As I was saying in a thread earlier today, once a week feeding is healthy and good for any BP. If you over feed, you may end up with a faster growing snake, but the snake's body can be stressed from growing too fast, and some believe overfeeding can shorten the life span.
Snakes' digestive systems are designed to take infrequent, large meals. I reccomend feeding one rodent the size of your snake's girth once per week.
