How do cats see in the dark?

The truth is, cats do not see in the dark. They can only see in partial darkness. If a cat were to be placed in a totally dark room, it would see no better than you would. However, out in the open, even at night, is it seldom totally dark. The Moon, street-lamps, or lights from houses all help to provide some illumination at night. In poor light conditions, the cat’s eye is able to multiply the effect of the light by means of special layer of cells at the back of the retina. It is this layer, shining with a green glow, that we sometimes see if we shine a light on a cat’s eyes in the dark.
