Oo! That's very interesting! It adds a kind of anxiety to finding animals. Tell you what, I'll absolutely think about it. If I ask you for help later when I start working on it, can I count on you to help me with details? Other then that, it's a pretty good idea! Also, if people don't like the idea, they can disable the feature in the configuration file or menu.
