Mine like to ride on my shoulder, but every now and then they will pretend they are a sugar glider! =P Oh and they LOVE sweatshirts, ya know the pocket in the front that you put your hands, they LOVE riding in that with their head hanging out! Mine are quite noisey when together, but nothing extermely loud. And I have lost mine, well kinda.. they seemed to ALWAYS escape their first cage and sometimes they would be out all day while I was at school(7 hours) and I'd come home and they'd be sitting in my room. So I never "lost" them, they always come back. One of them knows his name very very well and will come to it when called. And they like to rub their nose on mine, I love that!
