It is advised to offer the food animal with a pair of tongs and to feed your snake outside the residence. This ensures that your hand is not associated with food and prevents you from taking a snake at your hand during feeding. If you go for live food, you must supervise it during feeding. this is because when two snakes grab the same prey, they can injure each other and sometimes even eat each other. The ideal prey is about as wide as the widest part of the snake.
