If my cats eat me after I'm dead, what do I care? And I've actually discussed this with my friends and they know I'm okay with it and not to blame the cats.
Oh, I didn't think you were! It's just I know that with wild animals, they'll kill them if they eat humans, and I've known people who are squicked out by the idea of having a pet that might've eaten someone. And I wanted to (a) let my friends know it was okay with me and (b) feel out their opinions in case someone would be squicked out if it happened. I know that is incredibly unlikely to ever happen, but it is a possibility and I wanted to account for that in whatever arrangements I set up for the cats.
My elderly mother used to say her beloved cat helped her to remember to be super careful about falls "because otherwise I'll be lying on the floor and Puss here will eat me".
