Spencer-Don't want to dwell on anything really delicate, but my orange tabby (Toot) was neutered as a kitten, but when he was about 5 he persistently "mated" with some in-season fosters I had! I thought maybe he was "tetched in the head" so, even tho he's gone now, I'm glad to hear he was probably normal!

I had once made the observation that I had never known of an orange girl, did the research, and discovered a figure close to your 60%. They went on and on about how orange was not really orange, it was the absence of black - I'm pretty smart, but my eyes starting crossing by then and my quest to learn cat genetics was very short-lived!
