Assist feeding like that is, in my opinion, only for bp's and the like. With most colubrids I have always read and seen that it is more effective to "tease feed". (BHB has a video that states that, as well as my readings on cornsnakes.com) You take the snake and hold about a third of the way down it's body from the head, then tap it's side with a frozen thawed pinky to aggitate it. Then they will bite it, cause that's what snakes do. Lol. Then if you hold real still they are supposed to get the idea and actually eat it. Now, I've never had to do that, or felt that it was neccesary, so take this info at face value.

Also, a woman from said website, found out that if you boil frozen thawed pinkies, corns usually will go for it. Also, scenting is a good idea, and one that works is washing the pinky in Ivory dish soap. Obviously clean off the soap. I would do any of those things in a deli cup of some sort. I have a butter motley who is just too distracted to eat from my hand, so he always goes into a cup, so he can focus. Lol
