10 Most Important Community Cat News Stories of 2013

It’s that time of year again—time to take stock of the year’s milestones. Check out Rolling Stone’s 50 Best Albums of 2013, for example, or Fresh Air’s book, TV, movie, and music picks.

Not to be outdone, I’ve compiled a list of what I see as the year’s 10 most important community cat news stories—a number of which even the most avid readers may have missed. (Indeed, I’ve blogged about only a handful.)

Suffice it to say, others will disagree with my choices. In fact, I’d be very surprised if anybody agreed with the entire list.

That’s fine. Better than fine, actually—if it means my selections will spark a conversation, or even a debate. Maybe even inspire others to set to work on their own list for 2014.

Without further ado, then, my picks for the 10 most important community cat news stories of 2013… Read more

Audubon Editor Suggests Poisoning Feral Cats

Armed with the recently published “killer cat study” from the Smithsonian Biological Conservation Institute and U.S. Fish and Wildlife Service, TNR opponents are calling for increasingly extreme measures.

Travis Longcore was among the first, telling KCET reporter Judy Muller that “managing and controlling unowned, free-roaming cats will require euthanasia. There are not enough shelter spaces, there is not enough sanctuary space. And we have to stand up and be honest. But the thing is something is going to die in this equation.” Witch-hunt pioneer Stanley Temple chimed in a few days later with an op-ed piece in the Orlando Sentinel in which he referred to the work of Scott Loss, Tom Will, and Peter Marra as “a new study [that] for the first time provides a science-based estimate of the number of birds and mammals killed by cats nationwide.”

A week-and-a-half later came another op-ed, this one in the Baltimore Sun and penned by American Bird Conservancy president George Fenwick, who, like Temple, endorsed the Smithsonian/USFWS paper as valid science rather than the PR scam it truly is. “Local governments need to act swiftly and decisively to gather the 30 million to 80 million unowned cats,” argued Fenwick, “aggressively seek adoptions, and establish sanctuaries for or euthanize those cats that are not adoptable.”

All of which pales in comparison to the rhetoric unleashed by Audubon magazine’s editor-at-large, Ted Williams, in his own op-ed, published in today’s Orlando Sentinel. Read more

A Great Leap Forward?

Just four years after Beijing’s brutal roundup of the city’s cats—feral, stray, and pets alike—in preparation for the 2008 Olympic Games, the number of cats on the streets is once again raising concerns. “Somewhere between 500,000 and 5 million feral cats are skulking through its courtyard houses, construction sites, and gated apartment complexes, braving the city’s bitter cold winters and raging traffic,” writes Debra Bruno on The Atlantic’s Cities blog. “Their lives are nasty, brutish, and short.”

“And in a densely populated city like Beijing, the rise in the number of feral cat colonies is not especially welcome. The cats’ nighttime howls keep people awake. They smell. They prey on the Asian magpie and the Siberian weasel, sometimes known as the ‘hutong weasel,’ a ferret-like creature that looks a little like a cute red panda. The cats tend to prefer a perch on the BMWs of the city’s nouveau riche.”

Bruno’s population “estimate” strikes me as little more than a misinformed guess—about as credible as her observation that these cats prefer Beemers. (Commenter Jessica Rapp, who lives in Beijing, isn’t buying the numbers either.) In a February, 2008 story, The Times suggested there were “at least 200,000” unowned cats in the city, citing as its source the Capital Animal Welfare Association, a Beijing-based partner of Humane Society International. [1] Bruno’s credibility is further eroded when she refers to Mother Jones’ “Faster, Pussycat! Kill! Kill!” as if it lived up to the magazine’s commitment to “smart, fearless journalism.”

On the other hand, Bruno’s exactly right when she writes: “groups like the Audubon Society claim that TNR has not proven to be effective in eliminating the population of feral cats anywhere.” (The claim itself, of course, is both factually incorrect and highly misleading.)

The timing here is interesting, though. In January, Bob Sallinger, conservation director of the Audubon Society of Portland—who attracted national attention when he began working with local TNR groups—told the Portland Tribune: “I don’t think rounding up feral cats and killing them is going to solve it better.”

