Force-feeding treif to cats

Well, finally got something like a diagnosis on Grendel: he has pancreatitis. We switched his diet from Hill's I/D to Hill's W/D, which is basically pork liver. It's actually real low in fat and should therefore help relax the pancreas. He'll need to be force fed for a while and subcutaneously hydrated. Hopefully we can get it under control before it does much damage. I'd hate for him to wind up diabetic from this.
