I got 2 guinea pigs for DS just over a year ago. They were kept in a cage, inside until may when we moved to a house with a garden and have since lived in the shed.
About a week ago I went out one morning to find one of them had died. I have brought the other one inside today to have a run around in an animal pen (normally I would have put them on the grass in the pen but it's too cold) and she is going absolutely mad, chewing at the bars. Why is she doing that? Is she lonely or something? She was never the friendliest of the two and much less comfortable being held or stroked but since the other one has died she seems worse.
Any ideas?
