News Update:
The cat, now known as "Amazing Grace" is expected to make almost a full recovery from her injuries and has been adopted. She is set to go to her new home on Friday.
The nail was suscessfully removed two weeks ago, and the only problem is that she has blindness in one eye. Vets think that the blindness may only be temporary b/c removing the nail has relieved the pressure being put on the optic nerve.
Police and the local SPCA are still investigating and say they have several good leads.
