For those interested in a follow-up and the 'apology' of one of the individuals involved in making the video, it is here:

The URL for this page is http://www.snopes.com/photos/gruesome/crushvideo.asp


Before you go, though, I should tell you the page displays 2 photos of the woman (a nurse!!!) holding the kitten, and 2 of her laying the seemingly drugged kitten on the ground. The graphic action shots from the other site are not there, but are linked to, along with several others. I didn't open those, so if you go please open at your own risk, and note that Snopes has added a strong disturbing image advisory.
