I have photos of my cat when he got up and took a photo of your skin. If it happened, I heard a loud bang. I did it again right in the back and took another bang. Only when the flash, which you have to do something with the flash. I dont think im not hurt, meow, the cat or move. She sat there.Can someone tell me what it is?
