We humans think we are so much smarter than cats. But cats have just managed to fool humans into thinking so. They trained us to feed them, shelter them, and clean up their mess for nothing in return but a little entertainment. And when we aren't looking, they do exactly as they please. Who am I kidding? They do exactly as they please even when we are looking!
Redditor foflexity was eating outside with his family, and the cat was annoying, so he put the cat in the shed. This tomcat has stolen food before. It didn't take long for the cat to escape. Putting the cat back into the shed was not working, so foflexity set up a camera to see how the cat was getting out.
See? cats don't need opposable thumbs to conquer the world. They just need to be smart enough to figure out how a mechanism works. It looks like foflexity's cat is that smart. -via Laughing Squid
