It looks like I've located another thread that was lost a few months ago.

I've seen this phenomena occurring over the last year and thought I would post about it.
It involves those tough eaters or failure to thrive snakes. It occurred over the last couple of days which reminded me of it.
I had a failure to thrive baby which was on the brink of starvation. Just when I thought I would have to put her down she started eating and eating good. I couldn't have been more pleased. I made a point of feeding this little girl everyday. For two weeks things were going well and then it happened. She stopped eating but remained interested. A few times she would grab the earthworm but appeared unable to maneuver it to swallow it. Her weight dropped rapidly and this morning I put her down.
This is something that has repeated itself at the Ranch over the last year. It's like the snake makes one last effort to make it but something prevents that success. I'm sure this situation repeats itself in the wild many times.
