At birth, a kitten’s eyes are closed.  This is mother natures way of protecting them because a lot of development is still taking place.  Most kittens tend to open their eyes when they’re 10 to 14 days old.  They look blue at first because the kitten’s body hasn’t begun to produce melanin, the color pigment that determines eye color.  Things look fuzzy to a two week old kitten but as it’s eyes continue to develop, it’s eyesight dramatically improves.  At two to three months of age, it’s eyes begin to change color. This is also the age that they become very active and love playing with their toys.  Most felines have eyes that are green, gold or copper. Some breeds such as  Siamese, Birman, Balinese and Rag dolls retain their blue eyes into adulthood.
