1. Take rat pup and put it in plastic zip lock bag.
2. Leave it in fridge overnight
3. Leave it in hot tap water for 5-10 mins.
4. I have a KEURIG coffe maker machine so I turn that on and get a cup of HOT water.
5. Dunk the rat pups head in the HOT water for 20-30 seconds than feed it to my snake.
My ball python will only eat it right after it has been dunked in the HOT water otherwise hes not interested, I guess he senses the heat in the rat pup and goes right for it.
