Patience young padawan.

Firstly, your glider need to get used to the new environment (your house). Normally it'll take a week or so for joey, but yours is a matured glider (i assume?), so may be longer. Also I think it did came out, just that you never notice lol. Mine won't come out if there's light on, she likes the darkness hehe.

Once she got used to the environment, feeling less scared & stressed, she'll come out when she's comfortable. Mine absolutely love the dried yogurt drops, to the point that just by hearing the sound of me opening the yogurt drop container, she'll pop her head out to see if there's really any yogurt drop waiting for her or not. You can buy those yogurt drops from most pet shops.

Then you can start keeping her in a bonding pouch with you during the day time. They're nocturnal so daytime it'll be sleeping, so if you're bringing it around in a bonding pouch, try to avoid noisy places. This bonding period varies from 1 glider to another, some people need more than a year to be bonded with their glider. So be patience, give it time to grow into you.

BTW they're not like hamsters that will be roaming around the cage most of the time. They're usually asleep throughout the day & only comes out active for several hours at night. Unless you've really trained yours to be awake during the day & be less afraid of the light.

It's not really biting, if it really bites....your mom hands would be bleeding pretty badly already.

But yes it's annoying whenever my glider does that.
