New Zealand has announced plans to eradicate feral cats by 2050, as part of efforts to protect the country’s biodiversity.

Speaking to Radio New Zealand on Thursday, conservation minister Tama Potaka said that feral cats are “stone cold killers” and would be added to the country’s Predator Free 2050 list, which aims to eradicate those animals that have a negative impact on species such as birds, bats, lizards and insects.

Cats had previously been excluded from the list, which includes species such as stoats, ferrets, weasels, rats and possums, but Potaka used the interview to announce a U-turn.
