i am soo sorry about the grim diagnosis. the thing most pet owners hate to see is there little friends suffer. Specially if we know whats going on and they dont. I find it helps to talk to ur hammie about whats going on. I had to watch many of my friends die and they all seem to understand. the thing that u can do is make hammie comfortable and be there for him/her. Who knows maybe the tumor on hammies adrenal gland is benigned. meaning non cancerous. Hammie and you are in my thoughts.
