Adult Ball only eats mice

[Big Gunns]

I have a adult ball python that will only eat live mice I haven’t tried to get her onto f/t just yet I just want to get her onto rats at the moment.
She takes 4/5 mice a week depending on the weight of the mice. I have rubbed mice on the rats to get the scent on them but I am thinking that it’s just the size of the rats that intimidates her.
Does anyone else have a ball python that just refuses to move onto rats?

Yes...don't worry about it. There are many large breeders that have snakes that will only eat mice. They're fine. You can continually try to witch it over, but your snake will be fine if it never eats a rat for the rest of it's life. Big Gunns 100% guarantees it.
