There are many, many reasons why she won't eat..
some can be...
-inproper temps in her 'cage'
-not enough heat for her to efficiently digest her last meal in a timely manner
-just being slow to digest and require feeding again, like some snakes can be
-not used to eating the particular prey item you are offering
-not liking the 'smell and/or taste' of the prey item from the location you purchased it
-not being fully 'adjusted' or comfortable with her cage or her enviorment yet
-wild caught/farm bred animals can possibly have parasites, internal and external, that can result in this
and many other reasons as well.
You would need to provide much more specific information about your set-up before anyone call tell you for sure.
Hope this helps.. thanks much, Joe Rollo - Bci Joe
