A couple of things ...

1. Rat pups don't have teeth ... you have NOTHING to worry about.

2. Don't handle her today ... let her be in her cage feeling calm and secure.

3. At around dusk, bring the container with the rat pup into the room with your snake. Place the container (box, bag, etc) on top of or near your snakes cage for about 30 minutes to "scent the room". The smell will help your snake "wake up" and start to get hungry.

4. After scenting the room, carefully and slowly open the cage and place the rat pup away from your snake (maybe other side of the cage) ... this will reduce stress on your snake and help her feeding response by allowing her to "go look for it".

5. No need to remove anything from the cage, leave it all in there. Removing items (water bowl, hides, etc) could cause stress.

6. Carefully close the cage up, back up slowly, sit down and relax. Sudden fast movements or loud noises could spook your snake.

Good luck.
