These interspecies friendships prove that anybody can get along if they really put their minds to it.

1. PEANUT THE RAT AND RANJ THE CAT

When Maggie Szpot adopted two rats, she was worried about how Ranj, the stray cat she brought home in 2008, would react. But she didn't need to worry about Ranj hunting Peanut and Mocha—in fact, Peanut became enamored with the cat, following him around, cuddling with him, licking his face, and eating food out of his bowl alongside him. The two remained besties until Peanut died in 2010.

2. JOEJOE THE CAPYBARA AND HIS MANY FRIENDS

Capybaras are known for being very, very chill around other animals. They're regularly spotted hanging out happily with birds perched on their backs, puppies snuggled next to them, and monkeys climbing on top of them. (There's a whole Tumblr devoted to these capybara friendships.) JoeJoe the Capybara, perhaps social media's most famous capybara, is regularly seen cuddling with puppies, swimming with ducklings, and rolling around with the baby chicks he shares a home with in Arizona.

3. JUNIPER THE FOX AND MOOSE THE DOG

Juniper is a rescued fox who made fast friends with Moose, the Australian Shepherd mix with whom she shares a home. The two sleep together, eat together, and groom each other. Their owner, Jessika, often comes into a room to find Juniper sitting on top of Moose's head as the dog patiently allows himself to be used as a couch.

4. STRONG IMPACT THE RACEHORSE AND CHARLIE THE PIG

A lot of high-strung racehorses have companion animals that keep them calm. Strong Impact, a thoroughbred that raced for eight years, found a loyal companion in Charlie, a pig. The pig chose Strong Impact out of all the other horses in the barn, going stall to stall until he found an equine companion with whom he could cohabitate. According to a New York Times story on their friendship, they act like an old married couple and hate to be separated. (Strong Impact retired from racing in 2015 and is now part of an adoption program for retired racehorses.)

5. ANTHONY THE LION AND RILEY THE COYOTE

Anthony the lion and Riley the coyote met when both were one month old, recently rescued by Keepers of the Wild, a sanctuary for rescued exotic animals in Arizona. They immediately took a liking to each other, and their love was captured in a PBS Nature episode called "Animal Odd Couples" playing, grooming each other, and standing watch over each other during naptime. (Their segment starts at about 9:45.) Riley accompanied Anthony when he left the sanctuary for surgeries for a birth defect because the animals experienced such intense separation anxiety that one wouldn't eat without the other present. Sadly, Anthony passed away several years ago, and Riley now lives with another coyote at the sanctuary, Dominic.

6. SIMON COW-ELL AND LEONARDO THE TORTOISE

Simon the cow arrived at the WFFT Wildlife Rescue Center in Thailand in February 2016 after losing part of his hind leg. He was put in a temporary space in a field while he recovered from his injury, and was eventually supposed to join two other cows at the rescue in another enclosure. Instead, he formed an intense bond with the field's other resident, a giant tortoise named Leonardo that had been rescued when a Bangkok zoo closed in 2013. Simon nuzzles Leonardo, rests his head on his shell, and follows him around everywhere. They now live together permanently.

7. J'AIME THE RHINO AND JOEY THE LAMB

When J'aime came to the Rhino Orphanage in South Africa in March 2017, she was too young and small to be housed with her fellow rhinos. A few months later, though, she found a friend in Joey, a lamb who had been rejected by his mother and was brought to the sanctuary to be hand-raised. Joey was just a few days old at the time of their introduction, and he and J'aime quickly became best buds. They go for daily walks together and eat out of the same trough. Since May, they've also had another orphan in their little herd, a lamb named Penny.

8. LEO THE LION, BALOO THE BEAR, AND SHERE KHAN THE TIGER

When police made a drug raid on an Atlanta home 16 years ago, they made quite a discovery in the basement: one lion cub, one bear cub, and one tiger cub, which the drug dealer had been keeping as pets. The animals were in bad shape, but had formed a special bond. The trio was moved to the Noah's Ark Animal Sanctuary in Georgia, where they were nursed back to health. Baloo's injuries were the most serious; he had to undergo surgery to remove a harness that was so tight his flesh had begun to grow around it. "During Baloo's surgery was the only time the three brothers have ever been separated from one another, and Shere Khan and Leo became extremely agitated because of it, pacing and vocalizing for the lost member of their family of three to return," the sanctuary's website says. Baloo made a full recovery and the trio remained inseparable until 2016, when Leo passed away from liver disease. Baloo and Shere Khan continue to romp around their three-acre sanctuary.

