? Did you have a water dish available to your snakes at all times?
How large of prey did you give your snakes? Prey shouldn't be much bigger around than the largest part of the snake.
Also - did you feed frozen/thawed? If so, how long did you thaw the prey? If the food was still frozen on the inside, that might be an issue.
Did both boas come from the same place? How long after you got them did they die?
Boas shouldn't regurge and then immediately die for "no reason". Regurging is bad, but does happen from time to time, but one regurge doesn't necessarily cause death, and since it happened to you twice in a row, something about the way your setup or feeding routine might be very wrong.
