Japanese endangered bird species have taken a hit, with over 30,000 of them presumed to be preyed upon by cats - this vividly underscores the increasing biodiversity crisis, and why conservation measures need to be urgently addressed.

Preserving biodiversity and wildlife conservation are important subjects in Japan, and an issue like this is likely to generate substantial public discussion and concern. In Japan, feral and abandoned cats are quite common and their effect on local wildlife has been a subject of continuing study. Several measures such as TNR (trap, neuter, and return) strategies are being undertaken to address this issue, and the government has been mulling whether stricter regulations need to be implemented on pet ownership and abandonment.

In the U.S and E.U, the impact of domestic and feral cats on bird populations is also a subject of significant concern. Various organizations are involved in strategies like neutering and creating cat-free zones to protect bird populations. The challenge is similar in all these regions, balancing the cat populations and their impact on urban wildlife.
