Mobile Alert and Security System

A safety alert system for a vehicle has a computerized monitoring apparatus storing a pre-programmed telephone number for a specific cellular telephone, a plurality of sensors coupled to the computerized monitoring apparatus, sensing at least on/off status of vehicle ignition system, presence or absence of a person in a driver's seat of the vehicle, and presence of a person or another animal in a location in the vehicle other than the driver's seat, and wireless transmission circuitry adapted to send an alert to a cellular telephone. The computerized monitoring apparatus senses that vehicle ignition is on, a person is in the driver's seat, and there is a person or another animal in a location in the vehicle other than the driver's seat, then senses that the ignition is switched off, then senses that there is no person in the driver's seat, and then sends an alert to the cellular telephone.
