The cats are common pet animals found commonly in many houses. An important fact about the cat is that cats have night vision and they can see clearly in dim light and in darkness. This is due to the fact that the cat’s eye has special adaptations and with these adaptations they can see through the dark. The adaptations are seen in the retina and pupil of the eye. The concentration of the rods of the cat is higher in the fovea region and so, cats see during night.
Than the complete darkness, the cat’s night vision is clear in dim light because rods are sensitive to dim light. Since they have night vision, mostly many cats are active during the night and they search food and do useful works during night.
