Hi stranger!
I assume you're feeding it, or trying to feed it, frozen/thawed rodents. There could be a few different reasons they don't go ahead eat it.
One of my young retics recently did the same thing with a F/T mouse, twice, just like yours. After two times I replaced it with a young rat & it ate it.
For snakes that are used to eating F/T there could be something about that particular rodent, usually smell or taste. Try washing the rodent with warm water and just a tad of Ivory soap. Any soap may do but I've always used the white bar of Ivory soap. Be sure to rinse the rodent thoroughly.
If the snake has been fed anything live recently it could be the lack of a struggle that triggers the snake to realize that something's not quite right. Tugging on the rodent for a few seconds or more to simulate a struggle can increase the snake's natural instinct and drive it to eat it. But I'm sure you already knew that.
Catch ya later!
Mike
