Maybe, but I think were still on topic, if not circling the definition of art too closely.
I should have named the thread differently, because my interest isn't really in this particular story, but in this kind of situation.
When art turns into something horrible.
Harm is entirely where I can't engage. For instance the display of human bodies in germany, I think is fascinating to look at and intriguing from the point of view of anatomy, posture, musculatory systems which are really hard to draw, no one was harmed, the people were already dead and had donated their bodies to the science. Skinning cats to me seems like unnecessarily inflicting harm on a creature. It lessens the value of the piece to me.
There was another exhibit in Spain I saw over the summer where the artist would cut her hands repeatedly over the course of many months, always in the same place (some statement on repetition and authenticity in art) and another where she chews broken glass, again I couldn't engage, I guess I get the concepts but am repulsed.
