gosh, my worst nightmare... since i moved in with my Mom (she is elderly) once in a while we have a mouse in the house, Rosi is my hunter 

 she never caught one thank god. Mom use to have Decon out, but quit when we moved in , now we have to use a trap in the Utilityroom where they cant go in, gross !!! Hope your Baby is ok, and thank goodness you took her to the Vet !
