Goodboy Royce is probably not a Russian Blue. His mother was a black feral cat that kept coming to our house. We eventually took her in and before we could get her fixed she rewarded us with 4 kittens (everyone in the family is now fixed). Of the four, 3 black and 1 grey (Goodboy Royce). Pretty sure we have seen his father, a rather large grey cat that was fairly battle scarred but haven't seen him recently. Even though GBR is grey with a rather short dense coat he has yellow eyes not green and he has a bit of black banding on his tail if you look closely. I believe in our history with critters we have had one "prue bred" and that was a yellow Lab, Emma. The rest of our critters have either sought us out or have come from adoptions. Prue breds or mutts and just cats, they all love you just the same.
