I am confident that I’d win against the cat if it didn’t catch me asleep, but I am also aware that it can cause me damage if it is unhappy with me.
Yeah I can’t imagine a cat taking a man down and killing him.
Even asleep, they would have to claw or bite to the arteries on the neck and I don’t know if they have that kind of capacity.
But since my cat as the biggest 11 year old baby in the world I don’t have to worry :)
