Without being too spoilery, if anyone watched episode 6 of season 6 of game of thrones, you'll know that a certain character rides off with a horse and returns with a dragon. Me and a friend were jokingly agreeing that she probably fed the horse to the dragon, but also started wondering about a dragon's metabolism.

Do you think they would be similar to monitor lizards and Burmese pythons? Only eating once a month-ish as adults, or would they need to eat on a daily basis? Thoughts?
