Phil, I've seen that picture before but never thought of their similarity until now. I think yours is more attractive because of the color contrast. Interestingly, I noticed that we both have a disctracting branch right there.
When I saw this image of a squirrel at home in its tree, I immediately thought of my encounter with a leopard in Zambia earlier this year. Seehttp://www.pbase.com/pnd1/image/55194252 I know you had already seen my image when you made this one. Did the similarity cross your mind? The two are very similar in concept -- both animals gaze at the viewer from the safety of its wooded home, and you just know what they both thinking: stay, or run?
