I've just uploaded a video on Youtube of my 3 girls!

They are so tame as you can see, they are more than happy to run on to your hand. I think this is because when they were young I would place them into a box and just put my hand in. If any crawled onto my hand I would replace them back into their cage! As time progressed I would handle the robo which crawled onto my hand for a short time, lengthening it the more confident they got.
And yes, I do have big hands lol!!
