On the contrary, an example of Japanese cats being brought out includes that, when people moved from the main land to Okinawa or Amami-oshima island where cats had not existed, they took cats with them, and as a result, some of them became alley cats there and spoilt rare native wildlife including Okinawa rails by eating them, which has been at issue.
逆に日本猫が持ち出された例として、ネコの存在しなかった沖縄や奄美大島などに人々が本土から移住した際に、一緒に猫を連れて行ったため、この地でノネコとなったものが、ヤンバルクイナなど固有の希少動物を食い荒らし、問題となっている。
