Why Are Cats Afraid of Cucumbers?

Thanks to the internet, felines around the globe seem to have found a new—and unlikely—foe: the seemingly harmless garden cucumber. You’ve likely seen viral video compilations of pet owners surprising their cats with the fruit (yes, a cucumber is technically a fruit), which include footage of frightened kitties jumping, running, or clawing at the mysterious green objects before them.

Are cats and cucumbers really mortal enemies? Did an early feline ancestor eat a bad salad, or find that cucumbers made terrible scratching posts? “No, I don’t think that cats are inherently afraid of cucumbers,” Mikel Delgado, a certified cat behavior consultant who studied animal behavior and human-pet relationships as a PhD student at the University of California, Berkeley, tells Mental Floss.

Cats are creatures of habit, and Delgado thinks the cats in those videos—who were often ambushed from behind while bent forward eating—were simply caught off-guard while engaging in a familiar activity.

“Their eyes face forward, much like ours do,” Delgado explains. “That’s a very common structure for a face in a predator—you’re looking forward, and you’re not as worried about seeing behind you. Personally, I think that a lot of people were inadvertently startling their cats when they were already distracted. They were putting a strange object behind the cat while it was eating, the cat can’t see the object, they’re focused [on their food], and then they turn around” and see a cucumber.

The cats’ fright could be likened to how we sometimes jump or scream after we turn around and see someone standing behind us. But even though we typically laugh these moments off once the adrenaline dies down, it’s not cool to subject your cat to the same unsettling experience—especially when it’s eating.

“You want cats to feel safe when they eat,” Delgado says. “If cats don’t eat, they can become sick quite fast, and develop what’s called fatty liver disease.”

Plus, “stress can have really serious health effects on cats,” Delgado adds. “There’s been research showing that something as trivial as changing their routine can cause cats to exhibit what we call sickness behaviors: vomiting, not using their litter box, diarrhea, changes in appetite. Cats are sensitive.”

This doesn’t mean that you can’t introduce new items (say, a couch in the spot where your cat typically likes to sleep) to your household. But when you do, let Fluffy check out these unfamiliar objects on his or her own terms.

“A lot of the time people try to show a cat that something they’re afraid of isn’t scary,” Delgado says. “They’re going to inadvertently make the cat more afraid, because they’re forcing it to interact with something they’re fearful of.”

As time passes, the object will start smelling familiar, and your favorite feline will gradually relax. In the meantime, though, save the cucumbers for your salad, and keep them far away from your kitty’s food dish.

Why is Friday the 13th Considered Unlucky?

Today, people around the globe will feel uneasy about getting out of bed, leaving their homes, or going about their normal daily routines, all because of a superstition. These unfortunate folks suffer from paraskavedekatriaphobia, a common neurosis familiar to us all: the fear of Friday the 13th. But just where did this superstitious association come from, and how did it catch on?

The truth is that no one is absolutely sure where the idea that Friday the 13th is unlucky originated. Donald Dossey, the founder of the Stress Management Center and Phobia Institute in Asheville, North Carolina, suspects the fear can be traced back to a Norse myth about 12 gods who had a dinner at Valhalla—the fabled hall where legendary Norse heroes feasted for eternity after they died—that was interrupted by a 13th guest, the evil and mischievous god Loki.

According to legend, Loki tricked Höðr (the blind god of winter and son of Odin, the supreme god in Norse mythology) into shooting his brother Baldr (the benevolent god of summer who was also a son of Odin) with a magical spear tipped with mistletoe—the only substance that could defeat him. Thus the number 13 was branded as unlucky because of the ominous period of mourning following the loss of such powerful gods by this unwanted 13th guest.

