I had gotten these 2 guinea pigs 2 years ago. They were a bonded pair, one they said was less than a year old and the other one was significantly older. Well she had died yesterday in front of her. Today she seems to lay where her friend died and only gets up to look around the cage for her. She doesn't come out of hiding either. She doesn't take treats from anyone now. Currently she is in this huge cage by herself and I feel bad she's alone. I have another female pig but she doesn't like her. What do I do, try to bond those 2 or get her a new friend?