9. CLEO THE CAT AND FORBI THE OWL

Brazilian biologist André Costa took in Forbi as a baby, and the owl became immediate friends with Cleo, Costa's cat (you can see a photo of little Forbi just hanging out on Cleo's side here). And they're still best buds!

10. BEA THE GIRAFFE AND WILMA THE OSTRICH

Both Bea and Wilma were born and raised in the 65-acre Serengeti Plain exhibit at Busch Gardens in Tampa, Florida. Assistant curator Jason Green told People that the duo "seem to enjoy spending time together. Bea likes to use her tongue to explore her surroundings, and Wilma isn't fazed by those very close encounters."

11. THEMBA THE ELEPHANT AND ALBERT THE SHEEP

Themba became an orphan at 6 months old when his mother died after falling down a cliff. The baby elephant was rescued by a team at Shamwari Rehabilitation Centre in South Africa, who put him in an enclosure with a sheep named Albert. "All hell broke loose," filmmaker Lyndal Davies told the Daily Mail in 2008. "Themba made a dash for the sheep and chased him around his watering hole." By the next morning, though, "Albert was clearly bored and started venturing out into the main enclosure. Themba wouldn't leave Albert's side and the two were seen exploring their enclosure together, with Themba's trunk resting on Albert's back. Ever since that moment Themba and Albert have been inseparable." According to wildlife director Johan Joubert, "Albert copies everything Themba does. In fact, they have almost the exact same diet. Albert is the first sheep I have ever seen eat a thorny acacia bush." You can watch a documentary about the pair above. Sadly, while the team at the center hoped to eventually introduce Themba back into the wild, the elephant died suddenly in 2010.

12. MUBI THE MONKEY AND IAIN AND DAISEY THE JACK RUSSELL PUPPIES

Mubi, an endangered drill monkey, was born at the Port Lympne Animal Park near Canterbury, Kent, but she was quickly rejected by her mother. So zookeeper Simon Jeffrey decided to hand-rear her. "During the day I take her to work and the team look after her at the enclosure where she can see her parents," he told the Daily Mail. "When I’ve finished working in the reserve, she comes home with me." There, she spends her time playing with two Jack Russell puppies, Iain and Daisey.

13. SAHARA THE CHEETAH AND ALEXA THE DOG

Cathryn Hilker, founder of the Cincinnati Zoo's Cat Ambassador Program, adopted the cheetah and the Anatolian Shepherd puppy when they were both two months old and raised them together. "They literally moved into my house and bonded with my rugs, my furniture, and each other," Hilker told Good Morning America. For a number of years, the pair toured schools in America raising awareness for the precarious position of the wild cheetah population. They even lived together at the zoo until 2010, when Alexa retired and went to live with a trainer.

14. CASSIE THE KITTEN AND MOSES THE CROW

In 1999, a tiny stray kitten appeared in Wally and Ann Collito's yard in North Attleboro, Massachusetts. The Collitos began feeding the kitten, but they weren’t the only ones: A crow also helped take care of the kitty, feeding her worms and bugs and protecting her from other animals. Eventually, the Collitos were able to coax Cassie inside, but the cat's incredible friendship with the crow didn't end there. The crow—whom they had named Moses—would peck at the door for Cassie every morning, and they'd spend the day hanging around together. The Collitos shot video and took photos of the two canoodling because they knew no one would believe them otherwise. This routine lasted for five years, until Moses stopped showing up, presumably because he had died.

