GI Stasis and megacolon

Question
Hello,
I have a 3 yo Holland Lop male rabbit named Sammy. Sammy has had a history of abnormal poops and periodic stasis. Well I have done some research and believe that he is a megacolon rabbit as he fits the textbook description. Anyways, he is having a bout of stasis again and it is taking a lot longer for him to recover. I work for a vet and am treating him at home. I first noticed him go off his feed on Monday of this week. He had fewer poop pellets as well so I knew we might be heading for trouble again.
 I started simithicone Monday night and increased greens which he picked at. Tuesday I took an xray to see what was going on and sure enough it looks like stasis but no blockage. I have him on Reglan, metacam, simithicone, benebac, and Sq fluids since Tuesday. Last time this occured it only took 3 doses of reglan to produce poops. It is now Saturday and still no poop.
 The very odd thing though is he is acting completely normal today. His appetite returned and he is eating tons of greens and a little hay, he is drinking water and was running around a little at play time. The no poops thing worries me though. He goes to the litter box to pee but there isn't any poop. My other rabbit is fine and I see her poops which are normal. I took another xray Friday to be sure there still wasn't a blockage and still couldn't see one though there was food in the stomach. I would think if he was blocked he'd be more depressed and not eating or drinking. This has me confused and on edge. I hate waitning but know I need to be paient. Surgery isn't an option either as there is a poor prognosis anyways. Is it possible if he is blocked for the fluids and treatments to still work? I still doubt he is blocked because as I right this he is running up and down my stairs and chasing his cagemate. How much can he eat without pooping? He's got me confused.

Answer
Dear Becky,

His behavior is the most important indicator of his health.  If he's now eating, I can guarantee that his guts are moving.  (Having experienced ileus firsthand, I can tell you that when your intestines are not moving, the very *thought* of food is nauseating.)

We've seen bunnies take a few days to start producing poops when they have suffered a bout if ileus.  Expect to see small, possibly mucous poops at first, and then they'll become more normal with a bit of time.

As long as he's eating and acting frisky, things are good.  If he really is a "Cowpoop Syndrome" bunny, then you might wish to ask your vet about periodic lactulose dosing, to keep his intestinal contents well hydrated. The critical thing with these bunnies is to keep the gut contents hydrated to prevent intestinal blockages.

Hope he's fully recovered soon, and stays well for as long as possible!