But, back to Beijing’s cats…

Actual Nasty, Brutal, Short Lives
According to CNN.com, Beijing’s animal welfare activists had hoped the Olympic Games would be “a perfect catalyst in expanding animal rights.” Instead, “the authorities… stepped up their campaigns against animals—pets and strays alike—aimed at ‘cleaning up’ the city for the Games.” [2] Among the numerous horrific reports was an instance of 30 cats—90 percent of which were sterilized—being sealed in a “basement with cement because of health and safety concerns during the Games.” [2]

In its investigation of Beijing’s pre-Olympics “clean-up,” the UK’s Daily Mail reported:

“Thousands of pet cats in Beijing are being abandoned by their owners and sent to die in secretive government pounds as China mounts an aggressive drive to clean up the capital in preparation for the Olympic Games. Hundreds of cats a day are being rounded and crammed into cages so small they cannot even turn around. Then they are trucked to what animal welfare groups describe as death camps on the edges of the city. The cull comes in the wake of a government campaign warning of the diseases cats carry and ordering residents to help clear the streets of them.”

When the Daily Mail tried to visit two of the holding facilities, they were refused entry.

“‘No one can come in without official papers,’ staff shouted from behind padlocked steel gates. At another, larger compound in Da Niu Fang village, the sound of cats wailing could be clearly heard coming from a cluster of tin-roofed sheds, but workers denied they were holding any cats. ‘There are no cats here, go away. No one is allowed inside unless you have official permission,’ a security guard said.”

Apparently, the fear among the public bordered on—indeed, in some cases, turned into—hysteria. “The most striking illustration of the city-wide fear of cats,” reports the Daily Mail’s Simon Perry, took place at a kindergarten, where six strays, including two pregnant females, “were beaten to death with sticks by teachers.”

“We did it out of love for the children,” explained one teacher. “We were worried the cats might harm them. These six cats had been hanging around the kindergarten looking for food.” [3]

TNR Comes to Beijing
These days, however, some in Beijing are adopting TNR—and pushing for others to do the same. “Peng, a Chinese-American native New Yorker who has lived in Beijing for the last 20 years,” writes Bruno, “has taken on the mission of convincing Beijing’s residents that [TNR is] the best solution to the feral cat population.”

“‘What are my alternatives?’ asks Peng. As Beijing itself learned in the recent past, she argues, cities that try to exterminate cats often just find that a new cat colony eventually moves into an area where an old one had been taken away. Not to mention, the mass killing of adorable kittens is a tough sell in any society.”

While Bruno suggests that Peng’s efforts are “a drop in the bucket,” I see things rather differently. Indeed, given the recent population increase, Beijing may be the best argument yet for TNR. After all, the alternative has been shown to be remarkably ineffective. Costly, too, I’m sure.

One wonders how the lessons learned in Beijing will be “interpreted” here in the U.S.—where The Wildlife Society, American Bird Conservancy, and U.S. Fish and Wildlife Service, among others, continue to oppose TNR, in favor of the roundup of stray, abandoned, and feral cats.

Too much will, I fear, be lost in translation.

Devolution In the Classroom: Three Editions of F. Gill’s “Ornithology”

For more than 20 years now, Gill’s classic text has been required reading for ornithology students. While the book’s attention to conservation issues has expanded over its three editions, its treatment of the impact of cats on bird populations reflects an unsettling shift away from science.

The hoards of students descending upon college campuses this fall will—despite the rise of the eco-friendly PDF and a great variety of online content—more often than not find their arms and backpacks stuffed with old-school printed-and-bound books. Among them will be Frank Gill’s Ornithology, a regular offering on campus bookstore shelves for 21 years now.

Gill’s Ornithology is, I’m told by one Vox Felina reader, “considered (at least in these parts) the text regarding ornithology.” From what I can tell, it’s popularity as required reading for third- and fourth-year undergraduates isn’t limited to any one region of the country. Indeed, according to Amazon.com, the book is “the classic text for the undergraduate ornithology course.” Its third edition, published in 2007, “maintains the scope and expertise that made the book so popular while incorporating a tremendous amount of new research.”

