Korats are one of the only breeds that only come in one color: Grey. They are born with golden eyes, but change when they mature to an emrerald green. If you were to shine a spotlight on the Korat’s eyes, the reflection will be green, unlike the common red we see in pictures. What makes this breed interesting? Its history! The Korat was developed in Thailand, and was considered a good luck cat by the Thai people for a very long time. It is considered one of the oldest domestic cat breeds in the world.
