I'm sorry that Piper is not feeling well. Sometimes if a pet is vomiting or having diarrhea, but is active and happy otherwise, we recommend withholding food for 12 to 24 hours to see if the symptoms resolve. If it has been two days since Piper has eaten anything and she continues to have vomiting and diarrhea, I recommend a visit to a veterinarian. There are many things that can cause vomiting and diarrhea including inflammation in the stomach or intestines, an obstruction in the stomach or intestines, pancreatitis, kidney or liver problems, among many other things. The veterinarian will most likely recommend blood work and abdominal x-rays to try and diagnose the cause so they know how best to treat Piper. I hope this helps and that Piper gets feeling better soon!
