She ate without mouse scent! Fun fact, it's been two nights since my BP refused to eat the rat. I decided to try a new rat tonight due to the fact that she has been searching around for food. I didn't scent the rat with a mouse. What I did different than all my other feedings is that (1) I heated the thawed rat with a hair dryer instead of using warm water, (2) I didn't remove her hide to feed her, & (3) I turned off the lights in the room.
Hopefully this will continue without the for a mouse. Thanks for the suggestions, folks!
