I suspect all domesticated animals, and many non-domesticated animals that live in close human contact, also display such behaviors. My horses respond to hearing the door of the house close early in the morning, knowing that grain is soon on the way. My cattle hear the tractor start and start moving in their slow fashion to the hay feeder. If I holler in a particular way that often presages grain, they'll stampede to the location.
