You need to take Hank into a vet right away. It's quite serious he hasn't eating for three days and is vomiting. He could have a severe GI illness, may have eaten something rotten, or could have a foreign body. He needs veterinary care immediately to diagnose what is causing these symptoms so he can be treated. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck, I hope this helps!

    Hello, thank you for your question about Hylos. Lack of appetite and vomiting can be caused by a number of different underlying causes. It can be secondary to systemic problems such as liver/kidney disease or due to a GI problem such as infection/inflammation. Since Hylos has been vomiting for some time now and he is not interested in eating food I would be very concerned that he is becoming dehydrated. I would recommend having him seen by a veterinarian so that they can examine him and discuss the need for additional diagnostics and treatments. Hope this helps!
