I understand your fustration and confusion. I've had some pretty big struggles myself.

The whole live vs. f/t thing seems to come down to either violently opposed or completely fine with it. There isn't much middle ground that I've seen.

As much for convenience as anything else I started all mine on f/t. Things went well for a long time, and I was satisfied. Then I acquired an older snake who had always been fed live, he's got the scars to prove it. So after several months of attempting to change him, I decided it wasn't worth the stress to us both nor the wasted food and let him have live. Over time, I acquired other snakes, ones I had changed habits, so now I feed about half and half.

I will say, as best I can tell the majority of injuries come about from unsupervised feedings. Yes there are exceptions, but for the most part if you supervise live feedings you stand a good chance of being able to intervene and prevent injury.
That being said, I desperately wish all mine took f/t. I don't like feeding live. I know no matter how careful I am, there is always risk involved with feeding live. I also know that people who claim ALL snakes will eventually take f/t are mistaken. There are plenty of people on here who will tell you the decision to feed live over f/t was a long, drawn out battle and in some cases the snakes life depended on the switch.

I also feel your pain in this particular situation. As I said before, I've seen very similar behavior in one of mine. This female should easily be 1200 grams plus, but her continued feeding strikes and refusals have kept her at just under 900 grams for the last 6 months. And even when I asked for advise her on her specific problems, no two people told me the same thing, making it difficult to find a solution, or even help her problem.

My only suggestion to you is to give her some time to relax and recover her equilibrium, try not moving her for feeding if you can, and obviously don't offer her that same rat again. As difficult as it may be, try to move past this. I've read somewhere that snakes can pick up on our moods, so maybe if she senses you are stressed out wondering if she's going to do this again, that stresses her out ? Unfortunately I don't know how to help you out, since I'm still fighting the same problem as you, just for a lot longer, and I have no clue how to make it go away.
