Chris-- Ben and Jerry's is LOADED with fat and dairy. I am assuming it's the general lactose-intolerance that caused the initial diarrhea. About futons-- I have three ferrets and a futon on a frame. Not a lick of trouble in almost 3 years! After they play out of their cage all evening I pull up the edge of my futon mattress and always find the group sleeping in the same corner.! amy [Posted in FML issue 0822]
