Okay just an update. On Monday I tried to feed him a frozen/thawed small mouse. I put him in his feeding tub and shut the lid. He kind of just looked at it and walked away. I was unaware of the dangling technique.

With this failure I put him back in his cage and left him alone for a few days. I tried to feed him a live mouse yesterday and he seemed much more interested. He would go up to it, get really close, then the mouse would move and he would back off. After an hour of that(with close monitoring) I took him out and left him alone.

I now have a mouse living in his feeding tub. I'm not too sure about what to do with that... I guess I'll just give it food and water...

Should I wait a week and offer again? Would it be more comfortable for him if I put the mouse in his cage? Any tips are appreciated.