For whatever reason, among many cultures, the number 12 emerged throughout history as a "complete" number: There are 12 months in a year, 12 signs of the zodiac, 12 Gods of Olympus, 12 sons of Odin, 12 labors of Hercules, 12 Jyotirlingas or Hindu shrines where Shiva is worshipped, 12 successors of Muhammad in Shia Islam, and 12 tribes of Israel. In Christianity, Jesus was betrayed by one of his 12 Apostles—Judas—who was the 13th guest to arrive for the Last Supper. Surpassing the number 12 ostensibly unbalances the ideal nature of things; because it is seen as irregular and disrespectful of a sense of perfection, the number 13 bears the stigma of misfortune and bad luck we know today.

WHY FRIDAY?

Friday joins in the mix mostly because all of the early accounts of Jesus’s crucifixion agree that it took place on Friday—the standard day for crucifixions in Rome. As Chaucer noted in The Canterbury Tales, "And on a Friday fell all this mischance." Yet perpetuating Friday as an unlucky day in America came from the late 19th-century American tradition of holding all executions on Fridays; Friday the 13th became the unluckiest of days simply because it combined two distinct superstitions into one. According to the Oxford University Press Dictionary of Superstitions, the first reference to Friday the 13th itself wasn’t until 1913. (So despite actually occurring on Friday, October 13, 1307, the popular notion that the Friday the 13th stigma comes from the date on which the famed order of the Knights Templar were wiped out by King Philip of France is just a coincidence.)

The repercussions of these phobias reverberated through American culture, particularly in the 20th century. Most skyscrapers and hotels lack a 13th floor, which specifically comes from the tendency in the early 1900s for buildings in New York City to omit the unlucky number (though the Empire State Building has a 13th floor). Some street addresses also skip from 12 to 14, while airports may skip the 13th gate. Allegedly, the popular Friday the 13th films were so-named just to cash in on this menacing date recognition, not because the filmmakers actually believed the date to be unlucky.

So, is Friday the 13th actually unlucky? Despite centuries of superstitious behavior, it largely seems like psychological mumbo jumbo. One 1993 study seemed to reveal that, statistically speaking, Friday the 13th is unlucky, but the study's authors told LiveScience that though the data was accurate, "the paper was just a bit of fun and not to be taken seriously." Other studies have shown no correlation between things like increased accidents or injuries and Friday the 13th.

And Friday the 13th isn't a big deal in other cultures, which have their own unlucky days: Greeks and Spanish-speaking countries consider Tuesday the 13th to be the unluckiest day, while Italians steer clear of Friday the 17th. So today, try to rest a little easy—Friday the 13th may not be so unlucky after all.

Does the Full Moon Really Make People Act Crazy?

Along with Mercury in retrograde, the full moon is a pretty popular scapegoat for bad luck and bizarre behavior. Encounter someone acting strangely? Blame it on the lunar phases! It's said that crime rates increase and emergency rooms are much busier during the full moon (though a 2004 study debunked this claim). Plus, there's that whole werewolf thing. Why would this be? The reasoning is that the moon, which affects the ocean's tides, probably exerts a similar effect on us, because the human body is made mostly of water.

This belief that the moon influences behavior is so widely held—reportedly, even 80 percent of nurses and 64 percent of doctors think it's true, according to a 1987 paper published in the Journal of Emergency Medicine [PDF]—that in 2012 a team of researchers at Université Laval's School of Psychology in Canada decided to find out if mental illness and the phases of the moon are linked [PDF].

To test the theory, the researchers evaluated 771 patients who visited emergency rooms at two hospitals in Montreal between March 2005 and April 2008. The patients chosen complained of chest pains, which doctors could not determine a medical cause for the pains. Many of the patients suffered from panic attacks, anxiety and mood disorders, or suicidal thoughts.

When the researchers compared the time of the visits to the phases of the moon, they found that there was no link between the incidence of psychological problems and the four lunar phases, with one exception: in the last lunar quarter, anxiety disorders were 32 percent less frequent. "This may be coincidental or due to factors we did not take into account," Dr. Geneviève Belleville, who directed the team of researchers, said. "But one thing is certain: we observed no full-moon or new-moon effect on psychological problems."

So rest easy (or maybe not): If people seem to act crazy during the full moon, their behavior is likely pretty similar during the rest of the lunar cycle as well.
