I was given a five-year-old guinea pig. Her name was Bella. For about three years after I got her she lived by herself in a store bought a cage, this was before I researched about guinea pig care. When I realized Bella shouldn't be alone, I bought a midwest guinea pig habitat and I went out and got Cleo. Bella and Cleo got along instantly, probably because Bella had been so lonely and Cleo was only a baby. I was so happy with them that I decided on getting Nugget a few weeks later after building a C&C cage. Nugget never had the connection like Bella and Cleo did but they all got along very well. However about a week and a half ago, Bella died in her sleep. She was nine years old. I thought because Cleo and Nugget are around the same age, about a year now, that they would be okay because they had each other. But I've noticed that Cleo is being very reserved and isn't talking to me at all. She's always hiding in her castle and I don't see her come out unless I come with greens. Nugget, on the other hand, seems totally normal. She's out and about, wheeking and talking to me. I can't tell if Cleo is eating and drinking or not because Nugget is always eating and drinking and I never see Cleo out. But I still have to fill hay racks and food bowls daily. I'm worried about Cleo and looking for advice. Should I look at getting another guinea pig? Or do I need to give Cleo more time?
