Hello, and thank you for using Petco Pet Education Center, formerly Petcoach. I'm sorry Prince isn't feeling well! Unfortunately, those are quite nonspecific symptoms, and could be consistent with almost any illness. If Prince isn't eating or drinking, and is vomiting, he really needs to be evaluated by a veterinarian. Your vet can determine quite a lot by a good exam, and will then be able to recommend any appropriate diagnostic tests to determine what's wrong. At the very least, your vet can help Prince feel better with supportive care to control his nausea, and give fluids to correct his dehydration. I worry especially with his young age and being such a little guy, he can become dehydrated quickly. I hope he feels better soon!
