Predicament with Mercy

[Klaire]

Okay so long story short (she was switched to rats at a young age) iv'e kept her on rats ever since i got her but today i was looking for a pet store that sold cheaper frozen rodents anyway i found one called and asked if they had the rats i was after the man on the phone said yes so i drove all the way there only to find out they have all sizes of mice and only really large rats! i was a little pissed off and i couldn't leave there empty handed as the other normal pet barn i go to was closed so i had to get some damn mice. now my problem which you all probably have guessed by now is this. she has always been on rats and i took a gamble purchasing the mice. what if she doesn't eat the mice? or what if she does then i can't get her to switch back over to rats like she was originally on? i'm worried as her type jungles are notorious for being difficult to switch over but i have hope since she already got switched to rats once i feel when i'm done with this pack she will switch over to rats again with her next pack. anywho if i have trouble switching her back to rats does anyone have any advice to help her make the transition again? and has anyone else experienced switching their snakes over more than once for whatever reason? i appreciate any comments/advice/opinions !
