How large should their cage be?
The bigger the better. As big as it can possibly be without making it impractical to clean and maintain. Provide a cage that is at least two feet wide and three feet high per glider. Common cage dimensions are 24″ x 24″ x 26″. When considering space, keep in mind that the sugar glider is capable of gliding 150 feet – much further than the length of most people’s backyards. Ideally, you will permit your glider ample play time outside of his cage to compensate for his relatively small living quarters. Supervised play time to romp around your home and explore the safe environment will enable the glider to be as happy and healthy as any glider kept in captivity.
