Journalists Need To Stop Citing The Bunk Studies Blaming Cats For Annihilating Wildlife

Free-ranging cats do have a negative impact on wildlife, but we’re not going to solve the problem by demonizing them and culling them by the millions.

The Literary Hub story starts off with a provocative question: what if cats ruled the world?

This is a question I find amusing to ponder, so instantly my mind was filled with images of cats scandalizing foreign heads of state by insouciantly swiping gifts off tables, angering diplomats by yawning and nodding off during summits, and financing the construction of massive and unnecessary coastal walls, on the off chance the ocean decides to move inland and get them wet.

Then the writer cited the repeatedly-debunked “study” that credulous media of all stripes still reference without bothering to read the text — that infamous 2013 Nature Communications paper, published by birders who author books with titles like “Cat Wars: The Consequences Of A Cuddly Killer.”

Some journalists don’t know any better, some are overworked, and some are frankly too lazy to read the study with a critical eye, but I think one of the more likely reasons people continue to cite the paper is because it’s easier to blame felinekind for wildlife extirpation than it is to admit we’re the primary culprits. After all, according to the WWF’s most recent annual review, we’ve killed off 73 percent of Earth’s wildlife since 1970, and we certainly didn’t need house cats to help us push elephants, rhinos, every species of higher non-human primate, and innumerable other species to the brink of extinction.

We did that. We did it with our relentless development, consuming and fracturing wild habitats. We did it with careless industrialization, by dumping chemicals and garbage into our rivers and lakes until more than half of them were rendered too polluted to swim in or drink from. We did it by bulldozing old growth forest and jungle, by exploiting species for fur, folk medicine, ivory, sport hunting and in the illegal wildlife trade.

More than 47,000 species — that we know of — are headed toward extinction. It’s so much easier to blame it on anyone or anything else than admit we need to make major changes to our lifestyles and policies.

But don’t take my word for it. Here’s what Alley Cat Allies has to say about the 2013 meta-analysis and its derivative papers:

The Smithsonian-funded study published in Nature Communications is not rigorous science.
It is a literature review that surveys a variety of unrelated, older studies and concocts a highly speculative conclusion that suits the researchers’ seemingly desperate anti-cat agenda. This speculative research is highly dangerous. It is being used by opponents of outdoor cats and Trap-Neuter-Return (including the authors) to further an agenda to kill more cats and roll back decades of progress on TNR. And it is being spread unchecked by the media.

Here’s what a group of ethicists and anthropologists wrote about the claims against cats in the journal Conservation Biology, lamenting the lack of nuance and danger in arguing that cats must be stopped “by any means necessary.” The drive to blame felines, they argue, has “fueled an unwarranted moral panic over cats”:

“Contrary to Loss and Marra’s claims that the scientific consensus is consistent with their views that cats are a global threat to biodiversity, the actual scientific consensus is that cats can, in certain contexts, have suppressive population-level effects on some other species (Twardek et al. 2017). This is something that is true of all predators, native or not (Wallach et al. 2010). Thus, cats should not be profiled as a general threat a priori and without reference to important factors of ecological context, situational factors, clear definition of harms, and evidence thereof.”

“There are there are serious reasons to suspect the reliability of the new, extreme cat-killer statistics,” wrote Barbara J. King, retired chairwoman of the department of anthropology at The College of William and Mary.

Like we’ve often noted here on PITB, the authors of the Nature Communications study can’t even say how many free-ranging felines exist in the US. They say it’s between 20 and 120 million. That’s a 100 million difference in the potential cat population! How can they tell us how many birds and mammals are killed by cats if they can’t even tell us how many cats there are? No amount of massaging the numbers can provide an accurate picture if the initial data is shaky or nonexistent.

Furthermore, the nature of a meta-analysis means the authors depend on earlier studies for estimates on predatory impact, but the 2013 Nature Communications paper does not include any data —not a single study — on feline predatory impact. In other words, they have no idea how many animals free-ranging cats actually kill.

In authentic studies that actually do measure predatory impact, the data varies widely in geographic and demographic context. Data derived from the D.C. Cat Count, for example, shows that cats living more than 800 feet from forested areas rarely kill wildlife, and are much more likely to kill rodents.

Those who cite the bunk study and its derivatives are “demonizing cats with shaky statistics,” King wrote, adding she was alarmed by “an unsettling degree of uncertainty in the study’s key numbers.”

Ultimately, we agree with Wayne Pacelle, former president of the Humane Society of the United States.

The meta-analysis authors “have thrown out a provocative number for cat predation totals, and their piece has been published in a highly credible publication, but they admit the study has many deficiencies. We don’t quarrel with the conclusion that the impact is big, but the numbers are informed guesswork.”

Cats do have a negative impact on wildlife, it varies according to local circumstances, and those of us who love cats have a responsibility to keep our pets indoors and help manage free-ranging populations.

But cooler heads must prevail, approaches to managing cats must be evidence-based, and the effort requires people of all kinds working together — which becomes much more difficult when agenda-driven pseudoacademics whip people into a frenzy by portraying felines as bloodthirsty, invasive monsters who need to be wiped out “by any means necessary.”

When that kind of rhetoric drives public policy, you get countries like Australia killing two million cats by air-dropping poisoned sausages, vigilantes gunning down cats with shotguns in public parks, and local governments offering cash prizes to children who shoot the most cats and kittens. Those efforts aren’t just cruel and inhuman, there’s not a shred of proof that they do a damn thing to help other species.

