While I’m on the subject of the intriguing reflective and refractive properties of cat eyes, let me offer two more examples of how, very much unlike most species, felines offer a myriad of colors and intensities when it comes to light bouncing around inside their eyes.  In this case, let’s look at two photographs of Kazon.  In both cases, I used the flash on the camera.  Also in both cases, the direction he was facing and the direction I was aiming were both different.  You can see those variations caused disparate results.
