My BP is afraid of her F/T food?

[Bogertophis]

Ive had her for about a month. She’s about 7 months old. The breeder didn’t tell me much about her feeding record, other than she was taking f/t mice. I had offered her mice initially but ended up refusing the ones I offered. That’s when out of desperation I tried that rat fuzzy and she ended up eating it after leaving it with her for a little while. But now she’s even refusing those. I will admit she looks way more interested in the rats than the mice.

Maybe I'm reading too much into this, but how many times have you offered her food in the month you've had her? Have you handled her at all?
Snakes get too stressed to eat when we keep offering them food (with or without handling): if they refuse a meal, do NOT offer again for at least a week.

For best results, it's recommended to do no handling until a snake has fed 3 times at normal intervals. And it's also best NOT to offer any food for the first week or 2
while they are settling in. It seems possible to me that your initial failure (to get her to take f/t mouse) was because she still had NOT "settled in" yet.

She was then hungry enough to chance the rat you offered, but she still has a preference* for mice. (*feels more comfortable pouncing on) So now she's confused,
and if you've offered repeatedly (& too soon), it's only adding to her stress.

For best results, you always want to be offering what a new snake has successfully fed on before, and only after giving them time to settle in. Sure, some snakes will
eat right away...and some of us with years of experience may short-cut these "rules" because we can deal with whatever happens, but when you're new & your snake
is new, it's best to follow guidelines.

I know how badly you want her to eat & thrive & be a great pet for you, but you'll need to be patient...snakes are living creatures that can easily stress & frustrate you.
Sometimes the best thing you can do is ignore them for a week...remember they live solo in the wild, & they're usually quite shy.
