Significant Form (?)

Many of the authors we've studied so far have either hinted at or blatantly declared that the aesthetic theory depends strongly on something called "significant form" or "form." I recently brought up the question of "whether or not animals can understand aesthetic theory" in a post. This is of course, debatable, most specifically depending on the definition used for "form." Most aesthetic authors regard form or significant form as combinations of non-representational lines and colors that evoke our aesthetic emotions. Surely, an animal with proper vision can determine colors and distinguish lines in a probably non-representational way. Do you think animals can comprehend significant form, and therefore, aesthetic emotion? Would an animal be a proper, unbiased critic? Although they are experienced creatures, their experiences may not be tainted with false communications and complex outcomes as ours are.
