Cats May Be Able To Help Detectives Solve Crimes

An Australian team decided to look for DNA evidence in a novel place: cat fur. Their findings could give law enforcement a powerful new tool to identify crime suspects.

When you think of a crime scene, you probably picture uniformed officers manning the perimeter, crime scene tape cordoning off the room where the deed was done, detectives trying to reconstruct what happened, and techs collecting evidence.

Those techs might swab surfaces for traces of a suspect. Drinking cups and water bottles might be dusted for fingerprints, stray hair might be bagged and sent back to the laboratory for analysis. Discarded cigarette butts, door handles, buzzers — they can all yield evidence, to say nothing of cell phones, USB sticks and smart appliances.

But what about the pets? If a suspect was especially careful not to leave prints or touch anything at the crime scene, could the fur of a cat harbor DNA?

A team comprised of scientists from Australia’s College of Science and Engineering at Flinders and the Victoria Police Forensic Services Department wanted to know if cat fur could indeed hold critical evidence at crime scenes, so they conducted a study involving 20 pet cats from different homes, and what they found could provide an important tool for law enforcement. Their findings were published in the journal Forensic Science International.

If detectives are trying to piece together the identities of robbers who, say, broke into a home, brutalized the people there at gunpoint and stole their valuables, they can’t interview the victims’ pet cats about what they saw, but it turns out they can swab the kitties’ fur and have an excellent chance of retrieving useful DNA.

Blacksad is a famous feline detective in his own series of comic books. He may have to be careful not to leave his stray fur all over his own crime scenes.

The research team swabbed the fur of pet cats in their test households, took DNA samples of the adults living in those homes — who were the stand-ins for victims — and asked the human participants to fill out surveys asking about their cats, what they do on a typical day, and whether or not they have interaction with people outside the home.

After the team conducted DNA analysis on the fur swabs “[d]etectable levels of DNA were found in 80% of the samples and interpretable profiles that could be linked to a person of interest were generated in 70% of the cats tested,” the study authors wrote.

While most of the samples matched the DNA of people who lived in the homes — as expected — samples from six cats revealed the presence of DNA from other people. The research team didn’t take DNA samples of minors, and two of the positive fur swab samples came from cats who lived in a home with a child and slept in that child’s bed most evenings. But four other samples turned up “mystery” DNA even though no one else had visited those homes for at least several days.

For DNA from pets to have any real evidentiary value, prosecutors have to prove a “chain of custody” of sorts, establishing that suspects could not have had contact with the animals in question unless they were inside a home where a crime has taken place. If the cat is allowed to roam outdoors every day, for example, it becomes much more difficult to prove a suspect’s DNA was transferred to a pet inside a home rather than on the street.

That’s why the research team is hopeful, but also cautions that their study is a first step toward understanding more about how human DNA is transferred to fur, whether it requires a person to be physically present (as opposed to their DNA being passed along secondhand in stray hair or skin cells), how long a cat’s fur can harbor human DNA, and other questions prosecutors will have to answer.

“This type of data can help us understand the meaning of the DNA results obtained, especially if there is a match to a person of interest,” said study co-author Mariya Goray, a DNA transfer expert. “Are these DNA finding a result of a criminal activity or could they have been transferred and deposited at the scene via a pet?”

The team recommends more research “on the transfer, persistence and prevalence of human DNA to and from cats and other pet animals and the influences animal behavioral habits, the DNA shedder status of the owners and many other relevant factors.”

If they do answer the aforementioned questions and prosecutors believe they can establish a suspect’s presence at a crime scene thanks to feline-provided evidence, it might not be too long before we see a cat-centric episode on future seasons of Law & Order or CSI, both of which are scheduled to be revived as police procedurals enjoy a resurgence on TV.

Must rub on person! — As dedicated cat servants know, cats rub against everything and everyone. The behavior is instinctual, and cats have pheromone glands on their faces, sides and paws, which they use to transfer their scent..and fur.

Is Your Cat In Pain? The Feline Grimace Scale Can Tell You

For the first time, veterinarians and regular cat parents have a tool that can tell them if their cats are hurting.

Although there’s been lots of talk claiming cats don’t have facial expressions humans can parse — or even the muscles to noticeably change expressions — that’s not actually true.

It’s more accurate to say feline facial expressions are far more subtle than their human or even canine equivalents, and it takes an expert — a veterinarian or behaviorist with specialized training — to accurately read them.

