This video has been up there a long time. It was thoroughly discussed, at length, here. Her hay had just been taken away and she was mad at that. What the video doens't show is that it was given back to her and she stopped her hissy-fit. What Kay and Paul do with this horse has raised, literally, hundreds of thousands of dollars for kid-related charities. Thumb was on a whirlwind "tour" in 2007 as part of her fund-raising. She's at home now, as she was before, being treated like a princess. Trust me, she lives better than many humans do.
I'm sure there was no intent as part of this post to "start" anything. I'm just hoping to set the record straight before it gets out of hand.
