he should have a glider safe running wheel. free runners good.
its also best to have 2 gliders or more, they are colony animals, social animals and most like to be in groups like in the wild. if its dark, outside or in the room, they think its time to wake up and eat and play. I work at night and sleep during the day. when we first got them I moved cage into bedroom to keep away from dogs, just in case, and it was 12 noon but bedroom dark, they woke up and started playing making all kinds of noise. your glider could also really like staying warm with your body heat. you could add extra fleece pieces into the pouch.
