Have you made sure her cage temps. are within safe & proper range also? You mentioned the outside temps. have warmed up...keep in mind that a snake that
is too hot will also want out of their cage: I assume her cage heat is controlled by thermostat? otherwise if the room is now warmer, her cage may be too hot.
(I'm just making sure- every now & then someone isn't using a t-stat-)
It mostly sounds to me like she is starting to stay in what we call "feed mode"...still looking for more food, even when full. A bit like us "needing" another cupcake...
Snakes may stay pumped up for more food for a few hours to a day or so after they've eaten...do NOT give in & give more food, even IF the meal was too small.
Adding more food to their digestive tract after some prey is partly digested will usually result in a regurgitation of both items...you really don't want to 'go there'.
It's bad for the snake, & super-gross for you to clean up.
