I was more responding to the final line of what you quoted:
I suppose her taxidermist skills may be admired, though considering that the mouse corpses on the fingers are fresh enough to leave blood, maybe her art doesn't look so hot anymore after a few months.
Still, I only would've found this remarkable if they were highly convincing fakes. Then you're doing a mindfuck and pissing off people who end up being pissed off for nothing. When you're using actual animal parts of animals that were killed for the art, it becomes too obvious that you're shooting for publicity by angering people.
