Are you positive that's what it was? How old is the snake? I just has a 70 gram yearling poop in her water bowl yesterday. She's just gotten onto large fuzzies. So the poop was mouse-flesh colored, and wormy-looking, with hair, with no urates. It took me a second to decide it was poo, not regurge. The sign was the diameter of the dropping- snake intestine-size, and ropey, not a solid lump. I wish I'd taken a photo of it.
If you're positive, I'd skip the next meal and feed a prey item half the size of the meal that was regurged, and powder with Nutribac.
