YOUTUBE --- IZZY SILVER.
watch her videos. sleeping pouch next to her on couch. a little pee on the hand trick. some cool tips and treats. other good poster out there too.
But like the other posters said, SCENT is very important. hang sweaty tie shirt on cage.
I also think you need to do what I call a small PUSH. like with the mealworms in hand, you made them do something extra for it. I would make link go a little farther every few days to get that mealworm until finally he was not running away from me, but walking right onto my arm willingly, cause he can get a mealie.
whatever that push is, you need to make the gliders go a little out of their comfort zone and let them see nothing bad happens.
AND finally bonding can take a long time with some gliders, be persistant and a little pushy.
