Acute vomiting and diarrhea, especially with poor appetite and lethargy, are certainly cause for concern. This could be caused by an infection, something stuck in Max's intestines, or a metabolic problem. At the veterinarian, they will examine him and probably take x-rays and run some lab work to look for the underlying cause of Max's issues. I wouldn't wait very long to go to the vet since Max is so young and small and so can become dehydrated quickly. See if you can get in for an exam today.
