Why the TSA Prefers Dogs With Floppy Ears Rather Than Pointy Ones

When the Transportation Security Administration “hires” dogs to work at passenger screening zones in airports, its employees will be checking for one specific physical trait. Do the dog's ears hang low? Do they wobble to and fro? If so, they just might be the right dog for the job.

According to ABC News, the TSA will now give priority to floppy-eared dogs over pointy-eared ones, but only in sections of the airport where passengers and bags are screened. That’s because the new policy has nothing to do with differences in how the breeds perform (there are none) and everything to do with how comfortable passengers feel around the dogs.

David Pekoske, head of the TSA, says floppy-eared dogs like Labrador and golden retrievers tend to be perceived as friendlier and less threatening than pointy-eared dogs like German shepherds, even if this isn't rooted in reality. The TSA noticed that Labs have a calming effect on travelers—especially children—while German shepherds often do the opposite.

“You'll see parents kind of pull their kids away from a dog with pointy ears because, I think, we as a culture recognize that as a tactical dog or a police dog," TSA assistant administrator Michael Bilello tells ABC News.

However, that doesn’t mean the pointy-eared pooches will be out of a job soon. Bilello says the “health and operational capabilities” of a dog are still more important than the shape of her ears, and no dog will be removed from its current post due to the new policy. The only change is that floppy-eared dogs, if available, will be given preference for openings in passenger screening areas. Roughly four in five recent canine recruits have ears that fall flat, and this is a ratio the TSA hopes to stick with.

According to The Washington Post, the TSA uses about 1200 dogs of seven different breeds for passenger screening purposes. Only two of those breeds—German shepherds and Belgian Malinoises—have pointy ears.

13 Fascinating Facts About Pallas’s Cats

Far across the world, an elusive—and adorable—wildcat called the Pallas’s cat (also known as the manul) roams the grasslands and steppes of Central Asia and Eurasia. Get to know the flat-faced, furry kitty, which has been featured in memes and viral videos and recently received its own wildlife preserve in Asia’s Altai Mountains.

1. It's named after naturalist Peter Pallas.

German naturalist Peter Pallas first described the furry wildcat in 1776. He named the kitty Felis manul, and theorized that it was an ancestor of the Persian cat, due to its round face, luxurious coat, and stocky body. (He was wrong.)

2. Its scientific name means "ugly-eared."

Later on, the cat's scientific name was changed from Felis manul to Otocolobus manul—not exactly the most flattering moniker, since Otocolobus is Greek for “ugly-eared.”

3. Its unusual ears come in handy.

Some may consider the Pallas’s cat’s ears to be ugly, while others might think they’re adorable. Arguments aside, the cat’s round ears—which sit flat on the sides of its head—are one of the feline's most distinguishing features. As Crystal DiMiceli, a former wild animal keeper at Brooklyn's Prospect Park Zoo, explains in the above video, having low-positioned ears helps the cat conceal itself—they don’t poke up to reveal the animal's position while it's hiding or hunting.

4. It has a dense, plush coat.

The coat of the Pallas's cat is its true crowning glory. It’s longer and denser than any other coat belonging to a member of the Felid species (growing in even heavier in the winter), and the undercoat on its belly is twice as long as the fur covering the rest of its body. The shade ranges from silvery grey during the winter to a darker, red-toned hue during warmer months. (Some cats are also red, particularly in Central Asia.) Its broad head is streaked and speckled with dark markings, and its bushy tail is banded with stripes and a dark tip. These markings tend to appear darker during the summer.

5. Its fur blends with its habitat, which conceals it from predators.

Pallas's cats live in areas ranging from Pakistan and northern India to central China, Mongolia, and southern Russia. According to Wild Cats of the World, by Luke Hunter, its body isn’t adapted for snow, so it sticks to cold, arid habitats—particularly grassy or rocky areas, which help conceal it from predators—at elevations of around 1500 to nearly 17,000 feet. The stocky cat isn’t a fast runner, so when it senses danger, it freezes and crouches flat and motionless on the ground, and its fur helps it blend in with its surroundings.

6. Pallas's cats aren't fat—they're just furry.

Pallas's cats typically weigh less than 12 pounds, and they’re usually only 2 feet or less in body length—meaning they’re not that much larger than an ordinary house cat. Yet their dense coat of fur makes them appear much larger.

