If this was caused by a food change I would expect him to be back to normal by now. There may be something else underlying going on here that is the cause of Zebco's diarrhea and weight loss, such as intestinal parasites, pancreatic disease, diabetes, or even thyroid disease. I would recommend taking him to your vet for a through examination and potential tests (bloodwork, fecal exam), to hopefully identify the underlying problem so that he is treated appropriately. In the meantime I would suggest feeding Zebco a bland diet of boiled plain chicken and rice or cottage cheese to help settle his stomach a bit. You can also try adding 1-2 tsp of canned pumpkin (not the pie filling) in his food daily to add fiber and help harden the stools up. Best wishes with Zebco and I hope he feels better soon.
