12 Furry Facts About Red Pandas

Red pandas have always lived in the shadow of the other, more famous panda. But now it's time to give the little guy its due.

1. THEY HAVE TWO EXTINCT RELATIVES.

Currently, red pandas live in the Eastern Himalayas. But the first red panda fossil was found a little bit further afield than that—in the United Kingdom. In 1888, a fossil molar and lower jaw of a cougar-sized animal called the Giant Panda (unrelated to the modern giant panda) were discovered. More fossils have been found in Spain, Eastern Europe, and even the United States. Around 5 million years ago, Tennessee was home to a giant red panda that probably went extinct with the arrival of raccoons.

2. THEY'RE VEGETARIAN CARNIVORES.

It might seem like an oxymoron, but carnivore in this case doesn't mean meat eater. Carnivore is a biological order that includes groups like bears, dogs, and cats, and while these animals are generally carnivores, some are omnivores, and some are vegetarians. Red pandas are classified as carnivores because they're descended from the same ancestors as the other carnivores, but they rarely eat anything other than bamboo and a few insects. And while giant pandas eat all of a bamboo plant, red pandas eat only the young leaves. Because this is such a nutritionally poor food source, they need to spend 13 hours a day eating and looking for food and can lose upwards of 15 percent of their body weight in winter.

3. THEY'RE SLIGHTLY BIGGER THAN A DOMESTIC CAT.

But their tails add as much as 18 inches to their length. Red pandas live solitary lives in trees, high up in the mountains, so they wrap those big, bushy tails around themselves to keep warm. (They also use them for balance.)

4. THEY HAVE A FALSE THUMB.

This is another feature (along with diet) that red pandas and giant pandas share. Because both pandas have false thumbs—which is actually an extended wrist bone—it was thought that it must be an adaption to eating bamboo. But the red panda's more carnivorous ancestors had this feature as well. According to a 2006 study, what happened was "one of the most dramatic cases of convergence among vertebrates." Convergent evolution is when two unrelated animals faced with similar circumstances evolve to look similar. In this case, the red panda's false thumb evolved to help it climb trees, and only later became adapted for the bamboo diet, while giant pandas evolved this virtually identical feature because of their bamboo diet.

5. THEY'RE ESCAPE ARTISTS.

Rusty the red panda had been at the Smithsonian National Zoo for just three weeks when he made a break for it in June 2013. His method of escape? A tree branch that was pushed down over his enclosure's electric fence by heavy rains. The ensuing panda hunt (and endless bad jokes about panda-monium) captivated Twitter (tweeters used the hashtag #findrusty) until he was found in a nearby neighborhood. Soon after his daring escape, Rusty became a father, forcing him to put his wild youth behind him and settle down. But it could have been worse. After a similar escape in Dresden, Germany, the authorities got another red panda down from a tree by using a fire hose to spray it with water. The panda fell 30 feet to the ground, giving it a concussion. (Ultimately, the animal was OK.)

Red pandas have also escaped from zoos in London, Birmingham, and Rotterdam. The Association of Zoos and Aquariums even warn in their official care manual "beware: red pandas are escape artists" [PDF].

6. ONE ESCAPE LED TO SOMETHING CALLED THE RED PANDA EFFECT.

Sadly, the red panda involved in the 1978 Rotterdam escape was found dead not long after the search for it began. But the event led to a very peculiar psychological observation. Even after the body of the panda was found, more than 100 people reported seeing it, very much alive. These sightings were clearly mistaken; there's no reason to think that multiple red pandas were loose in Rotterdam, and red pandas are distinctive enough that mistaking them for a dog or cat was unlikely. It's believed that people expected to see a red panda, so they saw one, even though there wasn't one there; researchers called it the Red Panda Effect.

7. THERE'S AN INTERNET BROWSER NAMED AFTER THEM.

Mozilla's flagship browser, Firefox, means red panda. Originally, Mozilla wanted to name the browser Firebird, but found that another open source project was using that name. Not wanting to upset anyone, they decided to go with Firefox, another name for the red panda. And in a true example of adorableness, in 2010 Mozilla adopted two baby red pandas that had been born at Tennessee's Knoxville Zoo.

8. THERE IS ONLY ONE TRUE PANDA—AND YOU CAN PROBABLY GUESS WHICH ONE IT IS.

After the red panda was discovered in the 1820s, it was just called the panda (the origin of the name is controversial, but it probably comes from the Nepali word ponya, meaning "bamboo or plant eating animal"). Forty years later, Europeans found a new animal in China and called it the Parti-Colored bear—because unlike polar bears, black bears, or brown bears it was multi-colored.

9. THERE HAS BEEN A 140-YEAR TAXONOMIC MIX-UP.

Prepare to be confused: In the late 19th century, scientists noticed that the parti-colored bear and the (red) panda were very similar. Their jaws were more like each other than they were like any other animal, they lived near each other, they both had false thumbs, and their diets were similar. The decision was made to officially consider the (red) panda as a type of bear.

