"Wing Clipping" in sugar gliders is reference to cutting the
patagium so that it cannot form a wing to fly thus making it harder for the animal to flee from human control. It may very well be myth, but it has even recently been said that some owners have "clipped" their pet sugar glider wings.
Clipping the patagium is not a valid thing to do and will only result in an animal living in pain and being extra afraid of human contact.
DONT DO IT!
