It is fibrosarcoma. It is an aggressive cancer. Basically we just keep him comfortable until the tumor grows back and then say good bye. The doctor said maybe 3 to 6 months. He isn't eating much food at all. He will devour treats though. I bought some pill pockets, and he LOVES those. He wasn't crazy about the transfer factor in them though. I'm going to keep trying. He ate about half of a capsule. I'm cooking some chicken for him. I will use the broth and perhaps entice him to drink that with some TF in it. Or I may try to see if a pharmacy can compound part of it into something he'd like. I'm not going to torture him with it. I remember Tiger and Barney not enjoying it either. We'll just do our best and enjoy our time together the best that we can. Thanks guys.
