Dale ate about a quarter of his dinner last night (I did give him his insulin right after), and left the rest untouched. Hasn't eaten since then. Usually he is screaming for his food. He vomited at about 7 hours ago. I took him to the vet and they treated him for dehydration and nausea. There is no fever. They tested his blood sugar and it's quite high but I can't give him insulin until he eats. I will take him in again tomorrow if he hasn't eaten, so I guess I am just looking for any other ideas and well-wishes in general. Am I freaking out way too early? It's just so out of character for him not to want to eat!
