Save Miss Ginger

This little girl was found limping and very scared at my work, we have been feeding her for weeks. Finally we managed to cage her. We named her Ginger and took her to the vet she has a broken leg on TWO places and it will cost upwards of $3000 to fix her. We have many people willing to keep her, but the vet bills are too much. We could REALLY use the help!! Anything will be appreciated!!
We will give this little girl a great home once she is healthy! Please help!!
