Coco needs to be examined by the veterinarian today. The vomiting could be due to many conditions including eating something he shouldn't have, bacterial over growth, parasites (worms and giardia) or even something more severe like organ dysfunction or intestinal blockage (which is fatal without treatment). Try to remember to take in a stool sample. The doctor will check him and recommend diagnostics based upon the examine findings and history. Many times a bland diet can help and then a slow, gradual introduction to the normal food can be done. A bland diet can consist of 25% boiled white meat chicken and 75% boiled white rice. This should all be plain. I hope Coco starts feeling better quickly! Please feel free to post any additional questions!
