Humans, since over 300,000 year ago.

Someone who’s very hungry?

Also smoked horse is awesome.

I don’t know about eating a whole horse but horse meat is sometimes used in meetvursti and similar meat products and horse meat is sold as cold cuts here in Finland. I like it

I checked and the meetvursti I have in the fridge right now has horse meat in it. Apparently bred and slaughtered in Argentina.
