hey I knew it was a BP...
told ya guys the avatar threw me...lol
ok...crickets are def outta the question. You mite want to leave a live pink in there. A live prey item might make it eat. Maybe also leave the room...it might be nervouse to eat while a HUGE giant with feeding tongs is looking down at it

( well thats how I would feel being that smalllol)
you can also try braining the pink/fluff. When was the last time it ate? and please never force feed it!
oh yes... to get it warm...yeah you can defrost them in warm/hot water...
How do you thaw your rodents?
ball pythons like most python species have heat sensing organs on their lips...they can "see" heat. So a warm prey item might trigger a feeding response.
