Sorry for late replies, been away from my macbook most of the weekend.
I have him in a savic hamster heaven
He's been with me now for 2 days. He is still very nervous and has stored all his food in the top house of the hamster heaven and stored a lot of the food in the tube leading up to the green house on the cage.
He has taken a few treats from my fingers, but still seems very nervous and will hide in the tubing or his nest he's made. He's also sleeping loads, so I've not really seen him out and about playing much. He explored a little bit friday evening when I got him but since then he's nested in his bed and spends most of his time there. I'm hoping he will eventually be settled in enough that he won't be so nervous.
My previous hamsters were never this timid, but I guess it'll just take time.
Edit: This is him nibbling on a carrot I gave him yesterday.
