I never really got the "it happens in the wild so it must be okay" argument. Don't forget many snakes die in the wild too
I agree, switch to newspaper to prevent silly things happening. Monitor her closely without stressing her out. I wouldn't be feeding her for a little while. If she starts to like she's getting sick, take her to the vet right away please =)
Actually they all die in the wild.
If the peices are as small or smaller than the feces your snake passes then it will be fine. If they are bigger then you may have an issue. Usually if they are big enough to cause a problem they will get knocked off the prey before they get swallowed.
"It happens in the wild" comments are a bit flippent. My apologies. Was not suggesting they chow down happly on branches and logs, just that feeds sometimes would not be as clean as the ones we provide in our realistic natural enclosures with newpaper substrates.
Oh btw I do have one snake who's previous owner used substrate and so I have found it easy to keep it like that for now. However I cover it with a few sheets of newspaper at feeding time and my snake knows what that means. She will pop her head out from her hide or become very alert if out.
