Should've called it Yce.

A substantial amount of people were farmers/lived close to nature though. It's just... pet food wasn't a thing, in the best case you might toss some meat leftovers (though I suppose those would mostly go to the dogs and pigs). Cats roamed and are pretty capable of keeping themselves fed when they're healthy. I doubt it's as much a question of people keeping cats than cats staying around sources of easy food (vermin)/warmth/scritches behind their ears. You didn't need to be able to afford cats, they can take care of themselves.

Same as with your pet cat. If it's a freeroam, it'll hunt anyway regardless if you feed it or not. My previous cat was semi-freeroam (couldn't get out the connected backyards) and at one point he took the neighbours' rabbits home. Over a 3 meter/10 foot wall. Mind you, he was well-fed and lacked for nothing. My current is indoors only, she attacks anything on 4 legs on sight. Including the neighbour's German Shepherd. Hunting instinct is big in cats and never went out of them.

If treated the same, yes. Cats haven't changed all that much. And they survive well enough on their own as strays that they quickly become a pest when not controlled.
