If you want a family pet a ferret would really be better. Sugar gliders tend to bond to one person and bonding with a glider takes a LONG time. I had a glider and she NEVER bonded with me .

Ferrets can make excellent pets but make sure that you can handle the smell. Also think about adopting an older ferret from a shelter. They really need a home and that way you don't have to deal with a nippy kit.
