Could be RI, even if no one else shows signs of it. Could be an injury caused by the rat? Maybe not something you can see, but something that is causing her body to react that way to try and heal itself? Sounds like a trip to the vet asap is in order.


I feed live to my snakes as well...but I would never leave a live rat in with them for more than a few moments at the most. Live rats (or even mice) left unattended for a long stretch of time can cause severe injuries.
