Whoah! Sorry about the hijack, I just thought that it had already been established that, short of a freak accident, a house cat could not kill its owner. I had assumed that more people had read the book, which is relevant because it has several stories of house cats killing people. Yes, it is a work of fiction, but it shows that other people have given this kind of thing some thought.
You can jump on my back for giving a less then serious answer, but you’ll also have to complain to others in this thread as well.
We have identified secondary means by which a cat can kill a person, both direct (puncture/disease vector) and indirect (moving obstacle).
We have asserted what I believe to be a universal truth, namely that cats would kill us and dance on our bones if they could figure out how.
We have fancifully asserted that a cat could crawl inside us and devour/exterminate us from inside.
I do not believe we have answered the question, could an aggressive or hungry cat kill a person, as an expression of dominance, craziness, or to satiate its hunger by chewing on our sweet, sweet brains?