15. OWEN THE HIPPO AND MZEE THE TORTOISE

When the waves of the devastating 2004 tsunami struck the coast of Kenya, a baby hippo was separated from his herd and became stranded on a coral reef. The next day, the hippo was rescued by the residents of the village of Malindi with fishing nets and taken to Haller Park Sanctuary, where the 660-pound animal—now named Owen—cozied up to a 130-year-old Aldabra tortoise named Mzee (maybe because the tortoise’s shape and color resembled an adult hippo). At first, the tortoise wasn't interested in this friendship, but eventually, they became inseparable, eating, wallowing in a pond, and even sleeping together. They lived in the same enclosure until 2007, when Mzee was removed from the enclosure because of safety concerns; Owen has since bonded with a female hippo named Cleo.

16. SABRE THE MINIHORSE AND ARROW THE GREAT DANE

Enjoy this video of Sabre, an 11-year-old miniature horse, hanging out with his friend Arrow, a 2.5-year-old Harlequin Great Dane, on a twin mattress.

17. JET THE DOLPHIN AND MIRI THE SEA LION

Though these two animals would normally be fierce competitors in the wild, at the Pet Porpoise Pool Marine Park in Coffs Harbour, Australia, they're the best of friends. Jet and Miri met as babies, and according to pool specialist Amy Carter, "They struck up a friendship really early on as they are the youngest. If Jet sees Miri going past he sticks his head out of the pool to say 'hi' and they make noises to each other."

18. PIPPIN THE DEER AND KATE THE GREAT DANE

In 2008, Isobel Springett rescued a fawn that had been abandoned by its mother in her yard, placing the tiny animal in the dog bed with her Great Dane, Kate. "She tucked her head under the dog's elbow," Springett told People. "Her whole demeanor changed. I knew she was a good dog, but I didn't expect her to mother the fawn." Though the deer eventually returned to the wild, she still visits, now with her own fawns. And though her babies won't get close, Pippin still comes in for a nose rub, which Kate returns. "There's a strong connection," Springett says, "but they have no idea it's a weird one."

19. TARRA THE ELEPHANT AND BELLA THE DOG

Get your tissues out for this one: For eight years, Tarra was best buds with Bella, a mutt who had wandered onto the grounds of Tennessee's Elephant Sanctuary. They had such a strong bond that Bella would let the elephant stroke her on her stomach with her foot, and when Bella had a spinal injury that confined her to the sanctuary office, Tarra "just stood outside the balcony—just stood there and waited," sanctuary co-founder Carol Buckley told CBS. "She was concerned about her friend. ... Bella knows she's not an elephant. Tarra knows she's not a dog. But that's not a problem for them."

But in 2011, Bella was found dead, probably of a coyote attack. "When I looked around and saw there was no signs of an attack here. No blood, no tuffs of hair, nothing," director of elephant husbandry, Steve Smith, told CBS. "And Tarra, on the underside of her trunk, had blood—as if she picked up the body. Tarra moved her."

20. ANONYMOUS CAT AND FOX

Fishermen in Lake Van, Turkey, spotted this wild cat and a fox playing, snuggling, and sharing fish together—and they've been at it for more than a year!

13 Fascinating Facts About Bees

iStock.com/florintt
iStock.com/florintt

Sure, you know that bees pollinate our crops and give us honey. But there's so much more to these buzzing insects than that.

1. Bee stings have some benefits.

A toxin in bee venom called melittin may prevent HIV. Melittin can kill HIV by poking holes into the virus's protective envelope. (Meanwhile, when melittin hitches a ride on certain nanoparticles, it will just bounce off normal cells and leave them unharmed.) Scientists at Washington University in St. Louis hope the toxin can be used in preventative gels.

Bee stings may also ease pain caused by rheumatoid arthritis. Researchers at the University of Sao Paulo found that molecules in bee venom increase your body's level of glucocorticoid, an anti-inflammatory hormone.

2. Bees work harder than you do.

During chillier seasons, worker bees can live for nine months. But in the summer, they rarely last longer than six weeks—they literally work themselves to death.

3. When bees change jobs, they change their brain chemistry.

Bees are hardwired to do certain jobs. Scout bees, which search for new sources of food, are wired for adventure. Soldier bees, discovered in 2012, work as security guards their whole life. One percent of all middle-aged bees become undertakers—a genetic brain pattern compels them to remove dead bees from the hive. But most amazingly, regular honeybees—which perform multiple jobs in their lifetime—will change their brain chemistry before taking up a new gig.

