I agree move the snake to paper towels while healing...sounds like you did fine. Whenever you feed live just check to see where the head is. We have had to put our tongs in the mouses mouth at times. Not harshly ...just gently to keep the mouse from biting the snake. We do not try to harm the mouse anymore than what the snake is doing on its own.
In the future you can order Clorohexadine (sp?) from Reptile Basics....it is awesome to use for cleaning your bins. You can also use this for cleaning any bites or boo boo's that any of your reptiles or dogs/cats etc. may get. This is often given by vets for cleaning wounds...you just dillute it with water.