By the early 20th century, that decision was reversed: Parti-colored bears were declared bears, and (red) pandas were classified as cousins of the raccoon.

Then, in the 1910s, it was decided that parti-colored bears weren't actually bears at all, but were actually large pandas, and also distant relatives of the raccoon. But because parti-colored bears weren't classed as bears anymore, they had to have a name change. They became giant pandas, while the one true panda was renamed the red or lesser panda (to quote a 1920 issue of Popular Science: "Zoologists reverently refer to this rare beast as the "giant panda." Its more popular cognomen is the 'bear-raccoon'").

10. BUT RED PANDAS ARE THEIR OWN THING.

By the 1980s, genetic evidence indicated that giant pandas actually were a type of bear, and red pandas belonged in their own family, the Ailuridae. They might seem similar, but they're not related.

All of this means that if you're the type of person who rolls their eyes when someone calls a bison a buffalo, or a koala a bear, you need to stop calling the bear a panda and instead refer to it as a "parti-colored bear," the original English name (but if you wanted to call it the bear-raccoon, no one would stop you). Giant pandas are not pandas. There is only one true panda.

11. BUT THIS DOESN'T AFFECT KUNG FU PANDA 3.

There's still a kung fu panda in the series: Shifu, a red panda.

12. THEY'RE ENDANGERED.

According to the World Wildlife Fund, there are fewer than 10,000 red pandas left in the wild. Habitat destruction increases the species' chances of extinction.

Potato-Based Pet Food Could Be Linked to Heart Disease in Dogs

If you have a pup at home, you may want to check the ingredients listed on that bag of dog food in your cupboard. The U.S. Food & Drug Administration has warned that potato-based pet foods might be linked to heart disease in dogs, Time reports.

Foods containing lentils, peas, and other legume seeds are also a potential risk, the agency’s Center for Veterinary Medicine announced.

“We are concerned about reports of canine heart disease, known as dilated cardiomyopathy (DCM), in dogs that ate certain pet foods containing peas, lentils, other legumes or potatoes as their main ingredients,” Martine Hartogensis of the veterinary center said in a statement. “These reports are highly unusual as they are occurring in breeds not typically genetically prone to the disease.”

Recent cases of heart disease have been reported in various breeds—including golden and Labrador retrievers, miniature schnauzers, a whippet, a shih tzu, and a bulldog—and it was determined that all of the dogs had eaten food containing potatoes, peas, or lentils.

While heart disease is common in large dogs like Great Danes and Saint Bernards, it’s less common in small and medium-sized breeds (with the exception of cocker spaniels). If caught early enough, a dog’s heart function may improve with veterinary treatment and dietary changes, the FDA notes. While the department is still investigating the potential link, it’s best to err on the side of caution and avoid foods containing these ingredients until further notice.

As shown by the recent romaine lettuce scare linked to E. coli, the FDA is unable to request a food recall unless a specific manufacturer or supplier can be identified as the source of contamination. Instead, public notices are generally issued to warn consumers about a certain food while the agency continues its probe.

10 Science-Backed Tips for Getting a Cat to Like You

Like so many other humans, you might find cats to be mysterious creatures. But believe it or not, it’s not that hard to make friends with a feline, if you know what to do. Here are some tips on how to effectively buddy up with a kitty, drawn from scientific studies and my own experience as a researcher and cat behavioral consultant.

1. LET THE CAT CALL THE SHOTS.

When we see cats, we really want to pet them—but according to two Swiss studies, the best approach is to let kitty make the first move.

Research done in 51 Swiss homes with cats has shown that when humans sit back and wait—and focus on something else, like a good book—a cat is more likely to approach, and less likely to withdraw when people respond. (This preference explains why so many kitties are attracted to people with allergies—because allergic people are usually trying to not pet them.) Another study found that interactions last longer and are more positive when the kitty both initiates the activity and decides when it ends. Play a little hard to get, and you might find that they can’t get enough of you.

2. APPROACH A CAT THE WAY THEY GREET EACH OTHER (SORT OF).

Felines who are friendly with each other greet each other nose to nose. You can mimic that behavior by offering a non-threatening finger tip at their nose level, a few inches away. Don’t hover, just bend down and gently extend your hand. Many cats will walk up and sniff your finger, and may even rub into it. Now that's a successful greeting.

3. PET CATS WHERE THEY LIKE IT MOST …

They're very sensitive to touch, and generally, they tend to like being petted in some places more than others. A small 2002 study demonstrated that cats showed more positive responses—like purring, blinking, and kneading their paws—to petting on the forehead area and the cheeks. They were more likely to react negatively—by hissing, swatting, or swishing their tails—when petted in the tail area. A more recent study validated these findings with a larger sample size—and many owners can testify to these preferences.

Of course, every animal is an individual, but these studies give us a good starting point, especially if you're meeting a cat for the first time.

4. … AND IF YOU GET NEGATIVE FEEDBACK, GIVE THE CAT SOME SPACE.

