Abstract: A device for indicating the presence of an electrical path on a pet accessory includes a first contact disposed on a probe, and a second contact disposed in a spaced apart arrangement relative to the first contact. An activation device is responsive to the presence of an electrical path or lack thereof between the first and second contacts. The activation device provides an indication of the state of the electrical path between the first and second contacts. The device preferably includes a pet dish and the probe extends into the dish to indicate a desired level for liquid in the dish, and the indication of state is performed by at least one of an audio message, a visual effect and a mechanical motion.
