Being an herbivore is a pain in the ass even when you're not a koala and choose to specialize in eating one plant so hard that it makes you retarded because plant material is way harder to digest than meat, it's why so many herbivores have massive guts that are solely dedicated to processing food that they've already chewed up and spit out 5 different times, and even then a lot of it doesn't get properly digested which is why so much herbivore poop is basically just giant chunks of undigested plant matter. It's like nature's corn. They can live off of plant matter just fine, but they need supplements every now and then, it's why you see deer and giraffes just chewing on bones for calcium. These animals wouldn't be engaging in this behavior without some kind of benefit, a cow eating a snake carries an inherit risk of the snake being venomous and seriously injuring or killing the cow, but the cow does it anyway because he's a culinary visionary who wants to cut out the middle man between spaghetti and meatballs.
