Thai History history
This breed is overly common and it is not widely recognized as a distinct breed. In a lot of registries they are registered as Siamese, however, there are many people who own Thai's that do not register them. For these reasons, exact numbers may not be known. Similarly, some Thai's may be advertised that have not maintained the pure lines.
As one of the oldest breeds of domestic cats, the Thai maintains the look of the ancient Siamese, much as it was when it was first introduced from Siam centuries ago. The Thai is a descendant of this original breed.
