Menagerie is the newest pet craze from the Acme Corporation. The robotic animals genetically bind to their owners. Only three easy steps to link: 1) Put a drop of fluid (saliva or blood) in its mouth 2) Wait for 24 hours 3) Tell your dreams and fears to your forever friend. By the way, genetic binding is an imperfect science. 15,000 words, give or take a character or two.
