A presence detector mat for monitoring the presence of an animal within a defined area. The presence detector mat includes a variable parallel-plate capacitor separated by an elastic spacer, and a sensing mechanism. An electrical power source is provided to establish an electrical charge differential to the variable parallel-plate capacitor. The sensing mechanism is capable of detecting changes in the capacitance of the variable parallel-plate capacitor and transmitting a signal based upon such change in capacitance.
