Claws!

CAUTION: Sugar Gliders have sharp claws!  It does not matter if they are running, jumping, or simply sitting on you, you will most likely get scratched.  Sugar glider claws are extremely sharp and thin, so they are more apt to get stuck in your skin than simply scratch it like a cat.  As with any type of small animals, make sure to wash your hands after (and really before) handling sugar gliders.

This is not the best picture, but it shows the tiny red marks of
devastation that can occur after handling sugar gliders.

It is important to keep your sugar gliders nails taken care of.  My sister and I use a running wheel with an insert that files their nails as they run.  Some people use human fingernail clippers to trim the nails of sugar gliders, but I would not recommend it because their fingers and claws are so tiny and it would be very easy to clip if more than you intended to.