This is a brand new frontier for veterinary science, and it’s all thanks to the feline grimace scale, a system developed by researchers at the University of Montreal in 2019. Using video clips of cats in various moods and stages of pain or pain-free expression, the researchers built a system that could reliably determine how a cat is feeling. (You can read more about how they did that here.)

“I call it the Rosetta Stone for interpreting how a cat is feeling,” veterinarian Liz Bales says in a new video at dvm360. “It turns out that very subtle changes in cat’s facial expressions can tell us whether or not they’re in pain. It includes the position of the ears, the opening of the eyes, the expression on the mouth, how the cat is holding its whiskers, and how they’re holding their head.”

Each of the five elements of feline facial expression are scored on a three-point scale, then added up. The result provides an accurate assessment of how a cat feels.

“It’s amazing, and it allows us to interpret feline pain in a way we never could before,” Bales says. “The hard part is, it can be a little bit tricky to learn. It is learnable, but I specialize in this and I’m still struggling to get it right every single time.”

Despite the challenge, she says, it’s well worth learning.

“The applications of this are so far and wide, and I think as the technology grows and it becomes easier and easier to use the grimace scale, the more exciting it’s going to be.”

Thanks to an app named Tably, cat servants don’t have to know how to read the most subtle feline facial expressions anymore. By running a photo of your cat through the app’s algorithm, Tably can read your cat’s expression for you.

Tably Bud — Tably gauges cats’ moods in addition to their pain levels. We used the web app to evaluate Buddy last year. Thankfully he was happy!

Bales says she envisions a near future in which pet parents monitor their cats’ health and mood daily, and the scale becomes the standard for end-of-life care. With a “validated, consistent way to measure pain, we can look into more pain drugs for cats, what’s working, what isn’t.”

“A cat in pain looks like a resting cat to most people, but now we have this tool,” Bales says. “And I think as the tool evolves and we give cats a way to really speak for themselves through this Rosetta Stone of the grimace scale, then the more we understand that we can do for them, the more we’re going to do for them.”

We wrote about the feline grimace scale and Tably last year, and noted it had a lot of promise for veterinarians and us cat servants. At the time Tably was in beta and had a web app that allowed anyone to use the technology.

Unfortunately the web app seems to have disappeared, and the app is now available only to iOS users. Since we switched from an iPhone to Android, we can’t access Tably for the time being. (Let’s hope an Android version is forthcoming.) But if you have an Apple device, the app is definitely worth checking out.

Sunday Cats: Expert Fails At Feline Facts, Aussie Karen Lures Cats From Home To Issue Roaming Fine

Declawing is evil and cruel, mmmkay?

This is why we always say it’s better for cat servants to regulate themselves than allow the government to get involved.

A Karen in Australia issued a $280 fine to a homeowner for allegedly allowing his cats to roam — after she lured the kitties onto the street herself.

The entire bizarre spectacle was captured on security cameras at the home of Julie and Steven Stephens, a couple in Toowoomba, about 80 miles west of Brisbane. The uniformed Karen, who is employed by the Queensland council, totes a clipboard in one hand as she walks up the Stephens’ driveway in broad daylight.

As one of the curious cats approaches, Karen reaches for a pen in her pocket and starts scribbling on her clipboard, apparently eager to get started on the paperwork, before slowly backpeddling so the kitty will continue to follow her. When the cat reaches the sidewalk, the unnamed woman scoops it up and walks to her government-issued vehicle parked in front of the Stephens’ home.

Steven Stephens was watching the episode unfold via his camera system and bolted outside to stop the government employee from taking his cat, he told Yahoo News Australia.

The Karen wasn’t able to “impound” the cat, but she wrote Stephens a hefty fine for “allowing his cat to roam,” and promised she’d be back to inflict more misery.

“She said she would be back in two weeks with the police to take all but two of our dogs,” Mr Stephens said.

We’re unable to embed the video, but you can watch it at Yahoo News Australia.

Unbelievably, Toowoomba Regional Council “CEO” Brian Pidgeon doubled down and quoted the relevant section of law on pet roaming when a local newspaper asked him about the incident. Pidgeon did acknowledge his employee was accused of luring the Stephens’ cat, but said he couldn’t talk about that because he’s conducting an “internal investigation,” which is bureaucrat-speak for figuring a way to worm his way out of the situation. There is, after all, clear video showing the Karen luring the cat away. There is nothing ambiguous about what happened.

