She's a very nice Russian Blue lookalike! She has that slender body, modified wedge-shaped head, silvery blue coat, and green eyes. It does appear that she has slate paw pads, instead of the lavender pink or mauve of a Russian Blue, so she can't be full RB. Still possible that she has some RB ancestry. You could always call her a Maltese cat, which is a blue cat of indeterminate breed, or a blue Domestic Shorthair.
Oh I see, thank you for the clarification, This is my first time having a cat like tasha, Our cat in our house are siamese breed, I don't know who is tasha's father. Her mother is like this.
Abyeb has an nice analysis, which I agree with. Abyeb even saw the color of the paws and interpreted it correctly foresawing the next pic - of the non russian momma.
Whom is sweet and nice in her own fashion but no russian.
What gorgeous eyes she has - another point to look at for rb lineage is nose profile - should be flat - here is Niki's profile (has a styalised filter to show up her coats silver tipping) View media item 419138
