In this article, May Safely Graze contributor Danette Wereta writes the New Zealand government’s targeting of feral cats could be disastrous for domestic cats, and there are better ways to protect native wildlife than through the endless killing of predators.
The New Zealand government has added feral cats to the Predator Free 2050 program, which aims to protect native wildlife and boost biodiversity by killing so-called ‘pest’ species.
In announcing the initiative last week Minister Tama Potaka described feral cats as “stone cold killers,” responsible for killing birds, bats, lizards, and insects.
I care deeply about all animals. Of course I want to protect our precious native wildlife, and measures to protect them are essential, but I have grave concerns about the way we are going about it.
Firstly, this latest development will endanger domestic cats. The government emphasises that our companion animals are not part of this target. However, lost cats, cats who flee their home when spooked by fireworks for example, cats left behind when owners move, cats who are deliberately released into the wild, will all be vulnerable. In New Zealand it is illegal to kill a companion animal unless you have a lawful and humane reason under the Animal Welfare Act 1999, but as yet there is no law that requires companion cats to wear collars, microchips, or any other form of identification. Consequently, there is no reliable way to tell a companion cat from a feral cat on sight or behaviour alone (all trapped cats behave the same way). This means anyone who kills a cat based on appearance, behaviour or lack of a collar risks committing an offence by harming a companion animal.
Secondly, adding feral cats to our killing list will not reduce their overall population. This is because of the vacuum effect, which also holds true for other ‘pest’ species, such as possums, rats and ducks. When animals are removed or killed from an area, new animals move in to fill the empty territory. Nature knows the numbers are down, so her solution is to increase breeding, and this can lead to even more animals than before.
Another point I want to make is that the very term ‘pest’ is offensive and harmful. It reduces animals to mere nuisances, stripping them of their inherent value and individuality, implying they’re only worthy of elimination, not coexistence. By using this derogatory term, we justify harming them and legitimise cruel treatment towards them, ignoring the fact that they are sentient beings capable of feeling pain, fear and anxiety like all other animals. New Zealanders, and especially our Media, need to stop using the word ‘pest’ when referring to predators, and replace it with the more accurate and objective ‘introduced species.’
When Predator Free 2050 launched 9 years ago, there was a surge of enthusiasm and community involvement. Grandmothers and small children alike proudly set up traps in their backyards to kill rats and other animals. PF 2050 taps into our nation’s promotion of hunting and shooting as a means of Conservation, but solving problems with a trap, a gun and a poison pellet just makes our culture of killing even more widespread, and ultimately doesn’t solve the problem.
It also seems incredibly inconsistent to target some animals while completely ignoring the environmental damage caused by farming. Many species labelled as ‘pests’ here and globally are only targeted because of their perceived impact on farm productivity, and not because of their impact on native birds. The annual duck shooting fest is an example of this. This selective mindset (based on financial impacts to farming) makes no ecological sense, and ignores the industries that do the most harm.
Shooting, trapping, clubbing, poisoning, and the rest of the ways we torture and kill animals is not only cruel and backward, it does not address the root cause. Actually, PF 2050 is just a funding model: if the money stopped, so would the killing. That alone shows how hollow and unsustainable the approach really is.
Real conservation comes from long-term, systemic solutions, habitat restoration, responsible companion animal ownership, stable ecosystems, and science-based management. Continuing down the path of killing is in fact risky for our native wildlife because it keeps us locked into violent practices and outdated thinking, instead of investing in non-lethal, coexistence-based methods of conservation. Some examples of this are contraception, predator-proof fencing, trap-neuter release, noise-making devices, and the use of visual deterrents, lights, and smells. These are both kinder and more effective ways of controlling introduced species.
Protecting our precious taonga is essential, but the ‘kill kill kill’ mentally espoused in Predator Free 2050 ultimately cannot work. Real progress will come when we redirect resources into root-cause prevention, innovation, habitat protection, ecosystem restoration, and humane, science-based approaches. True Conservation requires coexistence and compassion towards all animals – not blanket eradication of some that is cruel, can’t be achieved, distracts from meaningful solutions, and keeps New Zealand behind the times.

A screenshot came through, and even though I was just about ready for bed after a long, exhausting weekend, I knew I couldn’t ignore an injured animal. I jumped in the car and headed to the spot.

I learned the dairy industry is based on cruel practices. The worst being the removal of new-born calves from their mothers at birth. These new-borns are trucked to slaughterhouses to be killed. The dairy cow is a milking machine. Her maternal instincts are crushed by the yearly removal of her hard-born calf.”
