Normally a cause can be found for a regurge. In this case it was probably the food change that upset the animal. Relax, as long as the animal is not exhibiting any other symptoms of illness it is probably fine.
So if it's a food change, wouldn't it be a good chance this could happen again (going back to a small mouse and then trying a rat pup again)? No signs of illness but also hard tell since he's been in his hide when the times I've seen him.
