Cats can’t see in pitch blackness, but they have much better vision than people in semidarkness because:
- Their eyes are extremely large in relation to the size of their heads.
- They have proportionally far more light-sensitive rods in their eyes than humans do.
- Their pupils dilate to let in more light.
- The have a reflective surface behind their retinas called the tapetum lucidum that enables them to better use any available light.
All of these features give the cat superior night vision.