Unfortunately, none of this new research made it into the section—a single paragraph—meant to address the “threat” of cats. Indeed, students interested in this topic are better off with the first edition, published 17 years earlier.

First Edition
“The numbers of deaths attributable directly or indirectly to human actions each year during the 1970s are staggering,” writes Gill in the 1990 edition of Ornithology, “but are apparently minor in relation to the population level.” [1] Citing a 1979 U.S. Fish and Wildlife Service report by Richard C. Banks, Gill continues:

“Human activities are responsible for roughly 270 million bird deaths every year in the continental United States. This seemingly huge number is less than two percent of the 10 to 20 billion birds that inhabit the continental United States and appears to have no serious effect on the viability of any of the populations themselves, unlike human destruction of breeding habitat and interference with reproduction… Miscellaneous accidents such as impact with golf balls, electrocution by transmission lines, and cat predation, may amount to 3.5 million deaths a year.” [1]

Predation by cats (included under “All Other Indirect”), then, according to Banks, represents about 1.3 percent of overall human-caused mortality—a loss of, at most, 0.04 percent of the U.S. bird population annually. By contrast, hunting and “collision with man-made objects” combine to make up “about 90 percent of the avian mortality documented” in Banks’ report. [2]

Second Edition
Five years later, in the second edition, the story changes dramatically. Gill discards Banks’ reference to cats and uses his 270 million figure purely for dramatic effect—the set-up for a punch line in the form of Rich Stallcup’s back-of-the-envelope guesswork (which Stallcup himself considered “probably a low estimate” [3]). Gill even includes a bar chart to drive the point home. (Apparently, he didn’t find Banks’ pie chart compelling enough to include in the his first edition of Ornithology.)

“Human activities are directly responsible for roughly 270 million bird deaths every year in the continental United States, about 2 percent of the 10 to 20 billion birds that inhabit the continental United States (Banks 1979)… Dwarfing these losses are those attributable to predation by pets. Domesticated cats in North America may kill 4 million songbirds every day, or perhaps over a billion birds each year (Stallcup 1991). Millions of hungrier, feral (wild) cats add to this toll, which is not included in the estimate of 270 million bird deaths each year.” [4]

But Stallcup’s “estimate”—published in the Observer, a publication of the Point Reyes Bird Observatory (which Stallcup co-founded)—lacks even the slightest scientific justification. In fact, “A Reversible Catastrophe” is little more than Stallcup’s advice—at once both folksy and sinister—about defending one’s garden from neighborhood cats (“…try a B-B or pellet gun. There is no need to kill or shoot toward the head, but a good sting on the rump seems memorable for most felines, and they seldom return for a third experience.” [3]).

“Let’s do a quick calculation, starting with numbers of pet cats. Population estimates of domestic house cats in the contiguous United States vary somewhat, but most agree the figure is between 50 and 60 million. On 3 March 1990, the San Francisco Chronicle gave the number as 57.9 million, ‘up 19 percent since 1984.’ For this assessment, let’s use 55 million.

“Some of these (maybe 10 percent) never go outside, and maybe another 10 percent are too old or too slow to catch anything. That leaves 44 million domestic cats hunting in gardens, marshes, fields, thickets, empty lots, and forests.

“It is impossible to know how many of those actively hunting animals catch how many birds, but the numbers are high. To be very conservative, say that only one in ten of those cats kills only one bird a day. This would yield a daily toll of 4.4 million songbirds!! Shocking, but true—and probably a low estimate (e.g., many cats get multiple birds a day).” [3]

It’s hardly surprising that Stallcup’s “estimate” grossly exaggerates predation rates since his research never went any further than the Chronicle’s mention of the U.S. pet cat population. His assumptions about how many of these cats go outdoors and their success as hunters stand in stark contrast to the trend suggested by pet owner survey results and various predation studies (some of which suggest that just 36–56 per­cent of cats are hunters. [5, 6])

(It was, no doubt, the “shocking” aspect of Stallcup’s numbers that appealed to Nico Dauphine, who, in her “Apocalypse Meow” presentation, acknowledges that Stallcup “didn’t do a study” but nevertheless concludes, inexplicably, that his “is a conservative estimate.”)

