Why do cat eyes appear to glow?
Behind the cat’s eyes there is an area called the dark pupil with its light-sensitive cell layers (the retina). There is a special layer of cells behind the retina, called the tarpetum which actually reflects back any light that hasn’t been absorbed on its way through. This layer of cells acts like a reflecting mirror and is the reason for that gold or green shine we see in the cat’s eye when a glare of light is being showered in its direction.
