I don't know as I would go for scenting just yet, I mean, if the thing eats unscented its probably MUCH easier, and you don't want it to get started on wanting only scented. My hog has been good about eating but other snakes I've dealt with have gone up to 3 months without eating or more (we lost one for 6 months once, not sure if she found any rodents in the basement or what but though slightly skinny she was ok when we found her) and been just fine. Does your snake seem distracted or just not interested? Mine will sometimes try to escape her feeding container for half an hour before finally deciding that the pinkie is not just something to try to dig under, and then she eats 2 no problem. maybe try the split brain pinkie (or punctured brain, as suggested before)--if it were me I'd probably figure my snake was going to die if it didn;t eat right away before trying scenting...don't want to start bad habits that might make feeding a chore in the future. I've also had success 'assist feeding' a carpet python (she only ate every couple months and only when we pushed it into her mouth), but it's something better done by someone who knows how, and preferably 2 people, 1 to hold the snake and one to maneuver the food into the mouth.
