We got two guinea pigs a couple of months ago and one passed suddenly after only a month with us. We decided to wait a week or two before getting our remaining piggy, Penny, a friend. The day after Scooter passed. We saw a significant change in Penny. She seems SO much happier to be alone! She interacts with us much more, she plays more, explores more, absolutely adores our kids... Has anyone ever seen this? I honestly don't want to get her a friend now, I'm afraid it will do more harm then good. Is this an okay decision? Do piggies truly have to be in pairs? Maybe ours is just a strange cookie.
