What is art???

In my art class, we've been talking about the aesthetics of art, or rather how people determine that art is art. Basically, society does to some extent, and it's a personal opinion of where to draw the line (if you draw a line anywhere). As part of this discussion we discussed the possibilities of animal art. No, not picture of animals but animals making the artwork. I was very skeptical...

And then we saw this video...

Confession: I still don't know if I call it art, but you might.

We also saw a crazy video about a man wanting to kill a rat for art. And the killing of the rat is the art. Crazy.

P.s. I also painted an abstract flower with watercolors that I am pretty dang proud of, which is a rare occasion.
