First, welcome to PT. Second, how so very sad to read about your Tiffany. The decision you have to make is not an easy one. In April, we found out our Ralph Syracuse(nearly 14)had intestinal lymphoma. We decided to forgo the chemo, knowing that Ralph would not like going to the vet's several times a week for the chemo and the blood work, etc... Instead, Ralph received prednisone until the day he died(6/15/06). You will make the BEST decision for Tiffany. She has been your dear friend for many years, and she knows you will care for her the best way you can. Prayers for Tiffany and (((((hugs))))))) for you. This is the hard part of your journey together...Sandra
