The Call of the Wild

There are bugs to chase, cats to fight, insignificant things to be disturbed by... I must get outside. It is necessary. Why then won't this ridiculous Tall Guy let me out? So what if I take my time when I'm out. He should be waiting at the door to let me back in whenever I want to eat the food he gives me.
My strategy now is to hound him and Shorter Guy whenever they walk within 10 feet of an outside door. Eventually this will lead to their exasperation (it already has. I'm pretty sure Tall Guy (hereafter referred to as "The Gatekeeper") threw a total gym at me last night) and they'll let me out in the hopes that I get my comeuppance from neighborhood kids.
