Well I was switching our sugar gliders from their sleeping pouch (open topped pouch) to a zippered pouch so they could come with me during the day while I ran my errands. Well Opellio went nuts and shot off the cage and went right up a pole and into an exposed part of the ceiling. He was so fast that I couldn't catch him. Now he's in the ceiling and probably won't come out for a while. I have been told by other glider keepers that he will eventually come down but I'm still worried.
