Cats aren’t known to be patient, especially when their human servants are too slow to attend to their needs. That’s why many cats simply take matters into their own paws and stubbornly get what they want without human intervention.
In the above video, you can see a cat wanting to come back inside. Rather than wait for a slow and unreliable human to open the screen door, the cat decides to climb the screen and open the door itself.
Just watching this cat makes you realize that if cats had thumbs, they’d be holding the human race hostage and forcing us to work for them. Then again, if cats had thumbs, they would probably simply ignore the human race altogether except for the fact that humans can buy them cat food.