4. Their brains defy time.

When aging bees do jobs usually reserved for younger members, their brain stops aging. In fact, their brain ages in reverse. (Imagine if riding a tricycle didn't just make you feel young—it actually made your brain tick like a younger person's.) Scientists at Arizona State University believe the discovery can help us slow the onset of dementia.

5. Bees are changing medicine.

To reinforce their hives, bees use a resin from poplar and evergreen trees called propolis. It's basically beehive glue. Although bees use it as caulk, humans use it to fight off bacteria, viruses, and fungi. Research shows that propolis taken from a beehive may relieve cold sores, canker sores, herpes, sore throat, cavities, and even eczema.

6. Bees can recognize human faces.

Honeybees make out faces the same way we do. They take parts—like eyebrows, lips, and ears—and cobble them together to make out the whole face. It’s called "configural processing," and it might help computer scientists improve face recognition technology, The New York Times reports.

7. Bees have personalities

Even in beehives, there are workers and shirkers. Researchers at the University of Illinois found that not all bees are interchangeable drones. Some bees are thrill-seekers. Others are a bit more timid. A 2011 study even found that agitated honeybees can be pessimistic, showing that, to some extent, bees might have feelings.

8. They get buzzed from caffeine and cocaine.

Nature didn't intend for caffeine to be relegated to your morning pot of coffee. It's actually a plant defense chemical that shoos harmful insects away and lures pollinators in. Scientists at Newcastle University found that nectar laced with caffeine helps bees remember where the flower is, increasing the chances of a return visit.

While caffeine makes bees work better, cocaine turns them into big fat liars. Bees "dance" to communicate—a way of giving fellow bees directions to good food. But high honeybees exaggerate their moves and overemphasize the food's quality. They even exhibit withdrawal symptoms, helping scientists understand the nuances of addiction.

9. Bees have Viking-like navigation techniques.

Bees use the Sun as a compass. But when it's cloudy, there's a backup—they navigate by polarized light, using special photoreceptors to find the Sun's place in the sky. The Vikings may have used a similar system: On sunny days, they navigated with sundials, but on cloudy days, sunstones—chunks of calcite that act like a Polaroid filter—helped them stay on course.

10. Bees can solve hairy mathematical problems.

Pretend it's the weekend, and it's time to do errands. You have to visit six stores and they're all at six separate locations. What's the shortest distance you can travel while visiting all six? Mathematicians call this the "traveling salesman problem," and it can even stump some computers. But for bumblebees, it's a snap. Researchers at Royal Holloway University in London found that bumblebees fly the shortest route possible between flowers. So far, they're the only animals known to solve the problem.

11. Bees are nature's most economical builders.

In 36 BCE, Marcus Terentius Varro argued that honeycombs were the most practical structures around. Centuries later, Greek mathematician Pappus solidified the "honeycomb conjecture" by making the same claim. Almost 2000 years later, American mathematician Thomas Hales wrote a mathematical proof showing that, of all the possible structures, honeycombs use the least amount of wax. And not only are honeycombs the most efficient structures in nature—the walls meet at a precise 120-degree angle, a perfect hexagon.

12. Bees can help us catch serial killers.

Serial killers behave like bees. They commit their crimes close to home, but far enough away that the neighbors don't get suspicious. Similarly, bees collect pollen near their hive, but far enough that predators can't find the hive. To understand how this "buffer zone" works, scientists studied bee behavior and wrote up a few algorithms. Their findings improved computer models police use to find felons.

13. Bees are job creators.

The average American consumes roughly 1.51 pounds of honey each year. On top of that, the U.S. Department of Agriculture estimates that honeybees pollinate up to 80 percent of the country's insect crops—meaning bees pollinate over $15 billion worth of crops each year.

