See if you have ear powers

You turn around to scan the room with your gleamy yellow eyes. By deceptively simple logic you deduct that your cat ears must also contain weird powers.

Sophie: "I'll try to focus real hard, and see if I can make magic happen."

At first you think about clenching your hands into fists and grunting with effort. However, this isn't necessary at all. By the smallest twitch of your ears, every single object in your immediate area of vision begins to levitate. Despite the already surreal events of today, your jaw is left hanging in disbelief.

Sophie: "Holy- Holy balls!"

You strut around the room, surveying your furniture and possessions that have all lost their grasp on gravity. Then you think to try other things. With another little flap of your ears, you manage to change the sofa into a different color and make. A similar move lets you double the size and resolution of your TV, and split your coffee table into two smaller replicas.

It's obvious to you that these powers work however you want them to, and your ears serve to activate them. You wonder what kind of limits these powers have, if any?
