I've only had this guy (adult male BP, 2 yrs old) a little over a week, and he ate last thursday (3 days ago, went very well). I got a small rat from the pet store, but I don't have a scale so I don't know it's exact weight.

I also have a smaller BP here, who whenever he comes out of his hide during the day, is ready to eat (large mice). The adult BP is acting just like the smaller one does when he's hungry. I don't intend to feed him again until thursday (I think it's way too early in our relationship to start experimenting ), but I'm wondering if I should maybe go with a medium rat.
