He doesn't look angry - but he sure it giving me a direct stare-down! I'm not sure I've ever seen (or at least noticed) the bottom of a squirrel's foot before - such a pose.
That is the squirrel shot to end all squirrel shots. Our California ones can't compete with this one. Strangely but true, the handsomest squirrels I have ever seen were on the grounds of Walt Disney Studios. They look like they were created by Disney's Animatronics Department. But I don't think they could act, pose, or emote like this guy.
I can just picture its little nose twitching as it tried to decide whether or not you were a threat. You captured your interaction perfectly! I love the squirrels...so full of personality!
