What kind of cats are they? They're impressively elegant! :)
They are part blue Abyssinian and part Siamese which officially makes the Occicats. However Shinji is more Abyssinian in his look and nature and Kenji his brother is more Siamese. Interesting pair to have around.
Aha. I originally looked at their colour, and at the name of your blog, and Googled "Russian Blue". Very quickly realized that's not it.I was looking for information about Abyssinian cats and found this great video. Those kittens! Aw, man, those kittens! ^^
