Hi, I am wondering if food intolerance can cause chronic diarrhea in cats, even when the source of food has stopped for weeks. Also is grass eating a sign of GI upset in cats? Thanks.

Yes to both questions. Unfortunately intolerance is usually against a variety of different food sources and not only one.
