Russian Blues are different somehow...and I love that color. I used to have a cat who was part Blue and part Persian, i guess: longer coat but the same gorgeous silvery-blue-gray color.
Rotty, I dont think shes 100% Russian Blue, but she definately has some in her. Shes a shelter kitty, all our pets are adopted from shelters (we only have 2 but any pets weve had have been shelter animals)
