When I was in my early twenties I had a rabbit, a sixteen-pound French Lop that had free rein of parts of the house and succeeded in both equally fascinating and terrifying every houseguest I ever had. From her ability to clear a seven-foot gate to her skill in severing any cord or wire ever laid out in her path, Gwendolyn was much more akin to a troublesome toddler trapped in a four-legged body the size of a Corgi than what the average person pictures when they think of a pet rabbit. Out of all her tricks and quirks, the one that still echoes loudest in my mind years later was her unfailing habit of excitedly charging any time she heard a sound reminiscent of pills shaking in a bottle. She would come immediately running at the sound, often at top-speed, obsessively expecting a treat. While it delighted friends and family, it was an accidental behavior that was an unintended consequence of my own naïveté in terms of how strongly animals can form associations with sounds.
