Pets can hear phone cameras

The conspiracy I’m convinced is real is that our pets can hear when we turn on the camera on our phone. Every time my cat is doing something adorable, the second I pull out my phone to record or take a photo she stops. It doesn’t matter how quietly or discreetly I do it, they just seem to automatically know. My thought, is that they must be able to hear or feel some sort of noise/vibration that we don’t notice. Why else would I have such a hard time getting adorable cat photos?
