The Bright Tapestry…

December 01, 2012



A cat's ability to see in as little as one-sixth of the light needed by humans is attributed to a layer on the back of its retina known as the tapetum lucidum or "bright tapestry". This layer gathers the light and reflects it back like a mirror to the light gathering cells of the eye, amplifying it to provide more information in less light. More information in less light equals more food if you are a leopard (Panthera pardus) in the wild.
