LMAOOOOOOOOOFF, THAT IS A TRULY EVIL SQUIRREL.

I'd be wondering if it's in the early stages of rabies coming that close to humans.

I watched it and it appears to me the squirrel seen its image reflection in the window. Doing a teritorial thing to the mirror image.

True Jap, but there are different times when the window is lifted and only the screen lies between the squirrel and the guy....
Watch at 1:06, when the guy makes a noise and the squirrel comes real close shortly thereafter and starts making noises....lol

Yes sully, he's cute though. I have a soft spot for animals, but not if it's rabid, like Konane said.

I think the guy has been feeding him (look how fat he is) but has stopped so he can make this video. Poor baby just wants some yummy food.

If you've ever had squirrels in your attic you might not be so generous. Feed them and they reproduce like rats and move in your house. They are in the rodent family which might put it into better context.

I've been chattered at by a squirrel wanting me to go away but that dude was aggressive. Something wasn't quite right with it.
