00:00Why can cats see so well at night?
00:03The answer lies in the unique structure of their eyes.
00:07Cats have pupils that can open much wider than human pupils.
00:12This allows far more light to enter their eyes in dark environments.
00:16Inside the eye, cats also have more light-sensitive cells called rods.
00:22These cells help detect movement and shapes in low light.
00:26But the most special feature is a reflective layer behind the retina called the tapetum lucidum.
00:34This layer reflects incoming light back through the retina, giving the eye another chance to detect it.
00:41That's why cats' eyes often appear to glow in the dark.
