Most things are omnivores. Some predators like cats are obligate carnivores (must eat meat to survive) but most creatures get nutrients wherever they can.
There's a video of a deer straight up eating a baby chicken. It's not built to be a predator, but when the opportunity presents itself...
Lefty omnivore here. Not hating on vegans just on the militant ones. I think vegan is the way to go but I'm not ready for it yet and hate being talked down to about it.
You can make incremental changes without fully committing. Vegans might talk down to you about it but are you doing it for them or are you doing it for you / the world.
