Cat Eyes Shining

Most of us have seen a cat’s eyes glowing beside the road at night.  The glow is simply a reflection of a car’s headlight.  The back of a cat’s eye is lined with a special mirror-like material called “tapetum.”  This shiny layer helps the cat to see in dim light by catching even the faintest gleam of light and concentrating it on the retina.

It also reflects the light of a car’s headlights and causes the cat’s eyes to glow brightly.  The cat’s special kind of eyesight allows it to do most of its hunting at night.  A cat cannot see in complete darkness any more than we are.  – Dick Rogers
