WTF!
That is nothing more than a greyish black cat startled by a bird or a mouse or something. They do this all the time apparently. My wife recoginized it instantly. I, on the other hand, was quite perplexed.
Once she told me what it was, I agreed immediately, like I was trained to do.
Heh, I just thought the image was funny! You can almost hear the semi-hysterical “WTF was that, Dude?”
