Like they say, self defense makes sense. Personal protection alarms are convenient to carry and catch the attention of people because they are loud and not easy to ignore. They come in various forms. An alarm that is the size of a key chain gives out such a loud sound that the assailant will be surprised and will go running away.

It has the function of the whistle but is more convenient because you can just press it with your hands. No need to put it in your mouth. A black cat self defense key chain can be a regular key chain but can double as protection. Some of these devices can be used by children. Just choose the kind that they can safely handle.
