Dante is handsome, and I'm so glad you've been able to get him inside and safe. Thank you.
I fed a big ginger outside for several years and it took me three months or more to get him to trust me. I used to feed him in the carport on the hood of the car when I had one. One day he left his food and came right over to me. I stroked his head twice and he turned away and jumped down. Then he looked up at me and I'd swear his expression said, "I can't believe I did that."
So you're quite right. Don't push things and mostly they come around.
One fun thing about big ginger was that a few times he wanted something and I didn't know what it was, so he'd turn round, and from a distance spray in my direction.
