All kittens are born with blue eyes, however the kittens usually change eye color after they become six weeks old. The reason for that is because that’s when they can develop the melanin which determines their eye color.
What’s most interesting is that blue-eyed cats actually have clear eyes, but the reflection of light causes them to appear with a blue color.
There are some cat breeds with blue eyes which are not completely black but they can have a dark coat color such as black smoke color or pointed with dark coloration.
The Siamese cat breed is probably the most popular breed of cat in the world. These cats are famous for their beautiful blue eyes and their creamy body colors with dark pointed markings on their head, paws, and tail.
The Ojos Azules Cat breed is a newer cat breed that originated in New Mexico. This cat breed is characteristic for its amazing deep blue eyes, and it is believed that this trait is inherited from a female stray Tortoiseshell cat.
