when we got sophie, she was friendly and sweet. She jumped on our shoulder, peed on us (marking us as her property), let us pick her up, pet her and sleep in our shirt.
When we got gus, he was friendly and sweet, loves to be on us, looking for a place to jump and run, lets us pick him up and acts like we have always been his best friend.
So the nice and friendly gliders we got seemed to be just as nice and friendly with us as with first owners, they had a good trust of humans.
Sweet pea, pigpen were shy and slighly scared with first owners, acted the same way with us.
We got link and gizmo as babies, gizmo bonded with my wife in a few months, link was the kids, they let him be, finally I started working with him, after several long months he now likes me, specially for treats, he a fat one.
