Slow news day?
This sort of thing happens all the time. Especially in rural areas, like where I live. It’s a “young people” thing. A hundred years ago it was beyond common. And a thousand years ago>? Fuggetaboutit.
Not all rural areas have human animals like this.
Rural Amish, or just sick people in general? I can see not liking cats, and culling them with a .22 rifle or something along those lines. Letting a couple of pitbulls have a go at it while you watch in enjoyment is a special kind of messed up.
