Kittens are born with blue eyes. They can stay that way but, more commonly, the color will start to change as they mature and the production of the pigment melanin occurs.
Adult cats with blue eyes aren't widespread. When it does occur, this is as a result of their genetics.
The production of pigment in their iris doesn't occur, and when light reflects off the rounded surface of their eye, they look blue in color. The higher the level of refraction the cat has in their eyes, the deeper the shade of blue will appear.
Genes that limit cat coloration result in blue eyes. Pointed Cats, like Siamese, who have a lighter body and darker extremities, always have blue eyes. Cats that have the dominant white gene can sometimes, but not always, have blue eyes. White cats are also genetically more predisposed to being deaf.
Below we have listed eight beautiful blue-eyed cat breeds. Some of these breeds only ever have blue eyes. For others, blue will be just one of the possible eye colors they have.

The Balinese is a modern-day pointed cat breed that will always have deep blue eyes. The long coat of these strikingly beautiful felines came about as a result of a spontaneous genetic mutation in purebred Siamese cats. These medium-sized cats aren't just a pretty face.

Although there's no such thing as a truly hypoallergenic cat breed, because they don't have an undercoat and shed minimally, Balinese may not trigger allergic reactions in the way some cats will. Balis aren't suited to being left alone too often. They love company, and if they don't get enough attention, they can be pretty vocal in letting you know about it.

This modern and incredibly rare cat breed was accepted for registration by the TICA in 1991. Their numbers, however, remain very low and the breed standard is still in development. We had to include them on the list as their eyes are always an unusually deep shade of blue, despite not having pointed or solid white coloring.
The origins of the breed date back to 1984 when a tortoiseshell cat from a feral colony in New Mexico produced a litter with intense blue eyes like hers. They have gone on to produce litters with a variety of markings, and they have perhaps the deepest blue eyes seen in any breed of cat. The name Ojos Azules is a Spanish translation of 'Blue Eyes'.
