Very very weird regurg situation...

[WhompingWillow]

This may be an obvious question, but did you see which end the regurg came out of? I ask because I once saw one of my BP's acting exactly as you described - flailing around, opening her mouth, looking generally very distressed - and it ended up being before a huge poop. I haven't looked up photos of regurg, so I'm not sure whether that actually is or if it's just undigested fur that was passed through the bowels.

Glad she's seeming to be better now, though!
