A sensor controlled food and water system and method for pet animals. A collar of a pet animal can be attached to a sensor for selectively operating one or more bowls allocated to the pet animal. The bowl for storing the food and/or water can be linked with the sensor such that the lid of the bowl opens on detecting the presence of the pet animal near the bowl. Each animal can be provided with a collar having a sensor and a bowl linked with and/or which communicates wirelessly with the sensor (e.g., RFID tags). The lid of the bowl allocated to the animal opens when the pet is near the bowl and closes when the pet is at a distal or particular location from the bowl.
