10 Scientific Benefits of Being a Cat Owner

Studies have shown that just watching cat videos on the internet can boost a person's energy and create positive emotions—so it's no surprise that actual cat ownership has a number of benefits. Here are a few.


If you're worried about your carbon footprint, it’s better to own a cat than a dog. A 2009 study found that the resources needed to feed a dog over the course of its life create the same eco-footprint as that of a Land Cruiser. Meanwhile, cats—which eat less in general and are more likely to eat fish than corn- or beef-flavored products—only have the approximate carbon footprint of a small hatchback.


Losing a loved one is incredibly painful, but one of the best ways of coping is to own a pet. Cats have been shown to help people get over their loss more quickly, and show less physical symptoms of pain, like crying. Despite the fact that they are only animals, cats serve as a social support during difficult times. People in mourning report talking to their pet to work out their feelings, since it is often easier to talk to something that won’t respond and can’t judge than to another human being.


If you’re a single guy and you can’t seem to get a date, get a cat! A British poll found that 82 percent of women agreed they are more attracted to men who like animals. And while having a dog will do wonders for your dating life, a whopping 90 percent of single women said that men who own a cat are “nicer” than other guys. Listing that you own a cat on your dating profile could do wonders for the number of responses you get—but remember, a cat is for life, not just until you find a partner.


A 2010 survey of British pet owners by the University of Bristol found that people who owned cats were more likely to have college degrees than their dog loving counterparts. In 2014, a researcher in Wisconsin surveyed 600 college students and found that cat owners were actually more intelligent as well. (But it's probably not the cat itself making the owner smarter: The researchers conducting the Bristol survey said that smarter people tend to work longer hours, and since cats require less attention than dogs, they are a better choice for the busy intellectual.)


Owning any pet is good for your heart. Cats in particular lower your stress level—possibly since they don’t require as much effort as dogs—and lower the amount of anxiety in your life. Petting a cat has a positive calming effect. One study found that over a 10-year period cat owners were 30 percent less likely to die of a heart attack or stroke than non-cat owners (although this might just be because cat owners are more relaxed and have lower stress in general).


The stereotype that dogs are more affectionate than cats is just that: a stereotype. In fact, it turns out that cats can be just as good of companions as dogs, especially for women. An Austrian study conducted in 2003 found that having a cat in the house is the emotional equivalent of having a romantic partner. As well as initiating contact much of the time, studies have shown cats will remember kindness shown to them and return the favor later.

But cats really do have the upper hand in these relationships. After thousands of years of domestication, cats have learned how to make a half purr/half howl noise that sounds remarkably like a human baby’s cry. And since our brains are programmed to respond to our children’s distress, it is almost impossible to ignore what a cat wants when it demands it like that.


Your choice of pet reveals something about your personality. While dog lovers tend to be the life of the party, cat owners are quieter and more introverted. However, they score very highly when it comes to how trustworthy they are and how much they trust other people. Cat owners are also less manipulative and more modest.


Several studies and polls in the UK have found that people (especially women) prefer to sleep with their cats than with their partners, and they even report sleeping better with a cat than with a human. A recent study from the Mayo Clinic Center for Sleep Medicine indicates that they might be on to something: 41 percent of the people in that study indicated that they slept better because of their pet, while only 20 percent said that it led to disturbances.


Sadly, it’s too late for you, but if you have a child on the way, it might be time to get a cat. In 2002, the National Institutes of Health released a study that found children under a year old who were exposed to a cat were less likely to develop allergies—and not just pet allergies. According to Marshall Plaut, M.D., chief of the allergic mechanisms section at the National Institute of Allergy and Infectious Diseases, "high pet exposure early in life appears to protect against not only pet allergy but also other types of common allergies, such as allergy to dust mites, ragweed, and grass." And while the cat parasite Toxoplasma gondii is a threat to young children, experts say that by changing your cat’s litter box every day and keeping the animal indoors, you should be safe and allergy free!


