Wilma has been eating small/medium adult mice for quite a while now, but before I started breeding her, I bumped her up to large adult mice. I've been weighing her every week, and the first week on the large mice, she gained 10 grams. Now, from last week to this week, she's gained 32! She's looking kind of stockier, too, although I don't feel any eggs.
One of the things I'm looking forward to about this breeding is that both Wilma and Callisto are very sweet snakes, so I'm hoping their babies will have their wonderful temperament.
Here are some not-so-good pictures of her:
