Hey Moses! :-)
Glad to hear your Coastal is doing well and is recovered nicely.
What about trying 2 prey items half the size of 1 you normally give her, but have one rat and one mouse. Maybe defrost them together and then rub the prefered one on the other one. After getting into feeding mode, might be happy to down both, got nothing to lose...
Oh, I'd probably wait till after shed, but that's just personal preference.
