Naah I took him out today when I cleaned the enclosure (again) and he seems his normal, fine self. Much less stinky up there now, too.
Its the paranoid mom in me, as always

I never much looked into IBD as he has never given me any reason to worry before. Had to ask in case I was ignoring something serious. But after it was clean he seemed fine.... Went right on back to his hide. Ill still be keeping a closer eye on him for a few days anyhow, just to ease my own mind.
