I had a russian blue male kitty, whom I had put down because (2 years ago) he was FeLV positive. I still miss him. I did manage to find a female russian blue-mix at our local shelter, almost immediately after I lost my male. Her name is Puma, but she is not as friendly as my other kitty, although I still love her. Puma has a quick temper, and will strike out at any other cat whom she feels aggrivated with, including people. Otherwise she is a beautiful lap-kitty.
Personally, I like the Russian Blue breed. They are very faithful, and loving pets.
