..well, I'm going to feed my baby for the first time.

If it is feeding live, I recommend taking out everything in its cage, such as plants and decor. Just leave the hides and the water bowl in there. Then put the mouse in. Nothing will block the snake from getting the mouse if you take out all the decor and you can attempt training your snake to know when the plants and branches are out of the cage that it is time to eat. Also, you should put a bowl of mouse feed in the snake's cage so the mouse won't bite your snake for food, that is how I did it when my snake ate live and there were no bites at all. But maybe you can try pre-killed, which is when you humanely kill the mouse and then offer it to the snake. Since the mouse still has some of its body heat left, he will think its live and he will go after it, and you would not have to worry about bites from the mouse at all.If offering frozen-thawed or pre-killed, use tongs to hold the mouse and jiggle it around the snake's cages to make it seem alive.

One thing no one has mentioned is that you do not leave the live animal in the cage very long. If the snake isn't interested and you leave the mouse in the enclosure you run the risk of the mouse biting the snake. People vary as to the amount of time, we leave them no more than two hours.