Unnatural Selection
So, how did Stallcup’s indefensible “estimate” make it into the standard ornithology textbook? It was, Gill told me recently by e-mail, “one of the few refs [he] could find.”

Referring to what he calls “the great cat debates,” Gill writes: “I claim no great expertise or authority… now or in the ancient histories of early textbook editions.”

Fair enough. Writing, editing, and revising multiple editions of Ornithology was an enormous undertaking—one for which Gill deserves much credit. But there was, available at the time, work by scientists who, unlike Stallcup actually studied predation. Indeed, even before the first edition of Ornithology was published, a great deal of work had been done—and compiled in the first edition (published in 1988) of The Domestic Cat: The Biology of Its Behaviour. In it, Mike Fitzgerald, one of the world’s foremost experts on the subject, reviewed 61 predation studies, concluding:

“Predation on songbirds by domestic cats is noticed because it takes place during the day, whereas much predation on mammals takes place at night. People generally enjoy having songbirds in their gardens, and providing food in winter may increase the numbers of birds. When cats kill some of these birds, people assume that cats are reducing the bird populations. However, although this predation is so visible, and unpopular, remarkably little attempt has been made to assess its impact on populations of songbirds.” [7]

Two years later, Fitzgerald had a brief letter on the subject published in Environmental Conservation. His comments are as relevant today as they were some 21 years ago:

“Before embarking… on programmes to educate the public so that they will pressure elected officials to act on ‘cat delinquency,’ we must discover what effect domestic cats really have on the wildlife populations in various urban localities—not merely what effect we assume they have on the basis of prey brought home by cats in one English village. Although we know what prey cats bring home in a few urban localities, we do not know what effect this predation has on the prey populations, or how the wildlife populations might differ if cat populations were reduced. Until we have this information we cannot ensure sound educational programmes. We should perhaps also try to discover what values urban people place on their wildlife and their pets—it seems likely that many of the people who love their pets also treasure the wildlife.” [8]

Surely, Fitzgerald’s work would have been more appropriate for, and useful to, Ornithology’s audience. Instead, unsuspecting undergraduates were treated to biased editorializing dressed up as science.

Third Edition
Gill tells me I wasn’t the first to “react… to the Stallcup paper,” and that the push-back was sufficient to prompt its removal from the third edition. Gone, too, is Banks’ report. Instead, Gill employs the now-common kitchen-sink approach, rattling off a litany of sins—borrowed, it seems, from the American Bird Conservancy.

“Domestic house cats in North America, for example, may kill hundreds of millions of songbirds each year. Farmland and barnyard cats kill roughly 39 million birds (and lots of mice, too) each year. Millions of hungrier, feral (wild) cats add to this toll. There is a common-sense solution. Letting cats roam outside the house shortens their expected life span from 12.5 years to 2.5 years and increases their risk of rabies, distemper, toxoplasmosis, and parasites. Evidence is mounting that cats help to spread diseases such as Asian bird flu. The message is clear: Keep pet cats inside for their own well being and for the future of backyard birds (http://www.abcbirds.org/cats/).” [9]

That 39 million birds figure, of course, comes from the infamous “Wisconsin Study,” the authors of which claim: “The most reasonable estimates indicate that 39 million birds are killed in the state each year.” [10] (The “reason” is, in fact, notably absent from Coleman and Temple’s figure—which can be traced to “a single free-ranging Siamese cat” that frequented a rural residential property in New Kent County, Virginia. [11])

Its implied use as a nationwide estimate, Gill says, was “a lapse.” The more serious lapse by far, though—not in copyediting but in judgment—is Gill’s endorsement of ABC.

A Constructive Approach
While he readily admits that he’s “not tracked nor verified [ABC’s] stats (and have paid precious little attention to the issue for almost 10 years),” Gill’s support is unwavering.

“ABC has taken a lead role on the cat-bird issues, generally with a constructive approach, which I applaud, given how polarized the debates can be.”

Constructive? As I’ve pointed out repeatedly, no organization has been more effective at working the anti-TNR pseudoscience into a message neatly packaged for the mainstream media, and eventual consumption by the general public. (The Wildlife Society, though, which shares ABC’s penchant for bumper-sticker science and public discourse via sound-bites, is at least as eager to participate in the witch-hunt.)

