Squirrel friend (Update)

I've been feeding a wild grey squirrel by hand now for 5 months, just today I got it to accept a peanut straight from my hand 3 times. Its also not afraid of me or my voice or anything. Its almost domesticated (I always wanted a pet squirrel) but I'm not going to take it out of nature, just be friends with it. I have noticed it has a very messed up mouth, I think that's why it started trusting me to feed it, perhaps another animal bit it long ago or it was born this way. I still don't know its gender but I call it 'Guy' as I have this 'feeling' its a Guy. Oh and it comes when I whistle just like a dog, and since he can't get my attention when he wants food he does this funny slow motion stalking thing right up behind me and will just stop and wait for me to notice him. He even walks into my garage when he sees me in there.
