Is that why cow poop is gooey and not like... Well, like a banana shape?

Why would we not have fiber?

Thank you this is nice.

This is fascinating. I did not know this.

Then are humans herbivores? If we are vegetarian, and eat some plant stuff but not all, why? Why don't we get the special enzymes? It'd be cool to munch on grass. We already eat vegetables so what makes the key difference?

Cows and Buffaloes literally chomp down on dried grass. DRIED GRASS! Why didn't we get those enzymes? They sound cool.
