My guinea pig Cinnamon is 7 years old. Recently he's been pushing his igloo to the edge of the cage and sleeping with his face in the corner. He's never done this before recently, it started up this month. Besides that he's still eating and drinking as usual. He leaves his igloo to get food and water. He seems okay and healthy, but I don't know, I'm kind of concerned? Especially because he's getting up there in years. It could just be that he slept there one day and decided he liked the location, who knows.
