Poor Chunky. We had a cat who would also fast while at the vet's. Fortunately we never had to board him more than a day or two when he needed medical attention while we were away. Perhaps you can send him with a once-worn T shirt or something that has your scent on it. That might not persuade him to eat, but could be a comfort. Too bad you cand't get a letter from your doctor saying he's a "seeing eye cat" and put him in your carry-on :icon_biggrin: .
