So I've been unsuccessful feeding like 3 weeks in a row for my two larger females, but my new little one has eaten fine. I've noticed a couple of times the snake will strike or S up like it's going to, then either after biting or checking out the rat, it'll lose interest.

I recently moved up to a larger size of prey (but they'd fed on it before and the weight ratio is fine, to the point where they were probably ready for an upgrade before this) and I've been noticing that when I heat the rats up, these larger guys seem to end up more moist at the end. Could this be what's turning off my BPs? Maybe like, since the little guy is eating rats that don't have hair yet, it feels less wet to it?

Thanks all. Starting to get a little stressed. I know it's the winter and all, but they were fine before.
