At what age do kittens' eyes change color? Why do kittens' eyes change color? We tell you everything!
Most kittens are born with blue eyes!
You should know that the vast majority of kittens have blue eyes when they are born, much like human babies. When they are able to open their eyes, we can then see a blue / gray or clear tint in their iris.
It is estimated that this coloring which tends to blue is partly due to the very young age of the kitten. The poorly developed, weakly pigmented eye allows us to see through the deep layer of the iris. It is accentuated by the phenomenon of refraction of light when the latter comes into contact with the cornea.
However, the blue eye color common to most baby cats is not always definitive. Few of the kittens retain this blue coloration permanently, but certain breeds of cats are known to have blue eyes. The iris is subject to color variations during the eye development phase, in the weeks following the birth of the kitten.
How is the eye development in the kitten?
The development of the organ and the sense of sight occurs gradually in kittens. Note that the latter are born almost blind and with their eyes always closed once they leave their mother's womb. This protects their eyes, which are still very fragile and vulnerable during the childbirth process.
Thus, they see blurry when they are able toopen their eyes slightly within 2 to 16 days of birth. When they open their eyes fully in the 3rd week, their eyesight has improved slightly but not yet perfectly clear. At this stage of development, it is already possible to observe the blue tint in the kitten's iris. It is onlyat the end of the 5th week that the eye reaches its final vision.
However, eye development is not complete, it takes its course with coloring for about 6 months to 1 year, until the iris pigmentation stabilizes and the kitten's eyes achieve their final color. . The eyes of cats definitely have innumerable surprises in store for us.
What colors will the kitten's eyes become?
At the end of the development of their eyes, many kittens lose the blue pigment of the iris in favor of another color. That said, some rare breeds are predisposed to have blue eyes like the Ragdoll, the Sacred Burma or the Snowshoe. Finally, other kittens will have eyes of different colors like the Turk of Van.
