Exactly what she said. I forget where I saw it, but one of the main breeders of morph hogs was interviewed in a video and he showed the host some scenting items in his freezer... a frog, toad, lizard, chicken, and I think he also noted that he had ever used tuna / salmon. You rub the prey item with the scented item to fool the hog into eating it as they natural eat frogs / lizards in the wild.
