No, no. no - you're getting it all screwed up. Carnivores have very short guts, herbivores have very long guts. It takes more processing time to extract the "nutriments" from plant life than from meat. Chewing doesn't really matter that much. Cows chew much more than we do (they even cough up curd and chew it some more), but they still need a long gut. I don't know much beyond basic physiology here - I'm certainly no expert. I just know we are not especially well-designed to be strict herbivores (sorry, william...) Rich
