Why are all cats born with blue eyes?

There’s something special about a cat with blue eyes. Dazzling baby blues are a fairly unusual feature in the feline world and it’s easy to see why so many people are drawn to them. Blue eyes in cats are generally caused by a lack of pigment, and all kittens are born with blue eyes because cats don’t develop eye pigmentation until they’re around six weeks old, when the production of melanin kicks in.

Some cat breeds with blue eyes (especially pointed breeds) have a recessive albinism gene, which means that they’ll always have bright blue eyes. Whereas other breeds have an extra gene which also blocks the coat colour, so these cats will not only have blue eyes but they’ll also be white in colour. Here at Purina, we’ve created a list of cat breeds with blue eyes for all you blue eyed admirers.

 Needless to say, kittens that are born with blue eyes will eventually have a different eye color when they grow older.  Solid white or mostly white cats may have green, gold, blue or copper eyes. Pointed cats may have blue eyes while the most common eye colors may range from greenish-yellow to gold. 

Also, the blue eye color has no melanocytes, green eye color has a low number of melanocytes while the orange eye color has a high concentration of melanocytes.  The higher the percentage of melanin, the deeper and more intense the eye color will be while purebred cats may have more intense colors to meet specific standards.  Thus, Tonkinese cats always have aqua-colored eyes while Bombay cats have copper-colored eyes.
