I have a sugar glider room. the cage isnt even put together completely anymore. I made a 20 gallon tote into a sleeping house. 5 of them come out at night and run the room. (made glider safe) and one female, no. 6, stays in the cage, she wont generally leave the cage. at night I can find them sleeping or hanging out in different parts of the room, running on the wheels. once the sun comes up I can find all 6 sleeping in the tote when I take out the old food and do my glider check.