25 Benefits of Adopting a Rescue Dog

According to the ASPCA, 3.3 million dogs enter shelters each year in the United States. Although that number has gone down since 2011 (from 3.9 million) there are still millions of dogs waiting in shelters for a forever home. As May 20th is National Rescue Dog Day, here are 25 benefits of adopting a shelter dog.

1. Adopting a dog means you won't be supporting puppy mills.

If you go to a pet store or to a disreputable breeder to buy that adorable puppy, it's entirely possible that it's from a puppy mill, where dogs are kept in terrible conditions. By adopting a rescue, you can help lower the demand for puppies from puppy mills.

2. You can find almost any breed you want.

Is your heart set on a specific breed? There's a wide network of breed-specific rescues out there. Just spend a little time online and you can get the dog of your dreams without resorting to buying from puppy mills.

3. Shelter dogs are eager to follow your lead.

A 2016 study that appeared in Journal of Veterinary Behavior: Clinical Applications and Research analyzed problem solving in dogs in homes (what they called "pet dogs") versus shelter dogs. The researchers found that although pet dogs are better at following human pointing, shelter dogs "seem to be more socially driven to gaze and interact with humans" when compared with pet dogs, which they say is likely due to the shelter dogs' "generally limited and poor-quality contact with humans." But the researchers also pointed out that with increased human exposure, the shelter dogs were trainable.

4. A rescue dog might help you get a date.

According to Slate, one survey found that "82 percent of people [felt] more confident approaching an attractive person if they had their dog with them." Another study cited by Slate found that in the modern world of dating apps, people with dogs look more approachable and happy than those who are dogless.

5. You can share your audiobook collection with them.

There have been several studies on the best ways to calm dogs in kennels [PDF]. Classical music seems to work well, but a 2016 study found that compared to other "auditory conditions," kenneled dogs were more relaxed while audiobooks were playing. Cesar Milan then did his own tests and found that 76 percent of his volunteer dogs were more relaxed at home while listening to audiobooks—and teamed up with Audible to create a specialized audiobook service. Just be careful: soon your rescue pup will be better read than you.

6. Rescue dogs can transform in dramatic ways in a forever home.

Thanks to those heart-wrenching ASPCA/Sarah McLachlan commercials, everyone is familiar with how sad a dog can appear in a shelter. But once adopted, dogs' attitudes can change dramatically. In 2008, Italian researchers published a paper about a shelter dog named Daisy that they placed into a facility for people suffering from Alzheimer’s disease. Although in the shelter Daisy had groomed so much that she developed a skin lesion, in the six months that she lived at the facility, her over-grooming lessened, she was healthy, and she "displayed no aggressive or sexual behavior, even when in heat." And the calming effect seemed to go both ways: the researchers reported, the people in the facility experienced "many positive effects of Daisy's presence."

7. Shelter pets come with benefits.

Whether you get your pet at a breed-specific rescue or from a normal shelter, you'll often have access to resources about your fuzzy new family member, and maybe even classes on how best to take care of them.

8. Shelter dogs are typically up-to-date on all their shots.

Depending on the shelter, shelter dogs may already be vaccinated and microchipped (or the shelter will perform these services for a small fee)—which means you can get straight to cuddling your new pet instead of making vet appointments.

9. Shelter dogs may also already be spayed or neutered.

More than half of states have laws requiring "releasing agencies" (a.k.a. shelters) to spay or neuter dogs they adopt out. While the pet sometimes isn't fixed until you adopt it, frequently it's already been spayed or neutered. Check with your local adoption center.

10. By adopting a dog, you're helping to keep the unwanted pet population down.

If you happen to adopt a dog that isn't fixed, you can still help prevent pet overpopulation (especially in the wild) by keeping it in the house and away from other unfixed dogs of the opposite sex. (But seriously, get your pets fixed!)

11. Rescue dogs may be easier to housetrain.

Many adult shelter dogs are already housebroken when you adopt them. But because the dog may have a history that prevented such training (such as never being allowed inside the house), you shouldn't go in expecting a house-trained pet. If your new pupper isn't house-trained, there are resources out there that can help you reach that goal; many say that adult dogs have an easier time getting the hang of it.

