Re: Lions can survive if they are feed with vegetables

Lions and other felines can theoretically survive short-term on a 
vegetarian diet, but would need extensive supplementation to survive 
long-term.  Felines have a very high requirement for certain amino acids 
(the building blocks of protein) that are only found in meats. If these 
were supplemented, the chances of long-term survival would increase.  Their 
ability to digest some plant materials is also limited because of a lack of 
the correct enzyme in the intestinal tract.
