Oh, Bonnie. I am so sorry. I just saw this, and I am heartbroken. Sebastian was one of my favorite TCS kittehs back when I was just lurking, and he remains one to this day. Don't beat yourself up. You were doing what you could for your beloved boy. He knows you love him. My deepest condolences to you. I am sending a white light to help Sebastian on his journey to the other side. Sebastian, please look in on your family and help them with their grieving. They miss you greatly.
