Build a microchip-controlled feeding enclosure that can authorize multiple cats, protect one or more food compartments, and enforce configurable feeding windows. The first version can be a retrofit enclosure compatible with common bowls and automatic feeders, reducing the cost and complexity of manufacturing a complete feeder. Optional weight sensing can help owners identify missed meals or unusual consumption.

More cats already have implanted microchips that can serve as collar-free identifiers, while buyers are actively comparing expensive single-cat feeders and waiting for reliable recognition alternatives. A retrofit design offers a practical entry point before developing a fully integrated appliance.
