My thoughts are that there is some scent on your hands that is getting your
glider to bite you and NOT your wife. I'm thinking this because he is not
biting your wife. the only other thought is maybe its the way you are handling
your glider, sticking your fingers in front of his face maybe, and maybe your
wife isn't handling him this way.
It also takes awhile for a glider to get bonded to humans, some of them
a very long time, months. you say you have only had them days.
We have had gliders for about 4 years, up to 15 of them, now at 11 and soon
downsizing to 1 colony of 6...hopefully. That seems to be the number we can
really handle and give them attention. So I'm not a long time guru but my
thoughts on biting.
I don't let my gliders bite me if possible, I don't take the bite. If I have
a newer glider I can't handle I use fleece on my hands. Our colony of 6 we have one
that is not bonded to us 100% and she may get upset and give me a tiny nip if I bug her in sleeping pouch. It's a doesn't even hurt nip. the other 5 either don't
bite or a couple may give a small nip if I really start to overhandle/ bug them.
I say don't take the bite because of the main reasons they bite.
1. in sleeping pouch, you invade their home, scare them and they bite in
defensive. this glider needs more bonding time to trust you, not for you to take
a painful bite...my belief.
2. My feet and toes smell like a tasty treat, so I now wear socks in the glider
room, they smell my toe and take a test bite, I move them away, I don't let them
keep tasting my toe.
3. A new glider is scared of their human, doesn't trust him or being picked up,
probably for fear of being eaten (similar to the pouch bite) so in defensive of
being picked up and eaten they bite to escape....bond with this glider so he can
trust you and not need to defend themselves. A book I read said anything smaller
then then a glider (in a gliders mind) is food, anything larger then a glider is
a predator. You need to take away this natural fear that your a predator.
taking the bite may work, I have never used it, and not taking the bite has
worked on all 15 gliders we have had. Pinkie came to us a white glider with red
eyes, he lunged and crabbed and acted like he was going to take my finger OFF, very fierce and angry. I still can't pick him up, but I hand feed him, he sits on my hand, sometimes walks on me, I pet him all over with 3 finger almost cupping him.
as long as I don't pick him up he is fine, doesn't even try to bite, but freaks and runs if I start to lift up, he just needs more work more bonding time.
