Use your right hand for now. When you need to catch your glider, do what I call an interception. It will make the glider walk on your hand. When it gets there be sure to give it a treat. The Key thing with this is DON'T try to hold the glider, let IT hold you.
Many people have different interpretations of holding their glider.
I have found that many of them actually mean they have their hands open and the glider is sitting in their hands. Very FEW gliders like to be confined. They are very independent. Providing you have given them ample enough time to get used to their pouch, when you need to get them back into the cage , you can take their pouch and hang it somewhere that they may feel safe. They will crawl into in then take the pouch and hang it in the cage.
