Just like us when they become ill or are severly injured appetite lose is almost always a common reaction. The only way to keep them from starving is to force feed. I had to do the same thing to my female Pacman Grif. She didn't like the meds either. I did feed her a high calorie cat/dog food through a seringe. She actually liked that a lot and would willingly allow me to open her mouth when she saw what was in the seringe. Very easy for her to swallow and digest.
