maybe via infection, and over a few days at that. unless the cat gets spectacularly lucky, it can't scratch you badly enough that you bleed out on the spot. cats typically kill by severing the neck vertebrae with their jaws. a house cat isn't strong enough to do this to a human.

Maybe a paralysed human.. really?

While I'd never want to try it a swift punt would end a cat attack surely

If you don’t get prompt medical attention for the likely infection from the bite, sure.

But that’s a bit of a delayed effect.

Soul killing doesn't count.
