Although winking isn’t a common cat activity, it may show your cat’s affection. Cats frequently close their eyes at once as a sign of contentment or extreme devotion. Moreover, sometimes, instead of closing both eyes, your cat will just close one of them, which is also known as a “slow wink.”

There are various explanations for felines blinking slowly. Many people think that show blinking is a fostered behavior that cats have learned from humans.  However, some people believe that felines blink slowly to show a threat.

However, most winks aren’t quite pleasant. So, if your feline winks regularly or blinks frequently with only one eye, then he may be suffering from a medical problem. There are generally three main reasons why your feline winks at you.

1. They Want to be friendly

It is commonly known that feline slowly blinks to express happiness and friendliness toward the person they’re staring at. Two or three sluggish incomplete blinks—in which the lids don’t completely close—make up the so-called “slow blinking.”

The most slowly blinking feline at kennels are the ones that get adopted quickly. A sluggish blinking usually entails both eyeballs.  However, in some situations in which a feline may choose to wink slowly.

  • Their face will probably be rather motionless if they’re leaning over one cheek, letting the other cheek perform the job.
  • Face paralysis in felines can be brought on by severe traumas and ear disorders. In that situation, a wink might be produced if one eye blinks more noticeably compared to the other.

2. They’re Having Eye Irritation

Sometimes a dusty crumb may irritate your feline’s eyes which forces them to wink.  Your feline might be winking to get rid of that irritating object. These signs will help you to know this kind of wink:

  • Quick or constant wink
  • Skin irritation or watering
  • Using a paw to scratch the eye

You must check your feline if he gets something in his eyes or call your vet before the situation gets worse. 

3. Their Eye is Wounded or Diseased

Felines are susceptible to a wide range of ocular issues, such as infectious diseases, eye damage, and severe traumas.  Their eye’s cornea is more heavily packed with nerves than their other body parts, so injuries and illnesses make it extremely painful!

Blinking or winking with one eye closed are the most typical initial symptoms that cat owners notice when their feline has eye problems.  Other signs to watch out for are:

  • Excess tears
  • White, pale, or green color discharge,
  • Eyes redness
  • Cloudiness on the cornea
  • Excessive rubbing

Bring your feline to the doctor if you observe these symptoms or if you think your feline has anything stuck in its eyeball that they’re unable to remove. The veterinarian will check the eye for injuries and suggest a method of treatment.

4. Allergies and Environmental Factors

Cats, like humans, can experience allergies. Pollen, mold, or other allergens could cause itchiness and irritation, prompting your cat to blink more frequently in an attempt to alleviate the discomfort.

5. Conjunctivitis or Pink Eye

Conjunctivitis, or pink eye, is an inflammation of the conjunctiva—a thin, transparent layer covering the front of the eye. This condition can lead to watery eyes and increased blinking, often in one eye.

If your feline frequently blinks, particularly erratically and abruptly, you must watch out for additional signs of an eye problem, such as:

  • Tears
  • Cloudy eyes
  • Scratching or rubbing one’s eyes
  • Responsiveness to light
  • Your feline is irritated
  • Your cat isn’t performing routine grooming tasks.
  • Your feline doesn’t eat properly

Since nerves regulate a cat’s capacity to wink, brain functions may potentially be the reason for irregular cat winking. Even though it’s rare, facial nerve dysfunction can prevent a cat from blinking one eye, due to which the cat may also wink.

Moreover, if you find that one eye is closing more frequently compared to the other, you must bring your feline to the doctor, particularly if the winking is irregular, flickering, or if it’s followed by secretion. If you detect a behavioral change, a decline in hunger, or weight reduction, then you must bring your feline to the clinic.

It’s positive if your feline frequently gives you a soft, controlled wink when you’re chilling out. It’s an expression of confidence and love, and you may even slowly blink in response at him to show him that you share those feelings.
