Sugar gliders make a variety of sounds to communicate including "barking," "chirping," "crabbing," and "hissing". These noises can convey everything from fear to a desire for attention.
Gliders are very territorial and will bite.
Owners should begin handling young ones as soon as they are fully weaned to help with bonding.
Sugar gliders are community-oriented animals and do best in the company of at least one other sugar glider. They will not be happy alone.
