Ok, that makes more sense.I would definitely up him to a small rat, rather than just a pup, weekly. And a scale really is the best, cheapest tool you can have to know when to worry about your BP. Just weight him once a month or so and write it down, as well as use it to check his prey size.
Also, check out this great thread if you are interested in getting him on F/T rats, so you can buy in bulk (F/T is much cheaper than live, IMO): http://ball-pythons.net/forums/showt...t-feeder-types
