It is recommended to take LIttle Bear to the veterinarian to be evaluated. There are many different causes of vomiting. He may have a gastrointestinal upset, Pancreatitis, Foreign Body, etc. Your veterinarian will be able to do a complete physical examination and determine if any and what diagnostics are needed.

    If he is vomiting and is weak then he should be examined by a vet to determine the cause. He could have an infection, parasite, obstruction, pancreatitis, endocrine disease, etc. It sounds like he could be dehydrated and your vet can give him fluids to re-hydrate him. He may also need an anti-vomiting injection, antibiotic, antacid, and gastrointestinal protectant to help.
