Are these kittens from the "Turkish Van"-look alike in your other thread?
Usually, when kittens are practically copies of momma, we may suspect they are purebred.
But the Van pattern is pretty strong, and its not unusual we do see a domestic barn cat momma, with van pattern, she has her whole litter van - patterned...
The little unusual here one of the kittens seems to be diluted, his spots are blue, which is diluted black.
I suppose daddy was the black-carrier...
Btw, this pattern is really Harlequin-pattern, but its very similiar to Van pattern, and some Van cats have it too...
Thank you for your input, but these kittens are a pair I found for purchase recently, and my cat from the other post was my cat of 15 years ago (old pictures I uploaded). I know Turkish vans are rare but I wanted to see other opinions because of them being so rare
