i too have a snake with no tongue. i have to force feed her once a week, i agree it stresses the animal out but i have no other choice as she refuses to eat by herself, i have offered her live and thawed but she isnt interested so its up to me to keep her going. I brought her from a reputable pet shop whom taught me how to feed her and wouldnt let me take her home until they were sure i had it right. As far as i can tell the story of how she lost her tongue was that someone in a different pet shop (before the one i brought her from) put a live rat in and walked away, then when the shop went under she was sold to where i got her from without them even knowing that her tongue had been bitten out, it took the new shop about a week to relise that her tongue was missing, she was offered to us for a very reduced price. I will admit it is a very dawnting task each week and i hate to see her distressed, but i refuse to let her die so force feed her it is. i think its great that your snake is eating on its own again

congrats
