I have a one year old female guinea pig and a 4 year old female guinea pig. They have a lot of space both indoors and outdoors (1.2 by 1.8 metres indoors, slightly smaller outdoor run). They get on extremely well. The reason I am considering adding a third is because I don't want the 1 year old to be on her own when the older one dies. I could wait until that happens but its quite hard to find female guinea pigs for sale in this area, so it would be likely to take a few weeks to find her a new female friend. I have been offered a female baby guinea pig but am having doubts, is it likely to be a mistake to add a 3rd?
Thanks
