I agree, you have to back down on the feeding. I'm hoping somehow in the cooler months you can make a seasonal change that forces her back into natural SD migratory feeding cycle.
I was reading an article on diamond pythons that discussed overfeeding, and inadequate temperature changes. Granted that species is completely different in many ways. I know the evolutional/history of the dwarf populations. They are supposed to feed less and eat smaller prey items. During the migrations, they certainly will eat more, but even still Mother Nature doesn't make it easy.
I know it solves the pushing issue for a short time, but is likely starting to add up internally. It is a very frustrating situation that I wish I could help you with.
A buddy of mine talked to Garrett for an hour yesterday and holds him in high regard. He maybe on to something in mentioning your girl could be conditioned to push and then receive food.
Too bad they don't make those embarrassing "cones of shame" that we put on dogs with licking problems, for snakes LOL!
She's driving you nuts, and that's the opposite of what we want from this hobby . Grrrrrrrr!!!
