Yep, Mike has it.
A lot of people will call the color - Siamese, because that is what they are most familiar with, but Siamese is a breed - not a color, and actually "colorpoint" is not a color either - it is a PATTERN.
The "points" come in different colors. Like Mike said, they are heat sensitive and therefore show up on the ears, and face first, then the tail and feet.
So any color a "regular" cat comes in - a colorpoint cat can be. Blue (gray) orange (red or flame point), etc. A seal point is genetically a black cat underneath.
I've never had a colorpoint kitten before so I was excited when these ones came along. If you compare the white on your pointed kittens to the white on your black kittens feet, you may be able to see a difference in the whites.
I have had fun watching this little guy grow. He is by far my most favorite kitten ever, and I will be hard pressed not to adopt him when his time is up. It doesnt help that he is so darn sociable. His litter mates like to stay hidden under the couch where are this little guy likes to curl up on me.
Anyway, if you want to see some examples, just do a google for "colorpoints" and browse through the images. There are a ton there. I had fun trying to guess what my little guys colors would come in as. At first I thought for sure he was gray/dilute. But nope.
The colorpoint gene is a recessive gene. This mean both parents have to carry a copy in order to pass it on to visibly appear on their offspring.
Now I really cant wait to see them grow!!!
