How many breeds of Siamese cats are there?

There's actually a bit of a misconception here. There isn't a "breed" of Siamese cats, but rather a colorpoint pattern within the Siamese breed.

The Siamese breed is one breed, but it comes in many different colorpoint variations.

Think of it like this:

* Breed: Siamese

* Colorpoint variations: Seal Point, Blue Point, Chocolate Point, Lilac Point, etc.

So, while there are many different colorpoint variations within the Siamese breed, there is only one Siamese breed.
