Before becoming a pet at home, cats are wild animals. In its natural state, cats hunt at night, requiring the ability to see well in dark conditions.
The ability is owned by a cat because in the back of the cat's eye there is Tapetum Lucidum. Mirror-like organs can reflect light that helps the cat to see in the dark. Tapetum Lucidum also makes the cat's eyes can burn in the dark.
But this does not mean the cat can see in the darkness. Cats still need light even though not much, about 20 percent of the light that humans need to see.
With this ability the cat can also catch mice that roam the dark night. Likewise to find cockroaches hiding in the dark, cats do not need candle light or flashlight.
that is the slacker and his skill at finding prey, the night he rested.
