How Long Do Kitten Eyes Stay Blue?

Kitten eyes are blue for about three months, but the coloring will fade to a pale silver in adulthood. The color of your kitten’s eyes can change at any time during his or her life, so it is important that you keep checking them frequently. It is not unusual for dark-eyed kittens to have darker eye colors as they age and their eyelids begin to close together. Changing eye colors with age may also be caused by an underlying health problem.
