Through animals eyes, how do they see the world?
Has there ever been a test to see what animals see? Do they see in color? Is their vision like humans? Do animals cry? These are questions I have always seeked an answer. If animals only see in black and white, then why do bulls hate the color red? Question: in their eyes, do animals see the world as humans? Please give a reference.
