She went into brumation a girl and came out a boy!

I witnessed an obvious play for dominance at the food bowl this morning, that I know would have escalated into a full blown fight between my known male DI and what I thought was one of two fems. Well, mauzi, whose name will obviously have to change, is clearly a boy upon close inspection. He is now temporarily in the chuck viv. I guess he was just very young when I got him last year.
