How can you tell if your cat is feeling feverish? Find out next.

If you notice any type of injury or abnormality with your cat's eyes, take him or her to the vet immediately to get it checked out.Ĭats run hotter than humans, but that doesn't mean that they can't get fevers. One of the ways cats announce that they don't feel well is when their third eyelids are up - that is, they've moved partially across the eyeball. There are a variety of reasons your cat may have pupils that have different sizes. Anisocoria, in and of itself, is not a disease but rather a symptom of an underlying condition. Again, it's something you rarely notice unless there's a problem. Anisocoria, while a mouthful, is the medical term for when the pupils are two different sizes. Also, squinting behavior and bloodshot eyes are indicators of pain in cats. Pain in the eyes themselves is usually accompanied by the constricting of a cats pupils, while pain elsewhere in the body can be accompanied by dilated pupils. In cats, the pupil is an elliptically-shaped opening in the middle of the iris that allows light to pass through the eye to the retina. The third eyelid, or nictitating membrane, appears when your cat blinks or closes his eyes this wonderful adaptation moves from the inside corner of the eye to cover the front surface of the eyeball. Pain also can be indicated either by a constricting or dilating of your cats pupils. You usually don't notice the conjunctiva unless it swells up, in which case it may protrude from under the eyelid, giving the eye a 'meaty' appearance. Yellow or 'bloodshot' sclera, ulcers or splotches of color, and signs of damage (like scrapes or bruises) are indicators of trouble.Ĭonjunctiva is the pink, fleshy stuff under the eyelids that helps hold the eye in place. Obviously, this should be white (perhaps with some small blood vessels visible). You may have often wondered why your cats eyes are mostly a straight vertical line during the day, then expand at night. They may stalk, chase and ambush a targeted intruder while displaying offensive body postures, including hissing, swatting and growling. The 'white' of the eye is officially known as the sclera. Cats mark their turf by patrolling, chin rubbing and urine spraying. Old cats' irises may degenerate and take on dark, freckle-like spots, but this isn’t always a sign of trouble. It's not unusual for the iris to change with age. If you notice changes in your cat's iris or the appearance of splotches of other colors, contact your vet. Occasionally, a cat will be 'odd-eyed' each eye is a different color.

Cats usually have some variety of green, yellow or blue eyes.
