We have a darling Russian Blue. We found our breeder by going to a cat show, talking with different breeders, and getting recommendations. We then visited the breeder who was recommended at her house, saw her cattery before we put down a deposit. I highly recommend meeting the breeder first, finding out how the kitties are raised (underfoot or in cages) etc. It is so important that the kitties are properly socialized to other cats, people, children etc -- particularly Russians who are already on the timid side. Exclusively cage raised kittens are to be avoided.
Have fun finding your new fur baby :tounge2:
