Having never met one, much less quite that "upclose and personal," I had no clue. Glad to know that. Ya know, I did know that, too. I remember an article suggesting neutering even infertile toms to prevent spraying. Just slipped my mind. Lots of things do that.I doubt he doesn't have balls because of color-linked infertility. I'm sure he was neutered if he was owned before. Very few people are willing to live with a tomcat. As I understand it, infertile male torties are full toms in every other sense, they just "shoot blanks".
