No they are nothing to be afraid of. Unless of course, it's a rabid raccoon. Every rabid animal is dangerous.
Take a look at the pic again of them standing up to take food.
It's advised not to feed them by hand. I do, because I know which ones I can hand food to. If it is a raccoon,
not use to taking food from a human hand, he might cut you not meaning to. He might be nervous because
you are a human and grab the food quickly and slice your hand.
The first time I fed them by hand, I wore welder gloves.
Most of them are skittish and will come not too close and keep their distance of me.
When they get use to you, become not afraid, know you are not going to hurt them, they take the food
from your hand, very slowly, very carefully, they are smart and they know their claws are sharp.
I also have pet woodpeckers and pet squirrels.
Woody, is the main woodpecker that is a wild pet. He follows me from tree to tree when I put the dog
food in the tree stands. Woody grabs the dog crumbs, and flies up the trees and hides the crumbs under
the bark of the tree. Woody is a female and when she has babies, she teaches her baby woodpeckers, to
peck, shows them how to find food behind the bark....which is usually ants and bugs of course but I imagine
the babies have gotten a crumb of dog food too. I don't know if Woody remembers where she places the
crumbs, but the trees must be full of dog crumbs by now. She's been doing it for years.