Solving the problem of free-ranging cats requires us to own up to our own role in species extinction and to take measured, evidence-based steps to protect vulnerable wildlife. Otherwise, we’re inflicting a whole lot of suffering on sentient creatures and accomplishing absolutely nothing.

Amazing Cats: The Sunda Clouded Leopard

This singular species of wildcat exists only on two islands and has evolved to live a semi-arboreal existence deep in the jungle.

While tigers, lions and domestic cats are the stars of the felid world and command the lion’s share (pun intended) of the attention, even from cat lovers, there are obscure species living in far-off locations where they’re rarely glimpsed by human eyes.

There’s the fishing cat, the black-footed cat and the sand cat, and then there are species that are obscure even among the obscure. The Sunda clouded leopard fits into that category, inasmuch as the unique felid can fit into any category.

Like orangutans, the Sunda clouded leopard can be found in only two places in the world: the Indonesian islands of Borneo and Sumatra. They’re faced with the same existential threat that has pushed orangutans dangerously close to extinction, which is the relentless destruction of old-growth jungle to clear land for more palm oil plantations.

Palm oil is coveted by multinational corporations in the food and cosmetics businesses, and it’s in everything from chocolate and instant noodles to lipstick and margarine, according to the World Wildlife Fund.

The problem with razing old growth jungle and forest is that it doesn’t just grow back. They’re extremely delicate ecosystems that have arrived at a natural balance over thousands of years, with every species of animal and plant contributing something vital to the vibrant tapestry of life the jungles host and support. You can’t just plant trees and usher animals to a new home. It would take hundreds of years for those new jungles to even superficially resemble the lifegiving old growth jungle.

There are heartbreaking images of shocked orangutans sitting in the ruins of their former homes, with nothing but the stumps of trees and dozer-trodden vegetation as far as the eye can see.

Those are the lucky ones. The loggers who work for massive multinational corporations aren’t bound by rules or ethics, and they won’t wait for animals to clear out before they destroy.  They often shoot orangutans on sight regardless of whether the animals are carrying young.

That’s the primary reason why Borneo and Sumatra are now home to entire academies for orangutan orphans, who spend at least eight years learning how to fend for themselves with the help of specialists who teach lessons that would normally be taught by the orphan orangutans’ mothers. They include the very basics, like how to move and climb through the jungle, as well as crucial information such as which berries to avoid while foraging.

While there’s no “academy” for clouded leopards and the felids are more adept at avoiding human wrecking crews, they’ve suffered the same fate as orangutans when it comes to dwindling jungles.

This is the situation Sunda clouded leopards find themselves in, so when a trail camera recently captured footage of a mother and her two cubs, conservationists were thrilled.

The footage comes from camera traps belonging to the Orangutan Foundation, and it’s the first time anyone’s managed to obtain video of the Bornean clouded leopards with cubs in tow. The brief video shows the little family bounding through the jungle. They quickly move past the camera, but not before one of the cubs stops to look right at it with typical kitten curiosity.

Sunda clouded leopards are extraordinary cats. Size-wise, they are firmly in the “medium size wildcat” category, with males weighing about 50 pounds. Despite that, they are members of pantherinae, the genus of big cats, having diverged from a common ancestor shared with tigers, leopards, lions and jaguars.

As further proof of their in-between status, Sunda clouded leopards can neither purr nor roar. Typically, each species of felid can do one or the other. Even the species’ scientific nomenclature, neofelis nebulosa, references its intermediate status. (If you encounter alternate taxonomy for them, it’s because the clouded leopards of Borneo and Sumatra are considered distinct subspecies.)

“Due to a different bone structure in their neck, the clouded leopard cannot roar like the larger cats, but also cannot purr because it lacks the fully ossified hyoid bone that allows small cats this ability,” the Smithsonian National Zoo’s keepers explain.

Sunda clouded leopards have several unique adaptations that allow them to thrive in arboreal environments. Their massive tails act as crucial counterweights, allowing them to traverse branches high above the ground without falling. Their paws and paw pads are specialized for gripping tree branches, and their ankles can articulate in ways other felid ankles cannot, allowing the jungle-dwelling wildcats to descend from trees head-first.

Domestic cats infamously lack this adaptation, which is why firefighters are also part-time cat rescuers, coaxing the terrified little ones down from trees, utility poles and rooftops.

The clouded leopards of Borneo and Sumatra are also undeniably cute. People have noticed, which is why one of Google’s auto-complete suggestions for Sunda clouded leopard suggests the word “pet” as an addition. It’s okay to fantasize about having a clouded leopard buddy, but in addition to the fact that they are endangered, they’re also wild animals.

Consider the fact that across the estimated 200,000 years of our species’ existence, homo sapiens have domesticated precisely one felid species, and even that’s not entirely accurate. Felis catus played just as much of a role — and arguably more — than humans did in their own domestication. As predators and obligate carnivores, they are unique among domestic animals, and it took and equally unique set of circumstances to bring cat and man together.

Instead of lamenting the fact that Sunda clouded leopards can’t be pets, we can admire them in the best way possible, from a distance, while helping ensure the survival of this extraordinary, distinctive species by donating to groups like Panthera, the WWF and Global Conservation.
