Here's the rule for feeding that I've been using. Feed one or two rodents of an appropriate size once or twice a week. Appropriate size is 25% larger in girth than the largest part of the snake. I would say this is the general guide line that most breeders use. As for Spitfire's question about using up some pinkies, that's not a problem unless you've got a couple hundred left. Then I would buy some more snakes lol.
