This is what I would do. Heat the pink to HOT, not warm. 102F. It just takes a minute or so. I like the pinks to be wet, not dry. The snake will often start by drinking moisture from the pink and then go on to eat it.
Have a little container- no larger than a margerine dish- the deli cup the snake came in, if you have it. It has to have tiny air holes.
Feed in the late evening, when the snake is active.
Right before you put the pink in the container, heat it by running it under your hottest tap water for a few seconds. Cut 4-5 tiny slits down its head and back- just through the skin, with a little scissors. put the pink in the feeding container.
Get the snake, with a minimum of fuss place the snake in the cup, put the lid on securely, cover him up, in a dark area, leave him strictly alone for 30-60 minutes. If he hasn't eaten after that time, reheat the pink back up to HOT and replace it in with him, cover him up, leave him for 60 minutes. If he still doesn't feed, reheat one more time, put him in his cup, with the lid on, put that back in his viv, not over the heat, and leave him overnight.
Do not handle the snake at all until he has fed for you.
