What Breed do you think my Cats are?

This is Sasha she is Russian Blue but not sure what else.
This was Yoshi the Vet said he was Abbey
This is Coco she is part Siamese
What else can my Cats be? This is Meeko and she is part Russian Blue her Mom Is a Russian Blue but you can see Meeko didnt take the Russian Blue side. She has the same Mom as Sasha.
This is Oreo and she has Russian blue in her but is something else. She dosent look Russian Blue at all.

Sashas eyes are changing to green now.

The RB looks a little like oriental in the background (sharper features).

Yoshi and Cocoa - there is some aby or ticked tabby in the background of both. The one is a brown patched ticked tabby (the one in the back with the red patches in the coat).

Not sure about Oreo - probably domestic sh with the RB.

Remember a female can mate with more then one male, so its very possible that each have a different father

I see that is my Russian Blue too. The one with the 2 Cats is Yoshi and Meeko.
The Black and White in the small Pic is Coco.
Meeko is Yoshis Mom. He was her only Kitten but i juts lost him at age 5 from Kidney Stones. We talked to Uc Davis about a transplant too but they said he didnt qualify because the Stones would come back and there was to many. Here is a better Pic of Coco
This is Meekos and Sashas Mom You can see the Oriental in her too. I think I have a Pic of Oreos Dad. I will have to check my email. i am pretty sure i was sent the Pic of him.
