Seeing

Cat is able to see in the night six times better then a human. Their range of seeing is definitely higher then human one and is equal to 285 degrees, comparing to 210 degrees in human eye. Cats are able to see very sharp even in poor light, but on the other side humans can see more details in high sun light comparing to cats. Very interesting fact is the way that cat’s eye captures movement. It’s very sensible and if we connect that to very reliable distance estimation we have a perfect haunting machine. During night when cat is haunting it see’s everything in black and white. In fact cats don’t need to see colors as they focus on contours.

Hearing

Cat ear is moved by thirteen muscles and is very sensible for sound, especially for high tones. Cats are able to hear the sounds with frequency up to 60 kHZ . Let’s compare this amount to 20 kHz which is cached up with human ear. Cat is not only able to hear more sounds but perfectly localize the source of the sound.

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.
