Cant Find Rat Pups

[beaglegod]

I realy wanna switch my BP over to rats,hes my only snake right now so ordering 6 bucks worth of rat pups and than spending 35-40 bucks on shipping is a bit much. However no one near me sells the pup size. Hes 2 foot and as you may have remembered from a previous post of mine, turned down a 5 inch long rat that I believe he could have gotten down since it wasnt much thicker than he is. Well that was two weeks ago,last thursday I offered a F/T mouse, he didnt bother with it.So I skipped even trying to feed him on his regular feeding day (sunday) and I will try again this coming Sunday. That will make 21 days since his last meal, any suggestions for getting him going again? Try a small rat again? Try a mouse again since thats what he was used to eating?
