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.

After the “Tatler Tory” bullying scandal, we must ask: what is the point of party youth wings?

A zealous desire for ideological purity, the influence of TV shows like House of Cards and a gossip mill ever-hungry for content means that the youth wings of political parties can be extremely toxic places.

If you wander around Westminster these days, it feels like you’re stepping into a particularly well-informed crèche. Everyone looks about 13; no one has ever had a job outside the party they are working for. Most of them are working for an absolute pittance, affordable only because Mummy and Daddy are happy to indulge junior’s political ambitions.

It’s this weird world of parliament being dominated by under 25s that means the Tory youth wing bullying scandal is more than just a tragic tale. If you haven’t followed it, it’s one of the most depressing stories I’ve ever read; a tale of thirty-something, emotionally-stunted nonentities throwing their weight around at kids – and a promising, bright young man has died as a result of it.

One of the most depressing things was that the stakes were so incredibly low. People inside RoadTrip 2015 (the campaigning organisation at the centre of the scandal) cultivated the idea that they were powerbrokers, that jumping on a RoadTrip bus was a vital precondition to getting a job at central office and eventually a safe seat, yet the truth was nothing of the sort.

While it’s an extreme example, I’m sure it happens in every political party all around the world – I’ve certainly seen similar spectacles in both the campus wings of the Democrats and Republicans in the US, and if Twitter is anything to go by, young Labour supporters are currently locked in a brutal battle over who is loyal to the party, and who is a crypto-Blairite who can “fuck off and join the Tories”. 

If you spend much time around these young politicians, you’ll often hear truly outrageous views, expressed with all the absolute certainty of someone who knows nothing and wants to show off how ideologically pure they are. This vein of idiocy is exactly where nightmarish incidents like the notorious “Hang Mandela” T-shirts of the 1980s come from.

When these views have the backing of an official party organisation, it becomes easy for them to become an embarrassment. Even though the shameful Mandela episode was 30 years ago and perpetrated by a tiny splinter group, it’s still waved as a bloody shirt at Tory candidates even now.

There’s also a level of weirdness and unreality around people who get obsessed with politics at about 16, where they start to view everything through an ideological lens. I remember going to a young LGBT Republican film screening of Billy Elliot, which began with an introduction about how the film was a tribute to Reagan and Thatcher’s economics, because without the mines closing, young gay men would never found themselves through dance. Well, I suppose it’s one interpretation, but it’s not what I took away from the film.

The inexperience of youth also leads to people in politics making decisions based on things they’ve watched on TV, rather than any life experience. Ask any young politician their favourite TV show, and I guarantee they’ll come back with House of Cards or The Thick of It. Like young traders who are obsessed with Wolf of Wall Street, they don’t see that all the characters in these shows are horrific grotesques, and the tactics of these shows get deployed in real life – especially when you stir in a healthy dose of immature high school social climbing.

In this democratised world of everyone having the ear of the political gossip sites that can make or break reputations, some get their taste for mudslinging early. I was shocked when a young Tory staffer told me “it’s always so upsetting when you find out it’s one of your friends who has briefed against you”. 

Anecdotes aside, the fact that the youth wings of our political parties are overrun with oddballs genuinely worries me. The RoadTrip scandal shows us where this brutal, bitchy cannibalistic atmosphere ends up.
