Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting is sometimes seen with conditions such as inflammatory bowel disease, dietary indiscretion, pancreatitis and chronic kidney disease, among many other conditions. Given Mugsy's young age and the fact that he is otherwise doing fine and this is sporadic, dietary indiscretion appears more likely. 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!