12. Adopt and older dog and you can skip the puppy stage.

Yes, puppies are adorable. They're also full of energy and require a lot of time, training, attention, and patience. It can be tough to fit an energetic puppy into a hectic life. Adopting an older dog from a shelter allows you to skip the puppy stage altogether, which can mean an easier transition from not having a pet to being a pet owner. It also (hopefully) means you may avoid having your slippers, running shoes, pillows, furniture, and doors gnawed on by sharp little puppy teeth.

13. If you adopt an older dog, you'll have a better idea of their temperament.

An analysis of many studies found that the "personality" of an adult dog is fairly consistent. Puppies, on the other hand, can change personality a fair amount, especially when it comes to "responsiveness to training, fearfulness, and sociability." So by getting an adult dog, you have a better idea of what the animal's personality is truly like.

14. A shelter can help match you with a dog that best reflects your personality.

Because adult dogs are generally more fixed in their personalities, many adoption centers have matching programs that help the process of pairing dog and human. The ASPCA claims the programs have dramatically improved successful adoptions at some shelters.

15. You'll feel more involved in the community.

According to a 2013 study, dog owners over 50 who walked their dogs felt a higher sense of community. So adopting a dog can help you connect to your neighbors.

16. A dog can improve your health.

A study of Mexican dog owners versus non-dog owners found that the dog owners felt that they were healthier: "Compared to non–dog owners, the dog owners' scores were significantly lower for psychosomatic symptoms and stress and were higher for general health, vitality, emotional role, absence of bodily pain, social functioning, and mental health."

17. Your kids will play more if you have a dog.

It's not just adults who experience health benefits from having a dog; another study found that child dog walkers played outside more and were more likely to walk in the neighborhood.

18. Adopting a pet helps small wild animals.

As one of the most common predators in human areas, dogs can easily do great harm to local wildlife. By keeping dogs out of the wild (whether that's the city or the countryside), you can help reduce the numbers of truly wild animals that are preyed upon by what are supposed to be pets.

19. Adopting a dog can limit the spread of disease.

Feral dogs can also have disastrous effects on wild animals in regards to disease. For instance, the black-footed ferret was nearly driven to extinction by canine distemper. By keeping dogs out of the environment and up-to-date on all their necessary shots and vaccinations, adopters help many other animals, too.

20. You could have a movie star on your hands.

A surprising number of actual canine movie stars came from shelters. The original Benji was adopted from a shelter; Rudy, one of the 22 dogs that played Marley in the film Marley and Me, was just 24 hours away from being put down before he was rescued; and Spike, the star of Old Yeller, was adopted from Van Nuys Animal Shelter, supposedly for $3.

21. A rescue dog might have experience living in a home, making the move from shelter to your home an easier transition.

Some shelters have foster programs, where the dog is sent out to live with a volunteer in an actual house. Not only does this give the dog a chance to be away from the shelter, but it gives the humans looking after the pup a chance to see how the dog reacts in a less controlled environment—hopefully making the future forever home transition easier.

22. Even volunteering to foster has its benefits.

If you're not quite ready to adopt, consider fostering, which has a number of benefits for you and for the dogs you're housing. According to one researcher, overweight participants in a "loaner" dog walking program lost an average of 14 pounds because they felt "the dogs need us to walk them." Other participants in a community dog walking program were inspired to increase their exercise even when they weren't walking dogs.

23. You can help shelters modernize.

Shelters across the country are modernizing their facilities—which can sometimes be a very expensive prospect. The adoption fee you pay to the shelter to take your dog home will help the facility get the resources to give future dogs a better shelter experience.

24. By adopting a dog, you're saving at least one life.

By giving a dog in a shelter a second chance, you can make sure it has a great life.

25. In reality, you're probably saving more than one life.

By adopting a dog, you open up a space in the shelter that can be filled by another future pet. And by supporting your local shelter, you help their mission to save many more.

But remember, a pet of any kind is a massive commitment. Some estimate that "more than 20 percent of people who leave dogs in shelters adopted them from a shelter." And studies have found that much of the problem is people not knowing what they're getting into. So make sure that you have the time and energy to devote to a pet, and do your research before adopting.
