@datarama @BackFromTheDud @rufustheduck I had to go digging what was the story and where did I read it, and turns out my memory and imagination had set the domestic foxes back in time, as they apparently were hunted extinct as part of the genocide of people who kept them, as late as 1880's.
The blog post where I first read about them was from 2010's, so I guess ten years is enough to blur even interesting things in memory.
