Looks like and antelope ground squirrel. Awesome pose, love it. Perhaps a crop from the bottom removing some of the stump would focus more attention on the subject (depending on whether you have done any cropping already). Nice one!
Fun image. For kicks I'd duplicate this one, flip horizontal, and combine the two reaching out to each other (of course labeled as a digital creation :))

Gotta love that shot! A tight crop might make it stronger as a "stand alone" image, but for room to put in a cute phrase, etc., I sure like it as presented. That room also shows that he isn't "reaching" for something, but is, in fact, waving to his adoring fans far below... I sure enjoyed seeing this one; thanks for sharing.
