Abstract: A portable chime system that is operable by a pet to alert the pet owner that the pet desires something such as to be let in or out of a building. The chime system includes a switch unit that may be placed on the ground or floor near a door and which may be activated by a pet applying pressure to the top of the unit. The switch unit is designed to avoid misfiring or nonfiring. The chime system also includes a remote chime unit that can be positioned in a different room or area than the switch unit. When the pet activates the switch unit, the switch unit sends a signal to the chime unit to sound a chime located within the chime unit.
