Well, since you mentioned it:
If a sugar glider is not tame when acquired, time, patience, and gentle frequent training sessions will eventually allow bonding of the glider to its owner. Gliders adore being near their owners, inside a shirt (hint wear two shirts and let the glider hang out between them, or else their claws will tickle or scratch!) or in a pocket. They will be lovely companions, who view you as an equal. Sugar gliders do not respond at all to punishment or domination, so treat them with respect, gentleness and understanding, and you will be rewarded with a devoted companion!
