Trackimo (available April 2014) is a very small GPS location device designed for both pets and humans. It costs $100 for the hardware and a 12-month mobile connection plan. You'll also get international GPS tracking (outside of US) for no extra charge. Depending on use, Trackimo lasts two to three days on a single charge and comes in a waterproof silicone case. One single "SOS" button will broadcast the wearer's location via app, email, or text.
