All the regurges I've had in my collection have all been due to just a few factors:
1. Prey item was too Large
2. Ambient Heat/UTH Hot spot Temps were incorrect
3. Food item was gross (refrozen/tumor riddled) or had not been properly thawed (ice core)
4. Snake was startled/panicked within 24 hours of eating (longer if large meal)
Regurges can aspirate fluid in the lung and burn their throat. Pay special attention for any breathing difficulties or possible respiratory infections for a while. I wouldn't offer food for at least a week after a regurge, but, I wouldn't blink an eye if the snake skipped food for a month. I would also offer a prey item on the smaller side in case there is still inflammation.
Best of Luck![]()
