We took my cat to the vet and we were told he may have pancreatitis. He is eating less and projectile vomiting often. The vet gave some pain medication and that was it, they just told us to watch what he eats. His symptoms are continuing and i’m very worried for him. He’s always pretty calm so it’s hard to tell if he’s in pain or not.
Are there similar symptoms that can turn out to be something else? And are we able to treat this or does he need to be hospitalized?
