Hi, Tycos_mom, I have no plans to change his name now,just seems really strange calling him a boy but suppose will get used to it though. I wasnt really bothered about the sex but decided to have it done seen as we were going to the vets, its nice to find out though. Looking at the markings and size it makes me wonder if my other grey is a female. He hasnt been tested and we have always called him Charlie boy which he now calls himself! lol:)
