I got a girl from a small local breeder a couple of weeks ago and she is settling in nicely. I will be offering her food this weekend. I was told that she is a mouse eater and that the guy I got her from tried a few things to get her to switch to rats with no luck. I know some snakes will always be a mouse eater vs rat eater. How long should I try to switch her over to rats? And what is the best way to do so?

thanks!
