There was once a tiger-striped cat. This cat died a million deaths, and lived a million lives, and in those lives, various people owned him. None of those people he cared for. This cat was not afraid of death. One life, the cat became a stray cat, which meant it was free. And it met a white female cat. They became mates, and lived together. Time passed, the white cat passed away of old age. And the tiger- striped cat cried a million times. Eventually, the cat died again. But this time, it didn't come back to life.
