Is it true that an animals eyes change colour before it attacks?
I believe the pupils will enlarge making it seem like the eyes change color. But they really just become more black. Everyone always thought that David Bowie had one brown eye and one green eye, but later in his career he acknowledged that he has a abnormality in his eyes so that one pupil is always dilated. Both of his eyes are green, but because one of his eyes has a much larger pupil, less of the iris is shown and it looks darker. Other people think it is a completely different (darker) color.
