If you own a pet store, would you let visitors take photos of your pets?

For as long as they don't use a flash and they don't take the animals out of their cages, they can take as many pictures as they want. I will not allow them to use a flash because it might stress the animals. Aside from this, nobody knows what the effect of a flash will be on their eyes. For the same reason, I will also not allow them to take the animals out of their cages for pictures. Aside from the stress that this may cause, I also would not want to get into trouble just in case the animal bites or scratches them. I will only allow the pets to be taken out of their cages when the customers have shown genuine interest in them. This privilege will be limited to certain pets only.
