Assist feeding is a great way to get a young BP eating but after you have tried a few husbandry and feeding adjustments and the animal is visibly loosing weight. Force feeding has a high chance of regurg but with assist feeding the snake swallows it down on it's own.Y ou want to wet a prekilled hopper, gently open the snakes mouth with the head of mouse and put the head of mouse in past it's ears. Genlty put the snake back in it tub(I do it right in the tub) and let it swallow it on it's own. This usually kicks in the feeding response. i keep my hatchlings in real small hatchling tubs until they are well past 100 grams and they all eat good.
