Cat senses – Vision

In full light, a cat’s vision is inferior to a human’s. Although they can see the whole color spectrum (unlike dogs, which cannot distinguish between red and green), they can distinguish only the most intense colors. Subtle color shading is undetectable to cats. Cats also have a lower density of cones on the retina, so their detail vision is poorer. The cone density is like the megapixels of a digital camera; cat eyes have fewer “megapixels” than human eyes.

These deficiencies are more than made up for by the special vision adaptations cats have. Like humans, they have binocular vision, giving them good depth perception over about 140°, but their field of vision is about 10% wider (200° compared to 180° in humans) In other words, they have better peripheral vision than humans. Cats’ retinas a shiny structure called the tapetum lucidum, which gives them incredible night vision; cats can see well with estimated five to seven times less light than humans need. Cats make up for their limited detail vision with excellent motion perception. I have often observed my cats have trouble finding a toy until I move it; then they can see it instantly.
