I think that I have a Russian Blue purebred kitty. After looking a a bunch of sites, I am convinced that I don't, as it states that they are very closely kept between breeders and usually don't turn up at the humane society (thats where I got mine). On the other hand I have seen tons of pictures of actual russian blue's and my Duffy looks just like them. They say their fur feels a little different (like seal fur or beaver fur) and duffy's fur feels different from all the cats I have owned. I don't know what to think, it would be nice to know if I have a purebred :-D
