He has had a reversal in his illness, and I'm taking him to the vet in the morning. Things were really looking better since the vet treated him last week, so I hope this is just a temporary setback.
///Update, afternoon of October 4: The treatments for Ollie's chronic bowel problem are doing their job. Meanwhile, today's vet visit indicates that he has developed pancreatitis. He's on some powerful painkiller until the ailment passes. He has had a little bit of food today without getting sick, and he's mainly resting but has moved around and talked to me a little.///