Among the more glaring examples: senior policy advisor, Steve Holmer’s claim, quoted in the Los Angeles Times, that “there are about… 160 million feral cats [nationwide]” [12]; ABC’s promotion of “Feral Cats and Their Management,” with its absurd $17B economic impact “estimate,” published last year by the University of Nebraska-Lincoln; and the numerous errors, exaggerations, and misrepresentations that persist in their brochure Domestic Cat Predation On Birds and Other Wildlife (PDF)—including a rather significant blunder that Ellen Perry Berkeley brought to light seven years ago in her book TNR Past, Present and Future. [13]

A constructive approach begins, by necessity, with sound science. But when it comes to the issue of free-roaming cats, at least, ABC has demonstrated neither an interest nor an aptitude.

So how does such an organization end up as the sole resource listed in a widely-used undergraduate textbook? (One written by the same man who served as the National Audubon Society’s chief scientist from 1996 to 2005, no less.) What’s next—physiology and nutrition books directing students to the PepsiCo Website for their hydration lesson? Psychology texts deferring to Pfizer (makers of Zoloft) on selective serotonin reuptake inhibitors?

Frank Gill’s View
Gill never responded to my follow-up questions for this post. Still, his comments during our first exchange shed some light on his general attitude toward cats. “I have owned some wonderful (Siamese) cats in my life,” Gill explained, “so I do view them positively in many ways. But when they are dumped near a research station by returning vacationers and then eat the ringed birds I have been studying for many years, I take a different view.”

He followed this last sentence with a smiley-face emoticon, though the joke was clearly wasted on me.

“My informal view now is that managed feral cat colonies are potentially a serious threat to local bird populations, including both migrants that stopover in urban parks and endangered shorebird colonies. Sustaining those colonies should be prohibited generally. The return of coyotes to suburban landscapes is most welcome both to add a top predator to these ecosystems and to counter the numbers of feral cats as well as other midsized predators that impact breeding productivity. Just their presence in a neighborhood should persuade cat owners to keep their cats safely inside!”

•     •     •

It would be a mistake to suggest that the sloppy, flawed research I spend so much time critiquing can be traced directly to the second or third editions of Frank Gill’s textbook. Still, for many students, the path to a degree in ornithology (and onto related graduate degrees) leads through the book of the same name. As such, Ornithology may well be their first exposure to issues of population dynamics, conservation, and the like.

First impressions tend to be lasting ones. If, as a wide-eyed undergraduate, you “learned” that cats kill up to four million songbirds every day, how might that shape your future studies? Your career? What if you “learned” that such predation takes a $17B toll on the country annually?

Considering the tremendous burden we’re placing on future generations, why would we hobble them—before they even get started, really—with such misinformation and bias? They’ve got more than enough on their plate without having to fact-check their textbooks, too.

Without Apologies

The conversation continues on Audubon magazine’s blog, The Perch, with Travis Longcore doing everything he can to dodge the straightforward question I posed: If TNR and the feeding of feral cats are outlawed, then what will become of the many, many cats no longer receiving human assistance?

Among the topics he prefers to discuss are—and I have to say, this one caught me by surprise—me. Especially my reference to him as a “great purveyor of misrepresentations and bias” on the Vox Felina Facebook page. OK, perhaps I could have worded that differently, but as I point out in my most recent reply (fourth comment, page 2), if he’s going to stand by his 2009 paper, then he really has earned the title.

In his reply to a post by Vox Felina reader Laurie G., of Stray Pet Advocacy, Longcore lays out a litany of complaints against me:

“Peter Wolf has been attacking scientists with demeaning generalizations and grossly inflammatory statements on his blog for months now. He can also be clever and I appreciate the exchange we’re having on this page, but he accuses scientists of being grossly in competent and corrupt on a regular basis (bordering on slander) so I’m not going to apologize for being critical of him. Given the level of rhetoric on his blog and his vox felina persona on FB directed at me, this [is] a comparatively civil discussion.”

