1. Tapetum Lucidum: This is a layer of tissue behind the retina that reflects light back through the retina, increasing the amount of light that reaches the photoreceptor cells. This is like having a built-in mirror in the back of their eyes!
2. Large Pupils: Cats' pupils can dilate (expand) much wider than human pupils, allowing more light to enter the eye. This is why they have those big, mesmerizing eyes in the dark.
3. Sensitive Retina: Cats have a higher concentration of rod cells in their retinas compared to humans. Rod cells are specialized for detecting low levels of light.
Together, these features give cats exceptional night vision. They can see in conditions that are 6-8 times darker than what humans can see. This helps them hunt at night and navigate in dim environments.
Important Note: While cats have great night vision, they don't see in complete darkness. They still need some light to see, even if it's very faint.
