Man wants to ban cats

<span style="font-size: 15px; line-height: 24px; font-weight: bold; font-style: italic;">How does Gareth Morgan propose that New Zealand rid itself of cats?</span><br><br>

Cats would be shipped to other countries.
People who own cats would be forced to leave New Zealand and take their cats with them.
People could keep the cats they have now, but not allowed to get any more cats.
Cats would be put in special zoos for cats.
