If you notice that your cat’s eyes are thin, it could be a sign of dehydration. Dehydration can occur for many reasons, including not drinking enough water, vomiting, or diarrhea.

What Does It Mean When Cats’ Eyes are Slits

Cats have vertical slit pupils that open and close, unlike the round pupils of dogs and humans. A cat’s pupils can open as wide as 1.8 centimeters (0.71 in) in low light conditions, but narrow to just 0.04 centimeters (0.016 in) in bright sunlight.

The diameter of the pupil constricts and dilates depending on the level of light, with a maximum dilation of 30%.

In dim lighting, both the size of the pupil and the amount of reflected light off the tapetum increase the amount of light available to hit the retina for vision.


When a cat’s eyes are thin, it means they are not getting enough nutrients. This can be caused by a number of things, including poor diet, dehydration, or illness.

If you notice your cat’s eyes are thin, take them to the vet for an examination and blood work to rule out any underlying health problems.
