Welcome to PT! I'm so sorry to hear that Gabby has FIV and that's he so sick. I thought that although cats will have a weaker immune system with FIV that they can still live long fairly normal lives. I know that several people on PT have cats with FIV. He sure is a very handsome boy. I'm a huge orangie fan. I hope that a miracle will happen and he'll become stronger and will be able to gain some weight back. I'll keep him in my thoughts and prayers.