I don’t know about “bordering on slander.” I try to keep my criticisms focused on specific aspects of specific studies, reports, reviews, etc. And I go out of my way not to make hasty generalizations. As for all the rest: guilty.

Meanwhile, over at The Wildlife Society blog, Making Tracks, my comment (asking Executive Director/CEO Michael Hutchins the same question I posed to Longcore) has yet to be approved despite repeated attempts on my end. Apparently, my last exchange with Hutchins was…. well, my last exchange.

Conversation Killer

Over the weekend, a comment (criticizing, once again, the recently released University of Nebraska-Lincoln “report”) I posted on Audubon magazine’s blog, The Perch, drew fire from Travis Longcore.

Longcore, of course, is the lead author of the widely circulated paper, “Critical Assessment of Claims Regarding Management of Feral Cats by Trap-Neuter-Return” and Science Director for the Urban Wildlands Group, the lead plaintiff in the case that led to the TNR-related injunction in Los Angeles earlier this year (under which City-funded spay/neuter vouchers for feral cats and shelter-based TNR promotions have been halted; TNR, however, continues), a decision currently making its way through the appeal process (I heard just this afternoon that “Round 2” was decided in favor of the plaintiffs).

After a weekend of back-and-forth debate about the science surrounding the UNL report and, more broadly, feral cats and TNR, I posed the following question to Longcore:

You’ve been very straightforward about your desire to see TNR and the feeding of feral cats outlawed. But then what?

I’ve yet to hear from you—or anybody on your side of the issue—spell it out. We all know the cats won’t disappear in the absence of TNR/feeding. We can argue about rates of population growth, carrying capacity, etc.—but let’s keep it simple here. Under your plan, there are these feral cats—an awful lot of them—that no longer have access to the assistance of humans (other than scavenging trash, say). OK, now what?

Will it be like what was done on Marion Island, where—despite being only 115-square-miles in size, barren, and uninhabited—it took something like 16 years to eradicate 2,500 cats? Using disease (feline distemper), poisoning, intensive hunting and trapping, and—if I’m not mistaken—dogs.

And, while we’re at it, who will pay for this unprecedented nightmare?

These are not rhetorical questions. As I say, I’ve heard plenty of arguments against TNR over the past year or so. I’ve yet to hear a single counter-proposal. Not one.

Trap-and-remove? That’s not a proposal—that’s a bromide. I want to hear about how all this would play out. And this seems like an appropriate venue, given the original topic and your role in the L.A. injunction.

So, Travis, what would you do?

Two days later, no word from Longcore. a well-considered reply, but still no answer to the question posed.

Repeat After Me

Listening to NPR’s On the Media this weekend, I was struck by a story (first broadcast in 2006) about how certain “sticky” numbers—however dubious—find their way into the media landscape and beyond, as On the Media co-host Brooke Gladstone noted:

“Four years ago, we delved into the mysterious number, said to be 50,000, of child predators online at any given time. It was cited by the NBC Dateline program “To Catch a Predator” and also by then Attorney General Alberto Gonzales.

But spokespersons for the FBI, the National Center for Missing and Exploited Children, and the Crimes against Children Research Center said it was not based on any research they were aware of. The A.G.’s office at the time, well, they said it came from Dateline.”

Wall Street Journal columnist Carl Bialik, who spoke to Gladstone for the story, described the process whereby such slippery figures gain traction:

“An interesting phenomenon of these numbers is that they’ll often be cited to an agency or some government body, and then a study will pick it up, and then the press will repeat it from that study. And then once it appears in the press, public officials will repeat it again, and now it’s become an official number.”

All of which sounds very familiar—Bialik could easily be describing the “official numbers” put out by so many TNR opponents. Among those that have gained the most currency are the predation estimates from the Wisconsin Study, the American Bird Conservancy’s figure for the proportion of birds in the diets of free-roaming cats, and Dauphiné and Cooper’s estimate of free-roaming cats in the U.S.

