is not really force feeding is called Assist feeding which does help...if your trying to switch...they dont eat it because they notice something is different...but once they eat the first one they'll know is the same thing...all you need to do is grab them by where the neck starts and gently introduce the mouse's head in its opening from its mouth...when the head is in, leave the snake on the floor and it should honk it down...if it throws it back up then you might need to feed live...force feeding is when you push the mouse all the way down the stomach of a snake ...Assist feeding is a different technique...hope it helps
