Did you for feed or assist feed those are very different, in ten year I might have FORCE feed 2 animals, now assisting is a bit more common and I have to do so every year with a few animals.

Assisting usually does not last very long 1, 2, 3 feeding at the most and they usually get the idea.

Provide a 6 inches plastic flower pot saucer if you don't already, provide temps no higher than 86/88 on the warm side.

If you assist you want to do it with a fuzzy. Assist do not force, it's a lot less trauma, but you need to learn how to do it right.

Try the brown paper trick with a live fuzzy left with the snake overnight in the brown paper bag.

When I assist multiple times I do it after a failure and if necessary but I always try to get them to eat on their own first each week, and if it fails and it is necessary I assist the following day.
