Hi I'm new to the forum. I had two feamale guinea pigs named Princess and Candy but Princesses passed away last summer. But now I just have Candy she is almost 7 years old. I was wondering if I should get another guinea pig to keep her company? She lives in a 2x4 cage or would it cause her to much stress or is it not worth introduce her to an new friend because she is too old? My piggy is blind and almost deaf.
