one died, and a month ago one one died. Now I'm left with one 3 year old. I've left a mourning period and now she seems ok. I Don't know if I should get her a friend. I know guinea pigs need company but they can also fight when reintroduced. My mum and dad don't want another one. They also didn't care that they needed a bigger cage when it wasn't even big enough for one. I don't think they want us to have any more piggies but still the welfare of the girlie we still have is most important, to me anyway. Any advice on what I can do?
