Cat’s Eyes

Have you ever considered why the cat’s eyes shines in the dark? 
The cat’s eyes are like the human’s eyes. When there is a little light, apples of the cat’s eyes enlarge as the same as human’s and reduce in daily light. Shining in the night is considered of inner covering matters on the bottom of eyes. This reflective covering may be pink, green, blue and even gold. Depending on the incident light it reflects a different color. Thanks for this cats see in the night about seven times better than people. Some cats may have two different colours of eyes shining in the dark.

The cats may have eyes in one of the three basic shapes:
  • round 
  • inclined 
  • almand-shaped
Theirs colours are usually green, gold and rarely blue. They may occur in many different
tones.

While most cats do not distinguish colours, but his eyes are adapted to the use of trace amounts of light, which allows him to hunt at night. Also has a much wider viewing angle than a man, which allows him to perceive the slightest movement of potential prey.

Cats view the world in the colours, at least in the green and blue and their combinations. No cells are sensitive to red indicates that the cats probably do not distinguish color, but that the objects as they appear darker than green, and blue.