Cats have a reputation of being aloof and not caring about their humans, but they have saved countless lives over the years. One cat in the United Kingdom warns her human when he’s about to have an epileptic seizure, while a cat in Montana woke up its two humans when a gas pipe started leaking. Firefighters told the couple that the house could easily have exploded if not for cat’s intervention.

One cat has even received the highest medal available to military animals. Simon the cat was onboard the HMS Amethyst, which was sailing up the Yangtze in 1949 when a shell hit the ship, killing several marines and severely injuring Simon. (The event marked the beginning of the 101-day siege of the ship, which would become known as the Yangtze Incident.) Simon was fixed up, and despite being injured, performed his ship duty and started catching the rats that were threatening the ship’s food supply, as well as providing moral support for the surviving sailors. Simon died not long after the ship returned to the UK, but he was posthumously awarded the UK’s Dickin Medal, recognized as the animal Victoria Cross, for "behaviour [of] the highest order, although the blast was capable of making a hole over a foot in diameter in a steel plate."

The World's Last Male Northern White Rhino Has Died, But Could He Still Help Save the Species?

Following age-related complications, Sudan the northern white rhinoceros was euthanized by a team of vets in Kenya at 45 years old, CNN reports. He was one of only three northern white rhinos left on Earth and the last male of his subspecies. For years, Sudan had represented the final hope for the survival of his kind, but now scientists have a back-up plan: Using Sudan's sperm, they may be able to continue his genetic line even after his death.

Northern white rhino numbers from dwindled from 2000 in 1960 to only three in recent years. Those last survivors, Sudan, his daughter Najin, and granddaughter Fatu, lived together at the Ol Pejeta Conservancy in Kenya. Each animal had physical issues making it difficult for them to breed, and now with Sudan gone, a new generation of northern white rhinos looks even less likely.

But there is one way the story of these animals doesn't end in extinction. Before Sudan died, researchers were able to save some of his genetic material, which means it's still possible for him to father offspring. Scientists may either use the sperm to artificially inseminate one of the surviving females (even though they're related) or, due to their age and ailments, fertilize one of their eggs and implant the embryo into a female of a similar subspecies, like the southern white rhino, using in vitro fertilization.

"We must take advantage of the unique situation in which cellular technologies are utilized for conservation of critically endangered species," Jan Stejskal, an official at the Dvur Kralove Zoo in the Czech Republic where Sudan lived until 2009, told AFP. "It may sound unbelievable, but thanks to the newly developed techniques even Sudan could still have an offspring."

Poaching has been a major contributor to the northern white rhino's decline over the past century. Rhinos are often hunted for their horns, which are believed to have medicinal properties in some Asian cultures. (Other people just view the horn as a sign of wealth and status). Procreating is the biggest issue threatening the northern white rhinoceros at the moment. If such poaching continues, other rhino species in the wild could end up in the same situation.

Watch How a Bioluminescence Expert Catches a Giant Squid

Giant squid have been the object of fascination for millennia; they may have even provided the origin for the legendary Nordic sea monsters known as the Kraken. But no one had captured them in their natural environment on video until 2012, when marine biologist and bioluminescence expert Edith Widder snagged the first-ever images off Japan's Ogasawara Islands [PDF]. Widder figured out that previous dives—which tended to bring down a ton of gear and bright lights—were scaring all the creatures away. (Slate compares it to "the equivalent of coming into a darkened theater and shining a spotlight at the audience.")

In this clip from BBC Earth Unplugged, Widder explains how the innovative camera-and-lure combo she devised, known as the Eye-in-the-Sea, finally accomplished the job by using red lights (which most deep-sea creatures can't see) and an electronic jellyfish (called the e-jelly) with a flashy light show just right to lure in predators like Architeuthis dux. "I've tried a bunch of different things over the years to try to be able to talk to the animals," Widder says in the video, "and with the e-jelly, I feel like I'm finally making some progress."
