1. A presence detector mat for detecting and monitoring the presence of an animal within a defined area, said presence detector mat comprising:

  • a variable parallel-plate capacitor comprising first and second conductive planar members;

    an elastomeric spacing system disposed between said first and said second conductive planar members;

    a planar insulator coupled to said first conductive member;

    an electrical power source in electrical communication with said first and second conductive surfaces, said electrical power source configured to provide an electrical charge differential to said first and second conductive surfaces; and

    , a sensing mechanism comprising a controller responsive to variation in the capacitance of said variable parallel-plate capacitor;

    whereby detection by said controller provides an indication of the presence of an animal within the confines of the detector mat.
