INTERESTING INFORMATION ABOUT CAT EYES:
A cat’s pupils should normally be of the same size as you look directly into her eyes. A change in the size of a pupil in one eye can indicate a number of health issues. It could be mild to serious. Possible problems:
•Inflammation of the eye
•Horner’s syndrome (a neurologic disorder)
•FeLV (may cause pupillary spasms)
•Tumors
•Central nervous system injury

Cats have an inner, third eyelid, which is also called a nictitating membrane. The third eyelids help to protect the eyes from dryness and from injuries. If a cat is sick, the third eyelid might be visible. Get her to the vet immediately, especially if other symptoms are noticed.
You may occasionally see the third eyelid appear even in a healthy, happy cat. Usually this occurs if she is very sleepy or just awoke.
The third eyelid is a tiny triangle of tissue. Some people refer to it as the haw. Humans have their own version of a “haw”- it being the small pink bump at the inner corner of the eyes.

A cat’s mood and emotions are reflected in their eyes. The pupil size narrows with an angry cat but with an excited or scared cat, the eyes will be wide open with large pupils. A hungry cat’s pupils will dilate up to five times their normal size when she sees her food bowl. Half closed eyelids say that she’s totally relaxed. Obviously the eyes will be closed when she’s sleeping. When threatened or forced into submission, she’ll close her eyes and the tormentor will feel he’s won then usually walks away, leaving her alone.
~~~~~
Cats can have many of the same eye problems as humans, such as cataracts, glaucoma and pinkeye. Pinkeye in cats may be contagious to humans.

Cats’ night vision is superior but they cannot see 100% in total darkness.

Cats cannot see directly beneath their noses.

~~~~~
A cat’s vision for far away would be about 20/100. Some things up close may be fuzzy or blurred, though.
~~~~~
Most white blue-eyed cats are deaf.
~~~~~
Cats will give you “kisses” with their eyes. It happens when they stare at you and then slowly blink at you. Try doing this to them and see if they “kiss” you back. It is a huge compliment getting a kiss from your cat and she is showing how relaxed she is with you.
~~~~~
When a cat is in the dark, her pupils open wide and light reflects off them, giving the illusion her eyes are glowing.
~~~~~
Cats see the world in shades of blue and green.

Gina says: It amazes me how those pupils change in size and appearance. It’s like magic! Sometimes they resemble the shape of diamonds.