Stephens admitted he and his wife have “too many” dogs according to local law, which has set arbitrary limits on animal custodianship, but said there are good reasons for that. The dogs sooth his wife, he said.

“A few years ago she had a severe car accident, her partner at the time died, she has a metal plate in her head and now has severe depression and anxiety,” Stephens said. “The dogs help with her anxiety.”

The family has been so rattled by the incident, and apparently has so little faith in their local government to treat them fairly, that they told Yahoo News they’re looking to sell their home and move to “a larger parcel of land in the bush.”

That in itself is an extraordinary admission, indicating they don’t expect basic courtesy, honesty or professionalism from the local authorities.

Now imagine how this would have played out if the Stephens family did not have security cameras. The council worker would have said their cats wandered off the family’s property of their own accord, and that would have been it. The Stephens would be forced to pay the fines, have a legal battle on their hands to get their cats back, and would be fretting over the impending confiscation of their dogs.

I know I sound like a broken record with regard to how local governments, guided by bunk “research” studies, impose themselves on pet caretakers, especially those of us who have cats. That’s why it’s important not to give them any reason to interfere — and to make sure everything is recorded, as the Stephens family wisely did.

Who knows what the government Karen’s motivations were. Was she trying to meet a quota? Does she dislike animals? Does she enjoy flexing the little bit of power she has, or inflicting misery on others? By preempting legislation on cat ownership and roaming, we can avoid putting ourselves at the mercy of such people in the first place, which is in the best interest of cat caretakers, and most importantly cats themselves.

Feline fact fail

I’m sure Nigel Barber, PhD., is a nice guy. I don’t mean to give him any grief. But when you present yourself as an expert on a topic and you write an authoritative column on a trusted site that has millions of readers, you really should make sure you’re not spreading misinformation or providing a picture of a situation that is decades behind the current science.

In a column for Psychology Today titled “Does Your Cat Love You?“, Barber rattles off a list of cliches, half-truths and outright falsehoods about cats, the kind of thing you might have expected 20 or 30 years ago before a wealth of research helped us dispel incorrect assumptions about felis catus.

After mucking up the domestication timeline, Barber says cats are “fearful of people,” “tend to withdraw from strangers,” and paints an outdated picture of aloof animals who technically don’t need human care to thrive. He also says cats attack people, including their caretakers, without warning or provocation.

Then there’s this nugget:

“As essentially wild predators, cats can be quite unpredictable. Many owners who are devoted to their cats complain that the cat often scratches them unexpectedly. One acquaintance had the cat declawed and found that the pet reverted to using its teeth on her!”

Can you believe it?!?! A woman had her cat declawed, and the cat bit her!

It’s not just that we know cats give off plenty of nonverbal warnings when they’re uncomfortable, or that declawing makes a cat much more likely to bite. Organizations like the Humane Society, SPCA, The Paw Project and others have been saying that for years.

It goes well beyond that — studies, including the most comprehensive study to date on the effects of declawing, have proven without a doubt that cats are much more likely to bite when they’re subjected to the cruel and painful declawing procedure. (See “Pain and adverse behavior in declawed cats,” a 2017 paper in the Journal of Feline Medicine and Surgery.)

That’s because declawing a cat not only inflicts a lifetime of physical pain and psychological trauma, it robs felines of their primary defense mechanism, making them feel much more vulnerable. Without claws with which to warn off unwanted handling, the poor declawed cats have only one defensive weapon available to them — their teeth.

An evolutionary psychologist should understand that, and should also understand that scratching is a natural and necessary behavior for cats. It’s not right or wrong, it’s cats being cats. Mutilating innocent animals to protect inanimate objects like furniture is objectively wrong and cruel. When you adopt a cat, scratching comes as part of the package along with all the positives like unconditional love, amusing antics and calming purring.

There are ways to dissuade and train your cats to mostly avoid scratching furniture, but no one should expect their cats will never put a claw on their couches. If you don’t want your furniture scratched, don’t get a cat. End of.

Does Your Cat Know Your Name? Study Says Maybe

If your cat doesn’t know your name, it’s nothing personal. You’re just a human, after all.

I’m pretty sure Buddy does not know my name, and why should he?

He doesn’t hear my name spoken often, and in his mind I’m probably “Big Dumb Benevolent Human And Butler,” or BDBHAB. That’s a mouthful, even in meow, thus the much easier-to-say “Big Buddy.”

