Jill needs some help!

... I also agree to try leaving the food overnight as the next step to try. Generally they will prefer mice over rats to start, if she was taking f/t mouse hoppers for you before, I'd stick with those (or smaller as you tried).

If leaving overnight doesn't work (some really do just like to take it when everything is quiet and still), the steps we take, with usually good results, are:
First presenting prey a bit away from them where they can see it, hold with tongs on the ground and wiggle like a baby live pink would be... just helpless and wiggling around.
If some interest but not a lot, move closer until it's actually touching the boas mouth. Sometimes this gets them to just go ahead and bite it.
If no interest, actively moving away or just ignoring completely, then we bump it against and annoy the boa's tail with it, gets them irritated but it sometimes causes them to go "okay you lil bugger!' and bite and wrap and finally feed.

We always try offering like the first step. Then leaving overnight. If still nothing, next week we try step 1 and then move on to those last two I mentioned.
Normally once a baby starts feeding, then they are good so I hope your girl comes around soon now that she's back in the smaller size tub. *fingers crossed*

I agree. Snakes don't all "read the manual" to respond the same way...I do my share of varying the presentation...I've seen plenty of snakes that do best with a little
"tap on the shoulder" (with the prey) so they turn & bite (yes, this is defensive, but if you stand very still, most snakes realize "Hmm, this tastes pretty good" & they eat.

I've also gotten snakes to eat by sneaking the prey right up to their face & barely touching their jaw, & wham! they bite it, wrap & eat. Whatever theatrics it takes to get
YOUR snake to eat is worth it & just part of the game. Just do your best to be "in the background". And offer at night if that's what your snake would do in the wild.

I've raised quite a few rosy boas & also worked with some w/c rescues...they are snakes that can frustrate owners, but there's always some in EVERY species that just
want "special treatment"...it's up to us to try until we figure out what works. Once we do, they often grow out of being so difficult...it's just a matter of getting them going.