7. Their pupils are round instead of vertical.

Pallas's cats do share one feature in common with larger wildcats, like lions and tigers: their eyes. Their pupils are round, whereas a house cat's pupils are vertical and slit-shaped. Wondering why some cats have round pupils while others have vertical ones? A 2015 study conducted by researchers at the University of California, Berkeley found that animals’ pupil shapes might indicate their role in the predator/prey food chain. They analyzed 214 species of land animals (including cats), and noted that species with vertical pupils tended to be ambush predators that were active during both day and night. In contrast, species with vertical pupils were often “active foragers,” meaning they chase their prey. Also, predators that are closer to the ground, like house cats, were prone to vertical pupils, whereas larger wildcats had round ones. Pallas’s cats are small, and they are primarily ambush hunters, so the jury’s still out on whether the study's findings hold true for all creatures.

8. They subsist mostly on pika.

Pallas's cats are ambush hunters and spend much of their time hunting pika, a small mammal, and other critters like gerbils, voles, hares, ground squirrels, birds, and young marmots. Pika typically make up more than 50 percent of the cat's diet. 

9. They may be distantly related to the leopard cat.

Peter Pallas thought the animal was related to the Persian cat. (We think it looks like a Maine Coon and a Scottish Fold had a baby and weaned it on steroid milk.) However, experts have uncovered evidence that the wildcat’s nearest—yet still pretty distant—relative might be the leopard cat.

10. They's not social animals.

The Pallas's cat is notoriously elusive and spends much of its time hiding in caves, crevices, or abandoned burrows.

11. They don't seem to like each other much.

Pallas's cats may be adorably fluffy, but they aren’t the world’s sweetest, most cuddly creatures. In fact, they’re very aggressive. Case in point: In The Wild Cat Book, authors Fiona and Mel Sunquist recount an anecdote provided by Bill Swanson, the Cincinnati Zoo’s director of animal research. Zookeepers thought that a litter of newborn Pallas's cats were having difficulty breathing, but “when they listened closely, they realized that the noise they were hearing was the kittens growling and hissing at each other—before they had even opened their eyes!"

12. Their mating period is brief.

Pallas’s cats mate between December and March; the females typically give birth between the end of March and May, after a gestation period of 66 to 75 days. Pallas’s cats usually give birth to three or four kittens, but litters can sometimes have as many as eight kittens. Kittens become independent by four to five months, and when they reach nine to 10 months, they’re mature enough to reproduce. 

13. They're classified as "near-threatened."

It's estimated that Pallas's cats can live up to six years in the wild, but because of predators and other dangers, their lifespan is likely to be half this length. In captivity, they’ve been known to survive for nearly 12 years.

In 2002, the International Union for Conservation of Nature classified the Pallas’s cat as “near-threatened,” and that status remains today. Many factors contribute to their low numbers, including farming, agricultural activities, mining, and poisoning campaigns aimed at reducing pika and marmot populations. They're also often killed in traps meant for wolves and foxes, or by domestic dogs. And despite international trading bans and legal protections in some countries, they're often hunted for their fur. (The cat's fat and organs are also used to make traditional medicines.) 

Scientists don't have enough data to estimate the Pallas’s cat's population size, but due to their scarcity and the many threats they face, experts believe that their numbers have dropped by 10 to 15 percent over the past decade or so. To better understand—and protect—the animal, an international team of conservationists recently secured a 12-mile swath of land in Sailyugemsky Nature Park, which lies in the Altai Mountains between Kazakhstan and Mongolia, as a sanctuary for the rare cat. There, they hope to monitor its population, study its habitat, and build a database of information detailing encounters with it.

Australian Island Wants Visitors to Stop Taking Wombat Selfies

Spending a day observing Australian wildlife from afar isn't enough for some tourists. On Maria Island, just off the east coast of Tasmania, many visitors can't resist snapping pictures with the local wombats—and the problem has gotten so out of hand that island officials are asking people to pledge to leave the cute marsupials out of their selfies.

As CNN Travel reports, the Maria Island Pledge has been posted on signs welcoming visitors to the national park. It implores them to vow to the island to "respect and protect the furred and feathered residents." It even makes specific mention of the wombat selfie trend, with one passage reading:

"Wombats, when you trundle past me I pledge I will not chase you with my selfie stick, or get too close to your babies. I will not surround you, or try and pick you up. I will make sure I don’t leave rubbish or food from my morning tea. I pledge to let you stay wild."

The pledge isn't a binding contract guests have to sign. Rather, park officials hope that seeing these signs when they arrive will be enough to remind visitors that their presence has an impact on the resident wildlife and to be respectful of their surroundings.

The adorable, cube-pooping wombats at Maria Island are wild animals that aren't accustomed to posing for pictures, and should therefore be left alone—though in other parts of Australia, conservationists encourage tourists to take wildlife selfies. Rottnest Island off the country's west coast is home to 10,000 quokkas (another photogenic marsupial), and the quokka selfies taken there help raise awareness of their vulnerable status.
