Yep I noticed you're from Toledo too. So the vet you saw said that the reason for a regurge after that many days post-feeding was due to impending shed and was no big deal?

Far be it from me to argue with a vet but I've had a far few snakes shedding over the past couple of years and I've yet to see one regurge for any reason, but especially not due to shedding. I'm glad the snake checked out okay. Did the vet do a fecal float test on feces to rule out internal parasite load?

I'd definitely give the snake a bit of extra time before another feeding, feed lighter than normal and make sure your husbandry (temps, humidity, hides, thermal gradient, etc.) is dead on. Regurges are nothing to fool with.

After four days there shouldn't be anything much to "get rid of". What size and type of prey did you feed her that she regurged? I don't believe you ever specified that in this thread.
