Off the eastern coast of Japan lies the tiny island of Tashirojima. In the 50′s it had over 1,000 residents many of whom kept cats to manage the mouse population. Now the human population has decreased to about a hundred, mostly over 70 years old. As you can imagine, the cat population has not followed that same trend.
It is an island ruled by cats, and it has been now for long enough that there is a culture developed around the animals with rules like No dogs allowed. There is even a cat shrine and a few cat-shaped buildings. And to top it all off, vets visit the island to make sure the animals remain healthy.
But recently, to the south, another island has joined the ultra-elite club of “cat islands.” Aoshima has about 15 human residents — again, like on the other cat island, almost all old and dying out. Not the cats, though. They’re fertile as ever and continue to make the island their home, despite not having had owners for generations.
