The milky mug happened to be next to me and i was worried he'd fall out of his cage. No risk of injury at that low height but i don't want to let him loose in the hamster room to begin with. The hall is more suitable once he let's me know that he wants out.
Next step would be to let him walk into a taxi and place him on my lap briefly while i sit in the hall. It depends on the hamster when this happens and i gage it by their body language and behaviour.
I've never been one to place my hand in their cage with a treat on it because i see their home as their territory and don't want them to connect my hand with treats or food only. My hand is what it is, a way to get out of the cage, get stroked by, picked up with and get checked over by. I do sometimes give them a treat through the bars but their focus then is on the treat not my hand. I make an exception for Robos because they are a bit different to handle i think.
Maybe that doesn't make sense regarding taming and i'm waffling but we all have slightly different ideas and approaches.
