I'd say that open for discussion. Even taking a dump can be seen from the perspective of art, although I agree for us humans it's quite far out there.
Perhaps to smallen the gap, think of a dung beetle rolling a ball of poo.
I'm not saying you have to like it or even that it's noteworthy, but art in my opinion as definition can be anything that is created by something. As long as an observer looks at it as if it were art.
I wanted to pedantically correct you about the a / an.. but then realised you got me.
