Actually, I could have known this myself if I'd bothered to look at any of the reference materials (IE Modern Primitives) I have lying around, but to be honest, I kind of assumed that they'd wiped away the blood for the pictures but that it woulnd't be unreasonable for them to bleed a bit.
(Besides which, I kind of figured on folks not quite 'getting it' that the hooks were going through the cat-guy's skin unless i had a little blood in the pic.)
Anyway, a kind reader sent me this picture:
of a meathook performance at the DNA Lounge in San Fran, the one my ex was telling me about. (And of course, now my current BF pipes up, "Oh, I think I've seen that.")

Hey, here's a closeup of the man's back, getting the hooks.. in? out? Probably out. http://www.dnalounge.com/gallery/2005/0
Skin is remarkably strong, isn't it?
There are lots of other fun pictures. I'm sure you can find them on your own.
