A link sent by Toan, reminded me of Wim Delvoye. A belgian Artist who tattoos pigs alive. I have been kind of obliged to tattoo dead pig skin (by product from meat industry) as training. I did not feel too confortable about this to start! I couldn't tattoo a pig alive for sure! I don't think they deserve it! They definitely did not ask for it!
Anyway, in the name of art, here it is! Not sure what the organisations who protect animal rights have to say about this! Woud be interested in hearing the debate. If Art is really trying to make a point. Why don't the artist start by really/truelly respecting the animal.
