My cat has an aggressive case of feline injection site sarcoma. Curative treatments are extremely far out of my price range. So, I'm pursuing palliative radiation therapy, to reduce the size of the tumor and her discomfort. She responded really well to this therapy this past summer, so we're hopeful for more. Expenses: She needs x-rays and bloodwork done, which is about $250-300. The radiation itself is partially covered by Petco grant money, but that leaves me $700-900 to pay out of pocket.
