Redditor Elphaba16 has several pets, including a male cat named Kevin Jones and a female dog named Joule. She set up a camera to see what goes in the home when the humans are at work, and found out that Kevin and Joule have a special relationship. They don't favor each other much when people are home, but when the house is empty, they enjoy cuddling and napping together on the sofa. There are more videos and still images of these two at Instagram. -via Laughing Squid
People who are born Year of the Tiger and Year of the Dog (Chinese Astrology) are natural best friends. And I've observed it for over 10 years to verify it (I didn't just blindly believe chinese astrology I asked people their birthdate and watched their interactions).
Oh and I'm not saying this as a brag. It's actually super frustrating being an American who knows Chinese Astrology is 100% true but most people think it's meaningless.
