There have been several incidents in recent years where owners were killed by their large constricting snakes. The feeding drive is so strong that even tame snakes sometimes instinctively start constricting when something triggers a predatory response. If you own a large constrictor, you should always have a second person present when handling, feeding, or cleaning the tanks of your snake (someone who can help you or at least call for help if necessary). Even experienced owners can get into trouble unexpectedly since these snakes are so strong, so this is a guideline that can save your life. More on large constrictors can be found in "
