Therapy for Serenity, the broken kitten

We found Serenity outside IHOP alone, cold and scared with no sign of a mother or owner. We took her in only to discover this 7 week-old kitten had a broken front leg. After a visit to an emergency vet for x-rays, it was decided that she would require surgery. Now it has been determined that the injury is too old for a surgical option, and a non-invasive therapeutic approach will help her regain most of her leg function. We are fostering her through her recovery, and need funds for her care and therapy.  Our goal is to raise at least half the costs of vet visits, therapy, x-rays, and care. She is doing quite well and no longer shows signs of pain to the leg. Any help you could give would be great in continuing her care and treatment.
