Live Feeder moving to Rats? Help!

[Dracorex5]

My 7-8 year old ball python has eaten live his entire life. I have spent eneogh time and effort in to trying to kove him to prekilled, and gave up a while ago. Yes i know the risks of live feeding and i work to minimize them as much as possible. I feel that standin over him holding a mouse for a while is better than a starved snake. Please, no live to frozen advice.... Ive done everything from killing mice myself to wrapping living mice in dead mice. He isnt interested. I need a different solution to a different problem

Koda is big eneogh for rats, certainly has been for a long while. I do a dangling method as to avoid bites, hoping hed take takes because they wiggle. He slithers in fear from them. Ive recently tried a little bit of scenting, to little avail. Has anyone moved thier live feeder to a bigger prey with success? Im up to feeding him three mice a week now, and he would certainly take more. He needs big boy food, but hes so scared anf doesnt recognize it! Any ideas?
