Pigs are playful, friendly, sensitive, and intelligent animals. They’ve long been considered smarter than dogs, and they’re just as social as humans are! Much like people, pigs love music and playing ball, and they even enjoy getting massages.

On factory farms, pigs live in stressful, cramped, filthy conditions until they’re transported to the slaughterhouse. If given the choice, pigs would spend their days running around, playing with one another, and lying in the sun. Here are 10 surprising facts about pigs that’ll make you wonder how we could ever condemn them to such miserable living conditions and an early death—for food that we don’t need:

1. Pigs are chatty.

Pigs can make more than 20 different sounds for different situations, and they use these sounds to communicate with each other constantly. This means they use a specific oink, grunt, or squeal when trying to woo a mate or express hunger, for example. Most adorably, mother pigs sing to their babies while nursing.

2. They’re self-aware, too.

There are only a few other animal species who have passed the “mirror test.” This test, conducted by Professor Donald Broom at Cambridge University, revealed that pigs are able to use a mirror as a tool to find food that is not otherwise visible. This means that, unlike most other animals, pigs understand that mirrors are reflections, rather than windows.

3. You can play video games with them.

study by Dr. Stanley Curtis at Pennsylvania State University found that pigs can play—and enjoy—joystick-controlled video games and are capable of “abstract representation.” Hamlet and Omelette, the two pigs Curtis observed, would beg to be the first out of their pens in the morning so they could play the games.

4. You can teach them things.

Dr. Curtis didn’t just teach pigs how to play games. He also taught them to sit and jump on command as well as fetch a ball, a Frisbee, and a dumbbell when told. The piggies were able to tell the difference between the objects and remember the distinctions years after they initially learned them.

5. Pigs have awesome memories.

Suzanne Held at the University of Bristol found through her research that pigs are quite good at remembering where their food is stored. The pigs in her study were able to choose their food stashes from among eight different locations. They were also able to remember which stash had smaller treats, and when given the choice, they chose to go to the stash with larger treats.

6. They know how to trick each other.

Pigs are sneaky. They often learn to follow other pigs to find food. However, if a pig is aware that this is happening, he or she will sometimes create slick schemes to throw the other pig off the trail to avoid having to share the food.

7. They like to stay warm and cozy.

Much like most people, pigs are particular about the temperature. Another thing Dr. Curtis observed was that they’re capable of learning to adjust a thermostat. The pigs he observed would turn up the thermostat in the barn when they were cold and turn it back down when they were too warm.

8. Pigs like to keep it clean.

Snuggling Pigs

Though you might often say you’re “sweating like a pig,” this just isn’t true. Pigs don’t sweat! They do like to bathe frequently to keep cool, though. One guardian built a shower for her pigs that they learned to turn on and off by themselves.

9. A pig could save your life. 

Dirty Piglets

There are many recorded cases of a pig saving a human’s life. Pru, for instance, pulled her guardian out of a bog. Priscilla saved an 11-year-old boy from drowning. Then there’s LuLu, who squeezed through a doggie door and ran into the street to flag down a car when her guardian had a heart attack.

Pigs are also protective. Tunia chased away an intruder, and Mona held onto a burglary suspect’s leg while he was attempting to escape.

10. Pigs keep their eyes on the bright side.

Despite hardships, pigs remain optimistic. In his book, The Whole Hog, naturalist Lyall Watson stated: “I know of no other animals that are more consistently curious, more willing to explore new experiences, more ready to meet the world with open mouthed enthusiasm. Pigs, I have discovered, are incurable optimists and get a big kick out of just being.”

11. If you met a pig, you would fall in love.

At an agricultural program at one East Coast university, an instructor brought in eight pregnant pigs from a farm. After the moms gave birth, the students were instructed to auction off the mothers and their piglets for slaughter. As one student got to know the pigs, he learned how sensitive, intelligent, and loyal they are and couldn’t bear to sentence them to death. The student contacted Helga Tacreiter, who operates The Cow Sanctuary and has helped PETA with rescues over the years. With the help of PETA patron Sam Simon, Helga and the student persuaded the truck driver transporting the pigs to the slaughterhouse to turn around and take them to The Cow Sanctuary instead. The pigs are now loving their new home and finally living in peace.
