Petlibro's Granary 2 feeder uses an AI camera to track multi-cat eating

Petlibro has launched the Granary 2, a new generation of smart feeders built around a built-in scale and aimed squarely at multi-cat households. According to TechCrunch, the central promise is simple: turn "how much did each cat eat, and when" into measurable data.

On the pricier models, the Granary 2 adds an AI camera as well. Working alongside the scale, the camera is meant to attribute food intake to individual cats rather than merely logging a total amount dispensed.

The hard problem in a multi-cat home has never been portion control. It is knowing which cat is overeating and which one is quietly eating less, and short of watching the bowl all day there is no reliable way to tell.

Weight shifts and appetite changes are often early signals of health problems, but humans are poor at tracking them consistently. Petlibro's approach combines hardware sensing with AI vision to turn that fuzzy observation into an automatic, long-running record — which is why the feeder is being described as a game changer for multi-cat homes.

There is a catch. TechCrunch notes that the most advanced health-monitoring features are not included in the purchase price; they require an additional subscription.

That subscription detail is the more interesting signal. AI features are steadily converting one-off hardware sales into recurring services, which means buyers now weigh long-term subscription costs alongside the sticker price of the device.

What to watch next is whether this class of AI pet hardware can turn raw data into genuinely actionable health guidance, and whether subscriptions quietly become the default shape of consumer AI hardware.
