when I approach their pouch during daytime, they still crab a bit. I've no idea what's going on in their heads.
they dont know whats going on, what is that strange sounds outside our house, do we have a dangerous situation, are we in danger, lets crab and scare them away.
think of it like their alarm system and siren. My dogs hear something outside and
they bark, they don't always see what it is they just hear a noise and bark and go
to the front door. I feel it's the same with glider, they may never stop crabbing,
but most likely one will stop, one might keep up the alarm system always. I can easily reach them with my hand: at first I give them a couple of treats (that they enjoy very much) and then I cuddle them a little (I softly pet them with my hand).
I don't know if they're doing this (don't crab, don't bite, let me pet them, let me feed them) because they're too scared to do anything
My less bonded gliders will either move slightly away, or all the way away to
back of cage. so if they are bothered or scared I would expect them to show it, even if its by fast breathing. I would suggest to keep it slow, but sounds like
what you are doing is going well.
