Aoshima, also known as Cat Island, is an island in Ehime Prefecture, Japan, known for its large number of feline residents. Felines have been reported by news outlets to outnumber humans by ratios between 6:1 and 10:1, but as elderly inhabitants of the island have died, the ratio has greatly increased to almost 36:1. Felines were introduced to combat rodents on fishing boats, but remained on the island and reproduced in large numbers.The feline inhabitants of Aoshima are fed by food donations from all over Japan. The cats also eat the small creatures of the island and some food from visitors.
The island is roughly 1 mile long. It was formerly part of Nagahama in Kita District, but as of 2005, is part of Ōzu.
