A low voltage battery powered door mat alarm having an alarm buzzer circuit with mat circuit contact closure by the weight of the pet such as a cat walking across the mat to or from an animal pet door. This activates the buzzer to indicate generally that the pet is approaching the door to go out or has just returned through the pet door with the mat positioned just inside the door so the pet must pass over the mat to go out or come in through the door.
