Can sugar gliders be left alone?
A single sugar glider, kept alone and in captivity, will not do as well as a glider permitted to socialize with other gliders. Indeed, isolation can kill a sugar glider. Gliders require interaction with others. Some experts even say that sugar gliders need interaction with their own kind, as much as we humans need interaction with other humans. Gliders have complex social structures and behaviors governed by complex social mechanisms between groups of families, between family members themselves, and between individual sugar gliders. In captivity, unless you can provide a zoo-like setting, keeping sugar gliders in groups is simply not feasible. So sugar glider pairs works best. However, keep in mind that many sugar gliders thrive in captivity with only the companionship of their human owner.
