Her Mom is part Russian Blue. Oreos Grandma is a Russian Blue and is my Sasha Mom. Oreo didnt get the Russian Blue look at all. I got them both from the same place. It was a 2 Hour drive to get them.
I am looking for a Picture of Oreos Dad. I do not know what he is but his face is weird shaped. There were 4 Kittens in Oreos litter. Two have long fur and the faces are dufferant shaped. I didnt get to see the black kitten because she was already given away.
I don't know if the standard is the same in the US, but over here there is nothing rounded on a Russian their faces are all straight lines and angles. So going by the Russians I know, yours doesn't look like one, sorry
IMO Shadow does not look RB either but as Goldenkitty said maybe she is European Lines. But considering she does not have papers I am guessing she is not RB at all. Shadow is just a domestic shorthair as is Oreo.
Like the others said, being a mix up he is a moggie (domestic shorthair if you want to be courtesy), with not much of russian blue, save the big ears. Compare with the grandmother! (yes, she is of european type, even a good scandinavian type)
However, I want to mention russian blue mix-ups are quite often black, sometimes with some white spot. Probably because the blue-grey color in them is a dilute black. Thus it doesnt need much to reinforce - is my theory.
So I can accept he has some russian background in her.
I did show her to a retired Russian Blue Breeder last week and she agrees Euopean. She told me to get a Russian Blue instead of a Sphinx. I will look at a few differant Breeds.
