PRESENTATION OUTLINE
HOW CATS SEE COMPARED TO HUMANS
BY, OLIVIA GOMEZ
The biggest difference between human vision and cat vision is in the retina. The retina is a layer of tissue at the back of the eye that contains cells called photoreceptors. The photoreceptors turn light rays into electrical signals, which are processed by nerve cells sent to the brain, and translated into the images we see
The two types of photoreceptor cells are known as rods and cones. Rods are responsible for peripheral and night vision. They detect brightness and shades of gray. Cones are responsible for day vision and color perception.

Cats have a high concentration of rod receptors and a low concentration of cone receptors. Humans have the opposite, which is why we can't see as well at night but can see colors better.
