If you've never tried canned tripe, you could give it a try. It kept my boy, Cruz, eating for a good while in the last stages of CRF. I fed Cruz the Solid Gold, Tripett, and ZiwiPeak. He liked ZiwiPeak the best, but ate all three brands pretty well. Ideally raw tripe would be the most nutritious, but it's extra stinky and messy, so I would try canned first. Sending good thoughts.
