Petlibro Granary 2 Smart Feeder Uses AI Camera to Track Each Cat's Eating

Petlibro has launched the Granary 2, a smart pet feeder that pairs a built-in scale with an optional AI camera to log how much each cat eats and when. The pitch is aimed squarely at homes with more than one cat, where owners currently have no reliable way to tell whether one animal is overeating while another goes hungry. The feeder comes in several tiers, and the most detailed health tracking sits behind a paid subscription.

The core mechanism is straightforward. The scale weighs food as it leaves the hopper, giving owners a running record of portion sizes and feeding times rather than a single daily total. On the higher-priced models, the camera adds visual identification, which is what allows the system to attribute a given meal to a specific cat instead of treating the bowl as a shared resource. That distinction is the whole point: without it, a scale alone can tell you food disappeared, not who ate it.

Multi-cat monitoring has been a stubborn problem for the pet-tech category. Microchip-reading feeders from competitors address access control, letting only a designated animal near the bowl, but they generally do not produce the kind of longitudinal intake data that vets ask for when a cat is losing or gaining weight. Petlibro's approach flips that: the emphasis is on measurement and history, with the camera doing the identity work. For owners managing a cat with diabetes, thyroid issues or a prescribed diet, that record can matter more than the bowl itself.

The catch is the subscription. Petlibro is putting the fanciest health-monitoring features behind a recurring fee, which means the hardware price is not the full cost of the product over its lifetime. That is now standard practice across connected pet devices, from cameras to litter boxes, but it still changes the math for buyers comparing the Granary 2 against a one-time-purchase feeder. The company has not framed the subscription as optional for basic feeding, only for the deeper analytics.

What the Granary 2 does not solve is the harder question of what owners should do with the data. A log showing that one cat ate 20 percent less this week is only useful if it prompts a vet visit or a diet change, and Petlibro has not said how its app turns raw intake numbers into guidance. Whether the camera's identification holds up in a busy household, with cats eating at odd hours or sharing a bowl mid-meal, is the detail that will decide if the feature is a real tool or a novelty. Early buyers and independent testing will settle that faster than any spec sheet.
