Certainly if we want to maintain current levels of biodiversity. Cats did not evolve in that environment so the usual checks and balances of evolution are not there. Feral cats don’t seem to be as much as an issue where I’m from, probably because of the abundant coyote population. Cats don’t last long outside with those around. Adding another apex predator to the mix might do more harm than help in New Zealand’s case. Better just keep Mr. Whiskers indoors.
