"I can't take a picture of her buddy Lily up close, cause she's scared of the camera (even without flash !)"
The camera diaphragm closes it makes a noise similar to electromagnetic waves. If your camera has the sounds on for the aperture, you can hear that "click", when the diaphragm closes. But there are those sounds that humans can not hear, and just animals can, because they have a well-developed senses of hearing, that can notice higher levels of sounds. And many just might be scared by them!
