Strange issue, well I've got two of the infamous Bob garters, and the female is refusing the baby mice, it turns out it was the smaller male that was going after them. I even tried to force feed the female (I've done it with a picky brazilian before), but she wasn't having any of it! The female will eat fish without a problem. I don't want to feel like I'm jumping the gun here, but it seems that she's gotten a little thicker around the mid section. Could she be refusing larger meals because she's prego?
