Thanks muddoc (and all of you others as well of course) for some great advice.

Would you say that one of the snakes was going in to shed would be a contributing factor for it to regurge?

I thought regurging snakes was kind of rare, if cared for properly, but you make it sound semi-common, clarification on this part please?

The food items was in their system for 15-20 hours maxmimum, also possible that they regurged it alot earlier. I offered at night and then left them alone until the afternoon the following day, so I can't say for sure. Is it likely that they will do this again?

Thanks