The Wisconsin Study
Despite its having been discredited long ago (see, for example, “Addressing the Wisconsin Study”), the Wisconsin Study continues to be cited as if its estimate of 8–219 million birds killed by the state’s rural cats [1] was credible. As recently as last year, Longcore et al. cited the work in their essay “Critical Assessment of Claims Regarding Management of Feral Cats by Trap–Neuter–Return.” [2]

This, despite the fact that—15 years earlier—co-author Stanley Temple told the press:

“The media has had a field day with this since we started. Those figures were from our proposal. They aren’t actual data; that was just our projection to show how bad it might be.” [3]

It’s true: the media has had a field day. Among the major newspapers to cite the Wisconsin Study are the Wall Street Journal [4], the New York Times [5], and the Los Angeles Times [6]. However, as I’ve described previously, it’s been the wildlife conservationists and bird advocates who’ve really had a field day with the Wisconsin Study:

  • The American Bird Conservancy (ABC) refers to the study, in its brochure Domestic Cat Predation on Birds and Other Wildlife. And the ABC goes one step further, pointing out that Coleman and Temple’s estimate was for rural cats, and that “suburban and urban cats add to that toll.” [7]
  • A 2009 article in Audubon Magazine suggests “cats were annually knocking off somewhere in the neighborhood of 8 million birds just in rural Wisconsin.” [9] To the magazine’s credit, they used Coleman and Temple’s low estimate—but none of the numbers from the Wisconsin Study are scientifically sound.

Birds Represent 20–30% of the Diet of Free-roaming Cats
According to an ABC report (downloadable from their website), “extensive studies of the feeding habits of domestic, free-roaming cats… show that approximately… 20 to 30 percent [of their diet] are birds.”

This, apparently, is the same report that Ellen Perry Berkeley debunked in her book, TNR Past Present and Future: A history of the trap-neuter-return movement, noting that the ABC’s 20–30% figure was not based on “extensive studies” at all. [10] In fact, just three sources were used: the now-classic “English Village” study by Churcher and Lawton [11], the Wisconsin Study (described above), and Mike Fitzgerald’s contribution to “The Domestic Cat: The Biology of Its Behaviour.” [12]

This gets a little complicated, so bear with me.

When Churcher and Lawton reported, “overall, birds comprised 35% of the total catch,” [11] they were referring to prey tallies recorded by study participants—not to the overall diets of the cats involved. Figures obtained through similar methods for the Wisconsin Study were 20–23%, [1, 13, 14] which the authors suggest—citing Fitzgerald’s comprehensive review of predation and dietary studies—are in line with other work:

“Extensive studies of the feeding habits of free-ranging domestic cats over 50 years and four continents [12] indicate that small mammals make up approximately 70% of these cats’ prey while birds make up about 20%.” [14]

But they’re comparing apples and oranges. Both the English Village and Wisconsin Studies report the percentage of birds returned as a portion of the “total catch,” whereas Fitzgerald reports percentage by frequency (i.e., the occurrence of birds in the stomach contents or scats of free-roaming cats), a point apparently lost on Coleman and Craven. The 21% figure [12] they refer to, then, is simply not comparable to their own (or that of the English Village study, a fact Churcher and Lawton acknowledge in their paper). As Berkeley notes, “this would put birds, as a portion of the diet of cats, at roughly 7 to 10.5 percent—nowhere near the ‘20 to 30 percent’ figures unleashed on the unscientific public by ABC!”

To put all of this into more familiar terms, it’s a bit like saying that coffee makes up 20–30% of the American diet versus saying that 20–30% of Americans drink coffee each day.

Nevertheless, 13 years after the ABC first published its report, the myth persists. The report—including the mistaken dietary figures—is still available. And the National Audubon Society has helped perpetuate the error, noting in its Resolution Regarding Control and Management of Feral and Free-Ranging Domestic Cats:

“…it has been estimated that birds represent 20–30% of the prey of feral and free-ranging domestic cats.”

Estimates of Free-roaming Cats
In January, Steve Holmer, the ABC’s Senior Policy Advisor, told the Los Angeles Times, “The latest estimates are that there are about . . . 160 million feral cats [nationwide].” Sounds like an awful lot of cats—nearly one for every two humans in the country. So where does this figure come from?

