It's really startling. Maybe you prefer a parrot. A pet could be designed that would answer the door in a husky male voice and push a lever to dial 911 for police action. It's a bald-headed eagle programmed to return in 15 minutes to a small red patch pinned on the shoulder of any shirt, when taking this pet out for his daily flight. This could be done from an open window in your apartment, even on a rainy day.
Eagles have fantastic eyesight, far superior to human vision.
It might make you a lot of money. Delivery could be guaranteed within 12 weeks. Initial pet training would cost extra but would extend the guarantee from one year to three. Yes, points awarded for payment via American Express. Points also awarded when the pet accompanies you on a flight in Business Class.