But a new study from Japan claims cats “possibly” know the names of their humans.

First, the parameters of the study would have eliminated the Buddies from the start: the research team from Kyoto University enlisted only cats who lived with at least two other felines. This is because they also wanted to find out if cats knew the names of their furry roommates as well.

The 48 cats who participated in the study lived in regular homes or cat cafes. The team played a recording of their human calling the name of one of their buddies, while a monitor showed an image of a cat. Sometimes the names and the images matched, and sometimes they didn’t.

The cats took longer looks at the images when the feline image shown didn’t match the name they heard, which the researchers said was indicative of surprise.

Separately, 26 cats were run through a similar experiment. In that scenario, the researchers played an audio clip of the cat’s human’s name and showed an image of either the human caretaker, or a cat. Like they did with the first experiment, cats looked longer when the images didn’t match the names, expressing apparent puzzlement.

What's your name, dude? — “I’m a Buddy, you’re a Buddy. We’re all Buddies.”

In case you’re wondering, it does seem to matter if a cat grows up in a home rather than a cat cafe. When the name and face matched, researchers called that a “congruent condition.”

“Half of the trials were in a congruent condition where the name and face matched, and half were in an incongruent (mismatch) condition,” they wrote. “Results of Exp.1 showed that household cats paid attention to the monitor for longer in the incongruent condition, suggesting an expectancy violation effect; however, café cats did not.”

The reasons are fairly straightforward. In a home setting, cats almost always interact with their human family members, while felines in cafes interact with different employees on different shifts, and with customers, who might be regulars or strangers. Either way, the cats living in homes are much more likely to hear their own names and the names of their feline roommates.

“The latter probably have more opportunities to observe interactions between the owner and each of the other cohabitating cats, which might facilitate learning of the face–name relationship,” the team wrote.

The Kyoto team pointed out that many wild animals, particularly mammals and birds, make sounds that correspond to animals, objects or abstract ideas. Monkeys and birds, for example, use a range of different calls to communicate to each other when they’ve found food or spotted a predator heading their way.

The stakes are much lower in a home setting, but evolutionary traits can still serve cats and dogs well. One reason pets may be keen to recognize the names of their furry roommates, the research team speculated, is competition. After all, Socks would want to know if Oreo is getting more treats or head scritches.

Keeping Cats From Killing Local Wildlife May Be Easier Than We Think

Armed with real data, there’s a chance to stop horrific policies designed to kill millions of cats who are blamed for driving small wildlife species to extinction.

For the past two decades, a handful of birders and “conservationists” have claimed cats kill as many as 3.7 billion birds and 22.3 billion small animals every year in the US alone.

Their claims, repeatedly credulously in the press, have been catastrophic to cats: Hyperbolic headlines have labeled them “stone cold serial killers,” “God’s perfect little killing machines,” and posed questions like “Is your cat a mass murderer?” The headlines, often running in otherwise respectable publications, envision brutal “solutions,” like this one in Scientific American: “Cats Are Ruthless Killers. Should They Be Killed?”

Politicians, wildlife conservationists and birders read headlines like the examples above and come up with ruthless policies, like bounties offering $10 for cat scalps and $5 for kitten scalps, government employees stalking public parks with shotguns and literally gunning down strays, and an Australian program designed to kill millions of cats by air-dropping sausages laced with poison.

“They’ve got to taste good,” an Australian scientist who helped develop the sausage formula said. “They are the cat’s last meal.”

Now who’s the serial killer?

Sadly, few people have thought to question the studies that claim jaw-dropping numbers of birds and small mammals are slaughtered by cats every year.

How did the studies arrive at those numbers? Their formula hasn’t varied much from “study” to “study,” and more or less looks like this:

Assemble your data from old studies that have nothing to do with cats preying on wildlife, or hand out questionnaires to a handful of cat owners and ask them how many animals they think their free-roaming cats might kill.
Since you don’t know how many stray, feral and free-roaming cats exist in the US, invent an arbitrary number. Most of these “studies” put the number of cats anywhere between 25 and 125 million, but higher numbers are better because they make for more apocalyptic predictions and generate more credulous headlines.
Completely ignore the primary factors driving avian extinction in the world, which are human-caused: Habitat destruction, habitat defragmentation, wind turbines, pesticides, cars, high tension wires and windows, which are by far the biggest bird-killers.
Attribute all of the above to feral, stray and free-roaming cats.
Take your original “data” and, without making any adjustments for climate, regional variation, migration patterns, other predatory impacts — or anything else, really — simply extrapolate the total number of bird deaths by multiplying your small dataset by the total number of free-roaming cats in the US, which you invented back in Step 2.
Package the entire thing as a rigorous study by Serious Conservationists, write some apocalyptic press releases and hype up your claims in your abstracts, because you know the vast majority of web aggregators and overworked reporters will not have the time to take a deep dive into the text of your study.
Encourage activist groups and lawmakers to push for the mass culling of cats, based on your studies.

