Why herbivorous animal have large small intestine as compare to carnivore

Answer 1

herbivorous animal have large small intestine as compare to carnivore because plants contain cellulose which is difficult to digest as herbivors eat plants they need to digest them , long intestines helps them in this process 

carnivores eat animals and it is easy to digest so they have small intestine

Herbivores eating grass need a longer small intestine to allow the cellulose to be digested. Whereas Meat is easier to digest, hence carnivores like tiger have shorter small intestine.
