You could look into another mirror, but that would 1) make you lose this beautiful form and 2) probably change you into something worse like a bug or a mouse. So you're content to just lay there on the floor, feeling the untapped strength run through your veins.
Your ears involuntarily swivel to the right as you hear heavy footfalls. Someone is entering the hall of mirrors. You consider just laying there, letting them see you, and have them run out, but your new predatory instincts tell you to try something interesting. Getting to your paws, you sauntered behind a a wall, careful not to look into any mirrors, and wait.
A few moments later a twentysomething guy like you formerly were enters, looking around excitedly. You lick your maw and let your rough tongue slide over your fangs. You're about to reach up and pounce when a thought breaks through your haze. You don't want this guy to suffer endless transformations like you have. You'd better scare him out.
You, thankfully, note that he hasn't looked into any mirrors yet, seemingly preoccupied with something on his phone. You sauntered over, and give a low growl. The guy looks up, dropping his phone in the process, seeing you standing just a few feet away. "Nice...nice kitty." He mumbles, taking a step back. You give another growl and swipe at his leg with your massive paw. Yelling out, he turns tail and runs.
But he's running in the wrong direction, back towards the mirrors. Roaring in frustration, you give chase, trying to corral him towards the exit. It doesn't work, however, as he turns back to look at you, he runs face-first into a mirror and crashes to the ground. You come to a screeching halt and back up, roaring at him to get up and run.
But he doesn't. Instead of getting up and looking back at you, he looks up into the mirror. You growl in frustration. He's already changing.
