this issue is probably long past but i am channeling foucault at the moment so here's my 2 pence worth: power/knowledge! when applied to what counts as "art" as well as "behavioral science" in relationship to animal drawings/behavior Foucault's theory of the production of bodies of knowledge is very helpful for looking at (human-made) discursive formations of animal's bodies, eg. their ebodily functions and "psychic realities." the foucault-inspired question then being, what events/ideas have given rise to the questions about animal art, what discourses of power are working to form the human subject in relation to the animal subject, through what media are these discourses perpetuated, shifted, challenged, resisted, etc... I would also add, as I usually do when talking foucauldian analysis, is the situated practices related to these discourses---where are they taking place, what bodies are doing the action, which body-spaces are at stake in these questions. So there you go. Hopefully this is helpful if not in this case for future reference. Of course, this is only my humble opinion and I could be completely wrong; and I may not even agree to the above statements in a few days time. Do what you will with these insights. Peace!!!
