The Aoshima is a small island located in the Miyazaki prefecture in Japan and has only 20 inhabitants. Its uniqueness is that roam the island about 120 stray cats, a ratio of a resident for 6 cats. Cats were introduced to the island originally to hunt mice, but multiplied massively. Of the 120 cats, only 10 have been castrated. Cats survive searching in rubbish bins and few tourists who feed. The island has no hotels or shops, but the presence of cats attracts many tourists.
