Changes in the Eyes Provide Information About Your Cat’s Mood

Pupils, the dark openings inside your cat’s colored irises, constrict and expand as the light changes.  In dark areas, the pupils expand to allow more light into the eye.  The openings get smaller in well lit areas or bright sunlight.

Changes in the appearance of the pupils or eyes can indicate:

Pleasure

As your cat purrs on your lap, you may notice that its pupils become narrow slits.  Narrowed pupils may be a sign that your pet is happy and content, particularly when accompanied by purring.  Although purring often happens when cats are happy, some cats also purr when scared or in pain.

Aggression or Anger

Pupils also tend to get smaller and narrower when your pet is feeling aggressive.  Cats may also stare and squint if they’re feeling aggressive and squinting helps protect your cat’s eyes from injury during a fight.

Fear or Excitement

Wide eyes or pupils can be an indication that your pet is facing a scary or stimulating situation.  

Relaxation

Half-closed eyes and normal pupils mean your cat is feeling relaxed and comfortable in your company.

What Blinking Means

Have you ever noticed that your cat locks eyes with you then blinks slowly?  It’s been said that slow blinking is compared to a kiss or a smile from your cat and the way your cat shows affection.  The next time you notice the slow blink, return the sentiment with your own leisurely blink.
