Let me know if I am misunderstanding here - but if I am reading your posts correctly it sounds like your snake will eat F/T mice. If that's the case, why the emphasis on feeding rats? Why not feed mice? There's no significant nutritional difference between mice and rats - she's just a baby; various ages of mice will be a perfectly appropriate size for her for a very long time. As a side note, I have an adult Jungle Carpet Python who just does not like rats at all - he loves his mice, and continues to do very well on them.
Thank you for being open to the feedback that you are trying to feed too frequently! Waiting a week between offering meals will be better, as with just a couple of days between feeding attempts you risk stressing her and getting her into a cycle of refusing meals.