The source is a paper by Nico Dauphiné and Robert Cooper (which can be downloaded via the ABC website), presented at the Fourth International Partners in Flight conference. In it, Dauphiné and Cooper use some remarkably creative accounting, beginning with an unsubstantiated estimate of unowned cats, to which they add an inflated number of owned cats that spend time outdoors. In the end, they conclude that there are “117–157 million free-ranging cats in the United States.” [15] (For a more thorough explanation, see my previous post on the subject.)

Estimating the number of free-roaming cats wasn’t even the point of their paper. As the title—“Impacts of Free-ranging Domestic Cats (Felis catus) On Birds In the United States: A Review of Recent Research with Conservation and Management Recommendations”—suggests, the primary purpose was to describe the cats’ impact on birds. The authors’ exaggerated figure was merely a convenient route to their estimate of birds killed annually by cats: “a minimum of one billion birds” [15] (which, it should be clear, has the potential to become a very sticky number).

Holmer goes a step further, using only the upper limit of the range published by Dauphiné and Cooper, and making the subtle—but important—shift from free-ranging to feral cats.

When I asked him about this, he explained that those figures were “based on an earlier version of Nico’s latest paper and are now being updated in our materials.” I don’t know that any such changes were made; and in any event, the bogus estimate has already been published in the L.A. Times—as if it were true.

TNR opponents will often point to the vast collection of research studies, government reports, news accounts, and the like, that support their assertions. Drill down a bit into that collection, though, and they all start to look alike: the same familiar sources, the same flawed studies—and the same bogus figures. These figures have become the kind of “official numbers” Bialik refers to: quantitative poseurs owing their popularity to tireless—and irresponsible—repetition more than anything else.

The Things People Say (or Don’t)—Part 2

Like the Urban Wildlands Group, the Los Angeles Audubon Society seems eager to spread the word about the “threat” of feral cats. But, just like Urban Wildlands Group, what they’re saying doesn’t always add up.

The L.A. Audubon Society was (along with the Urban Wildlands Group) a petitioner in the case (LASC BS115483) that eventually led to an injunction against publicly supported TNR in Los Angeles. So it was no surprise to see a representative quoted in the Los Angeles Times:

“At San Pedro’s Cabrillo Beach, a feral cat colony resides near where snowy plovers nest, said Garry George, conservation chairman for the Los Angeles Audubon Society. At San Francisco’s Golden Gate Park, George said, feral cats have wiped out the California quail population. And in San Diego, feral cats roam free near a habitat for the California least tern, which officials are trying to monitor and protect, he said.”

I’ve yet to look into George’s claims—and will reserve judgment until I have. That said, I think there’s reason to be wary. In February 2009, George had an article published in the online version of Los Angeles Magazine that raises questions about his ability to serve as a trustworthy spokesperson on the subject of feral cats. In “How to Make Your Yard a Bird Magnet,” George writes:

If feral cats are destroying your property, including your birds, you can use a Hav-a-Heart trap with a permit from Animal Services. They will spay or neuter the cats you trap and offer to find them a home.

To start with, it’s not clear that George’s bit of advice (including a link taking readers to the American Bird Conservancy’s Cats Indoors! campaign, a topic all its own) belongs in the article all. Then there’s his choice of words (to hear George tell it, you’d think real estate values in L.A. would be suffering for all the destruction wrought by feral cats!).

The real issue, though, is George’s assertion that L.A. Animal Services will sterilize and help find homes for the feral cats you trap. I’ve spoken with a representative at L.A. Animal Services, and was told—in no uncertain terms—that this is simply not the case. And it wasn’t true when George wrote it, either.

It’s hardly surprising—given how overcrowded L.A.’s shelters are with adoptable cats—that they’re not offering to find homes for feral cats (which often make for “difficult” adoption candidates). For George to suggest that these cats were headed for a happy ending is highly irresponsible. Either he didn’t know any better, or he intended his statement to be misleading and deceptive (he failed to respond to my inquiries on the subject). In either case, George had no business writing what he did. The fact that he did write it raises unsettling questions about his integrity and that of the organization he represents.

All of which begs another rather unsettling question: Do supporters of the L.A. Audubon Society fully understand what they’re supporting?
