See, that's why I was confused. I thought that I was just mistaken, though I was pretty sure that I had a working knowledge of genetics..
I recently bred my queen, Trina, to a cat that I would swear is a tortie. He seems like he has a perpetual sun spot on his head--the rest of him is gray/slightly tawny due to what I believe to be red, there was just a lighter spot on his head. According to the owner of the stud, he's sired many kittens of great qualities. I suppose it could have been a very light brown, but I always thought that to be a form of red.. or am I mistaken there?
Somewhere something is strange. Hmm. It bothers me that it only just NOW struck me. Sigh.