Please, don’t take my word for it. Read the text of any of the widely-cited studies that have been reported as gospel in the last 20 years. You’ll be astonished at what passes for rigorous scientific work, and how policies that determine the fates of millions of cats are largely shaped by these studies.

The D.C. Cat Count and the importance of a baseline

But there’s hope: A coalition of groups in Washington, D.C., spent more than three years methodically taking a “census” of that city’s cat population using a variety of methods.

They surveyed thousands of households within the city limits to find out how many cat owners allow their pets to roam free. They set up 1,530 trail cameras in wooded areas, ditches, alleys, alongside streams. The cameras are motion-activated and they produced more than five million images — including more than 1.2 million images of cats and more than four million images of local wildlife. The cameras captured photos of squirrels, coyotes, raccoons, possums, deer and even wild turkeys.

They assembled teams of dozens of volunteers to personally survey areas where cats are known to congregate. Then, when all the data was collected, they spent months sorting the results, carefully keeping tally, sorting duplicate sightings of individual cats and confirming data when necessary.

When all was said and done, after three years, $1.5 million and countless man-hours, the study determined there are some 200,000 cats living in Washington, D.C., and only about 3,000 of them are truly feral, meaning they’re not pets and not part of managed cat colonies.

The team — which brought together conservationists, bird lovers, cat lovers, shelter volunteers and others who would normally oppose each other on cat-related policies — also documented every step to provide a toolkit for other cities and local governments to conduct their own methodical head counts. They don’t have to reinvent the wheel to take D.C.’s admirable lead.

The leaders of the D.C. Cat Count went to all that trouble because they understood that without knowing exactly how many cats they’re dealing with, where they congregate and how they behave, any policies attempting to deal with their potential impact would be flawed and could end up doing more harm than good.

Making informed decisions about managing outdoor cats

Anyone who continues to cite the old, sloppy studies should be reminded, loudly and often, that they have led to years of failed policies, heartbreaking outcomes, enmity between cat lovers and birders, and widespread misunderstanding of how cats behave and the impact they have on wildlife.

Now the next phase begins: Dispensing with the hysteria and finding real, useful ways to minimize the predatory impact of cats on local wildlife populations.

One of the first follow-up studies to bear fruit comes, not coincidentally, from a research team in nearby Fairfax County, Virginia, and yields some surprising revelations about free-roaming cat behavior and impact.

The biggest takeaway: Because free-roaming cats almost always stick to small areas (spanning only 550 feet, or 170 meters), “cats were unlikely to prey on native wildlife, such as songbirds or small mammals, when they were farther than roughly 1,500 feet (500 meters) from a forested area, such as a park or wooded backyard. We also found that when cats were approximately 800 feet (250 meters) or farther from forest edges, they were more likely to prey on rats than on native wildlife.”

That’s it. In other words, small buffer zones are “the difference between a diet that consists exclusively of native species and one without any native prey,” the study’s authors wrote.

“Our findings suggest that focusing efforts on managing cat populations near forested areas may be a more effective conservation strategy than attempting to manage an entire city’s outdoor cat population,” wrote Daniel Herrera and Travis Gallo of George Mason University.

In other words, minimizing the predatory impact of cats is likely a hyper-local affair, and not something that can be effectively managed on a one-size-fits-all city-wide or county-wide basis.

This is just a first step in the right direction, and follow-up studies will yield further insights that will hopefully lead to fine-tuning strategies in managing free-roaming cats.

We still feel keeping cats indoors — for their own safety, as well as the safety of other animals — is the right thing to do, and all the evidence supports that view.

But what these efforts have shown us is that there is a way forward, and it’s not the contentious, divisive and irresponsible work that has guided cat management policy for two decades. It’s not just possible, but necessary, for all sides to work together to find solutions.

Let’s hope more people realize that, and the old “studies” are relegated to the dustbin where they belong.
