1. Cats, like dogs, do not see all colors as well as humans.

Cats have fewer cones in their eyes so they see fewer colors. Blue and yellow colors are seen better than greens and reds that end up looking more like grey tones.

2. Cats have better peripheral vision than humans

Cats can see 200 degrees where humans see 180 degrees.

3. Cats have an area of the retina called the tapetum lucidum

The tapetum lucidum reflects light and causes the glowing effect to the eyes when a light is shined on them. This allows for better night/low light vision.

4. Cats see best at a distance of 2 to 3 feet.

No wonder your cat isn’t that great at reading bedtime stories!

5. Cats can detect rapid motion better than people.

This is a major advantage when stalking and chasing prey.

6. Cataracts in cats are most commonly caused by inflammation in the eye called uveitis.

Uveitis can have a variety of causes. Unlike dogs, diabetes mellitus rarely causes cataracts in cats.

7. Cats also have a third eyelid like dogs.

This tissue produces tears and keeps the eye moist and protected. In senior cats, various types of cancer can develop on the third eyelid.

8. The iris color can change in cats as a result of inflammation.

Causes of this inflammation can include cancer, fungal infections, bacterial infections, and viral infections most commonly.

9. Cats respond positively to a slow blink.

If humans slow blink at a cat, they often repeat the blink. Studies have indicated this is a positive communication between cats and people.

10. Cats can go blind as a result of high blood pressure.

Uncontrolled high blood pressure can cause the retinas to detach. High blood pressure is common in cats with kidney disease.
