When I just fed my snake a worm, it grabbed it without hesitation, but, even in a seperate tank, got bedding on him. So after getting it off he was more hesitant to eat, but ate nevertheless (is that one word?). After he ate the struggling worm which kept crawling away, he started rubbing his head on the ground and "yawning". Then the lump in his body started moving back and forth. Was the worm trying to crawl out of his stomach?
I have heard of this happening with
big nightcrawlers, but never simple earthworms.
