we have 1 glider we can pick up.
Another one you can pick up but she MUCH perfers just to climb up your arm and onto your shoulders.
Another one we have had 7 months and he hates being held, but I do have it so he doesn't bite anymore if I do pick him up, yesterday he tried SO hard to get away and after I got him and showed him my shirt pouch with sophie in it he was more then happy to get in have some treats then sleep and groom away.
the last one I dont pick up, we have had 2 months, but the wife has gotten to pick up lately without getting bite.
