I read in a comment on Cif that this guy says he heard a scratching on his door and when he went to see what was going on he found a very subdued fox that soon died.

The fox then had thought out his situation, knew in some sense that human beings have medicines? and can stave off suffering and death.
I read a story about an exotic talking bird that had meaningful conversations with its keepers.
