Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting and inappetence are sometimes seen with conditions such as inflammatory bowel disease, dietary indiscretion, pancreatitis and chronic kidney disease, among many other Possibilities. It may be something as easy as just changing his diet to something that he can tolerate better. However, an examination by a veterinarian as well as minimal diagnostic data would be needed to rule out more concerning things. You can start by changing his diet to a sensitive stomach type diet. If no improvement, have him examined by a veterinarian to start therapy if needed based on findings. Good luck!