There are plenty of signs that a cat doesn't like your actions. These can range from the overt—such as hissing and biting—to the more subtle: flattening their ears, looking at your hand, or twitching their tails. When you get one of those signals, it’s time to back off.

Many of the owners I work with to correct behavioral issues don't retreat when they should, partially because they enjoy the experience of petting their cat so much that they fail to recognize that kitty isn’t enjoying it too. You can’t force a feline to like being handled (this is especially true of feral cats), but when they learn that you’ll respect their terms, the more likely they will be to trust you—and come back for more attention when they're ready.

5. DON’T OVERFEED YOUR CAT.

Many think that food equals love, and that withholding food might make your kitty hate you, but a recent study of obese felines from Cornell University showed the opposite is true—at least for a period of time. About a month after 58 overweight kitties were placed on a diet, three-quarters of their owners reported that their dieting felines were more affectionate, purred more often, and were more likely to sit in their owner's lap. This adorable behavior came with some not-so-cute side effects—the cats also begged and meowed more—but by week eight, both the good and bad behavior had abated for about half the animals.

Regardless of whether a diet makes your pet cuddlier, keeping your pet on the slender side is a great way to help them stay healthy and ward off problems like diabetes, joint pain, and uncleanliness. (Overweight animals have difficulty grooming themselves—and do you really want them sitting on your lap if they can’t keep their butt clean?)

6. PLAY WITH THEM—A LOT.

Most of the behavior problems that I've witnessed stem from boredom and a lack of routine playtime. No one thinks twice about walking their dog every day, but many people fail to recognize that felines are stealth predators who need a regular outlet for that energy. A recent study suggested that cats prefer human interaction over food, but a closer look at the data demonstrated that what really attracted them to humans was the presence of an interactive toy. One of their top choices is a wand-style toy with feathers, strings, or other prey-like attachments that evoke predatory behavior. Daily interactive play is a great way to bond with them when they’re not in the mood to cuddle—and to keep them fit. Try the Go-Cat Da Bird or any of Neko Flies interchangeable cat toys.  

7. KEEP YOUR CAT INDOORS.

A study conducted in Italy showed that felines who stayed mostly indoors (they had one hour of supervised access to a small garden each day) were more “in sync” with their owners than felines who were allowed free access to the outdoors. The indoor kitties were more active during the day, when their owners were likely to be active, and less active at night, when humans like to sleep. (Many people believe cats are nocturnal, but they are naturally crepuscular—active at dawn and dusk.)

8. SOCIALIZE CATS WHEN THEY'RE YOUNG.

Multiple studies have shown that just a few minutes a day of positive handling by humans helps kittens grow up to be friendlier and more trusting of humans. The ideal age to socialize kittens is when they're between 2 and 9 weeks old. One 2008 study found that shelter kittens that had been given a lot of "enhanced socialization"—additional attention, affection, and play—were, a year later, more affectionate with their owners and less fearful than other kittens adopted from the same shelters.

You can help socialize kittens by volunteering as a foster caretaker. Fostering ensures they get plenty of interaction with people, which will help them will be comfortable around potential adopters. You'll also be doing your local shelter a huge favor by alleviating overcrowding.

9. TAKE THE CAT'S PERSONALITY—AND YOUR OWN—INTO CONSIDERATION WHEN ADOPTING.

If you want to adopt an older animal, take some time at the shelter to get to know them first, since adopters of adult cats report that personality played a big role in their decision to take an animal home permanently and had an impact on their satisfaction with their new companion. Better yet, foster one first. Shelters can be stressful, so you'll get a better sense of what an animal is really like when they're in your home. Not all cats are socialized well when they're young, so a cat may have their own unique rules about what kinds of interactions they're okay with.

It's also key to remember that a cat's appearance isn't indicative of their personality—and it's not just black cats who get a bad rap. In 2012, I published a study with 189 participants that showed that people were likely to assign personality traits to felines based solely on their fur color. Among other things, they tended to think orange cats would be the nicest and white cats the most aloof. (Needless to say, these are inaccurate assumptions.) And it's not just the kitty's personality that matters—yours is important too. Another study I conducted in 2014 of nearly 1100 pet owners suggested that self-identified “cat people” tend to be more introverted and anxious when compared to dog people. (We’re also more prone to being open-minded and creative, so it’s not all bad.) If you’re outgoing and active, a more playful feline could be for you. If you prefer nights spent snuggling on the couch, a mellow, shy-but-sweet lovebug could be your perfect pet.

10. BE A KEEN OBSERVER OF THEIR BEHAVIOR.

Overall, use your common sense. Be a diligent and objective observer of how they respond to your actions. Feline body language can be subtle—something as small as an eye-blink can indicate contentment, while ear twitches might signal irritation—but as you learn their cues, you'll find yourself much more in tune with how they're feeling. And if you adjust your behaviors accordingly, you'll find soon enough that you've earned a cat's trust.
