A $150 Cat Feeder That Knows Each Cat by Sight

Petivity, owned by Purina, has launched its $150 Smart Feeder for Cats. A small camera recognizes each cat’s face, like a phone unlock, so up to five cats can share it without collars or microchips. The phone app records how much and how often each eats, with timed meals, remote feeding, and video check-ins.
