Oh, Sue, I am so sorry to hear that there is yet another challenge for Killian and you. I don't know of anyone who could have cared for all his problems with any more of a concerted effort. It seems you have one determined veterinarian as well. In the process, you have become quite an expert, and honestly, I think you have worked a miracle in managing to keep Killian alive and functioning and enjoying life despite having almost everything in the book having been thrown at him. Keep up the good fight.
