Its probably true of most animals. I raised a couple of pigs and we intentionally never fed them any meat, even though they'd probably eat it, because we didnt want them to get a taste for it
> You don't want to be the farmer who falls over in his pig sty.
This is the real reason for the panic when Dorothy falls into the pig sty at the beginning of the Wizard of Oz. The pigs would crush her and eat her. (But in the movie, her dress doesn't even get dirty!)
Apparently it's still a thing in places like rural India for people to squat to poop out in the fields, and then risk being bowled over by a pig rushing over to eat it.
They truly will eat anything.
As far as meat goes, they are not just scavengers - I've seen videos of wild pigs chasing after rabbits, actively hunting them down.
I'd never head of those Chinese "pig toilets", but it reminds me of a Chinese friend who said that growing up (maybe still?) it was common practice in the villages to feed infant poop to the pet/village dogs.
Horses are clearly and very much into the whole cowboy thing, they LIKE chasing down cows and catching them, some do it all by themseves and catch cows by grabbing there tails and hauling them around that way.
Horses are panoptic motherfuckers and are startlingly good stalkers, which I learned living in close quarters with a horse needing to chase them away while doing stuff in the padock, but have them reapear, it took very precise sneeky peeking to catch them moving towards me, as they only move when I am not looking, which led me to the only viable deterance, which is to pretend that they are invisible/of zero importance
which un nerves them, but so much as one eyelash of a look at them is taken as an invitation to partisipate, fuckers.
Horses also work well with dogs, and for arabians in Arabia, dates and dried fish were used as feed for both.
note, live with an arab/percheron cross far enough out that there is a wide representation of wild critters, and most everything is on most everythings menue, depending.
And one of my more radicle, radicle friends would say, "we will eat the vegans first, they are slow and weak", refering to what to do durring an opocaliptic event, and until they could get out to my place in the country.
