In the district of Itacuruçá, in the Sepetiba bay, south coast of Rio de Janeiro, there is an uninhabited island 5 kilometers wide, which in recent years has become a tourist attraction. Ilha Furtada is inhabited only by cats, hundreds. For this reason it was renamed the Island of Cats.
According to estimates, since it is impossible to count how many cats currently live there, there are more than 700 felines living there.
