Poor Brutus' digestive system needs some readjustment, especially given that he's on this bland diet. I think it's okay that he's not having normal poops at the moment. I'm glad he's going at least. Give him some more time and the fact that he hasn't vomited is a very good sign. I know when Tate or Finn have GI problems and i put them on bland, they will not have their "normal" poop habits right away either.
