Should New Zealanders kill their kittens to save their native birds?

Domestic cats are furry murderers, argues a New Zealand businessman who is spearheading a campaign to get his fellow Kiwis to give them up.

'Save a Kaka, kill your cat' is the message of New Zealand businessman Gareth Morgan, who has started a campaign to rid the ecologically isolated islands of murderous felines in attempt to stem the dwindling numbers of native birds.

For 80 million years, the archipelago has been separated by ocean from any other land. Apart from one mouse-sized animal which went extinct around 16 million years ago, there have never been any land mammals on the islands (although there remain two species of native bat, and plenty of whales, dolphins and seals). That left an ecological niche which was largely filled by birds, being some of the few animals which could reach the islands after the seas split them from the rest of Gondwanaland.

New Zealand has some of the most unique, and clueless, birds in the world. The Kakapo is a giant green parrot which eats grass and has sex with Stephen Fry's head. The Kiwi is the size of a chicken, and lays an egg so big that the female, for the last couple of days of her incubation, has no room for any food in her stomach and must fast. The Kokako is a semi-flightless bird which sings duets in breeding pairs for hours on end and occupies the same niche as a flying squirrel.

None of them were ever exposed to predatory land mammals until the Maori arrived in the 14th century, and so they have very few natural defences against them. The introduction of mice and rats was bad enough, but once cats appeared, it was nearly over. The Kakapo and Kiwi are now critically endangered species, each limited to a few islands which have been cleared of introduced predators — but there's hope for the Kokako, as well as the Kaka and Weka which are also under threat. And one thing which would help is New Zealanders giving up their cats.

Gareth Morgan has started a campaign, Cats to Go, which is pushing for that aim. He writes:

New Zealand is the last refuge of a huge range of bird species, we’re famous for our claim to be clean and green, and some of us have recognised the huge economic benefit, let alone the ecological dividend, from achieving a Predator Free New Zealand.

But the vision is flawed. Almost half of Kiwi households have a cat (or two) making New Zealanders the world’s biggest cat owners. Cats are incredibly effective hunters and are wiping out our native birds.

… Like the parent of a bully saying that their little Johnny would not behave like that, if you’re a cat owner reading this, you are probably thinking that the above statistics don’t apply to your cat. The fact is that your furry friend is actually a friendly neighbourhood serial killer.

He doesn't actually want people to kill their cats directly — though he emphasises that "that is an option" — instead proposing that people put bells on their cats to warn birds, keep them inside, get them neutered, and, above all, not replace them when they die.

Even if it works, there is a long way to go to make New Zealand safe for its native birds. Rats, mice and possums are all widespread and causing damage of their own. But a cat-free New Zealand might still be worth fighting for.

How tribunal fees silenced low-paid workers: “it was more than I earned in a month”

The government was forced to scrap them after losing a Supreme Court case.

How much of a barrier were employment tribunal fees to low-paid workers? Ask Elaine Janes. “Bringing up six children, I didn’t have £20 spare. Every penny was spent on my children – £250 to me would have been a lot of money. My priorities would have been keeping a roof over my head.”

That fee – £250 – is what the government has been charging a woman who wants to challenge their employer, as Janes did, to pay them the same as men of a similar skills category. As for the £950 to pay for the actual hearing? “That’s probably more than I earned a month.”

Janes did go to a tribunal, but only because she was supported by Unison, her trade union. She has won her claim, although the final compensation is still being worked out. But it’s not just about the money. “It’s about justice, really,” she says. “I think everybody should be paid equally. I don’t see why a man who is doing the equivalent job to what I was doing should earn two to three times more than I was.” She believes that by setting a fee of £950, the government “wouldn’t have even begun to understand” how much it disempowered low-paid workers.

She has a point. The Taylor Review on working practices noted the sharp decline in tribunal cases after fees were introduced in 2013, and that the claimant could pay £1,200 upfront in fees, only to have their case dismissed on a technical point of their employment status. “We believe that this is unfair,” the report said. It added: "There can be no doubt that the introduction of fees has resulted in a significant reduction in the number of cases brought."

Now, the government has been forced to concede. On Wednesday, the Supreme Court ruled in favour of Unison’s argument that the government acted unlawfully in introducing the fees. The judges said fees were set so high, they had “a deterrent effect upon discrimination claims” and put off more genuine cases than the flimsy claims the government was trying to deter.

Shortly after the judgement, the Ministry of Justice said it would stop charging employment tribunal fees immediately and refund those who had paid. This bill could amount to £27m, according to Unison estimates. 

As for Janes, she hopes low-paid workers will feel more confident to challenge unfair work practices. “For people in the future it is good news,” she says. “It gives everybody the chance to make that claim.”
