PETLIBRO Granary 2 Vision Review: A Smart Feeder That Finally Knows Which Cat Is Eating

I work with multi-cat households, and there is one problem that comes up in almost every consultation: you cannot manage what you cannot measure. When three cats share a bowl, nobody knows who is eating what. The cat quietly losing weight looks fine until it does not. The cat on a prescription diet eats the other cat’s food. And the first sign of kidney disease, hyperthyroidism or dental pain — a change in how much a specific animal eats — is invisible.

Microchip feeders solved part of this years ago, but they are fiddly, and collar-based systems assume your cat tolerates a collar. The PETLIBRO Granary 2 Vision takes a different route: gram-level intake tracking, an HD camera, and AI recognition for up to 10 cats with no collar needed, at $189.99. If it works as described, that is a meaningful step forward.

Specifications at a glance

At $189.99 the Vision sits $60 above the camera-free Granary 2, and that gap is entirely about identification and monitoring. Current pricing, the Duo version and the multi-device bundles are on the official PETLIBRO store.

What the Granary 2 Vision gets right

Collar-free identification removes the main barrier

Every previous generation of selective feeder required something on the cat: a microchip scan at close range, or an RFID tag on a collar. Both work, but both have real-world failure modes — cats that slip collars, cats that will not put their head far enough into a hooded feeder, and rescue cats who are simply not going to accept a new object around their neck. Visual recognition sidesteps all of that, and for a nervous or newly adopted animal it is a genuine welfare improvement.

Gram-level tracking is clinically useful data

This is the feature that matters most and gets discussed least. A vet asking "has her appetite changed?" is currently asking you to guess. A feeder that logs grams consumed per cat per meal turns that guess into a chart. For any cat with a chronic condition, or any senior cat, that record is worth more than the convenience of automated feeding.

Ten cats is a serious capacity

Most selective feeders handle two or three animals. Supporting up to ten puts this within reach of foster homes, small rescues and genuinely large households — exactly the situations where individual monitoring is hardest and matters most.

The camera does double duty

HD meal monitoring lets you see whether a cat is actually eating or just standing at the bowl, whether they are chewing on one side, whether someone is being guarded away from the feeder. Those are behavioural observations you would otherwise only catch by luck.

Three things I would change

1. Visual recognition has to cope with cats that look alike

AI identification by appearance is impressive but it is pattern matching, and two black cats, or two similarly marked tabby siblings, are exactly the hard case. PETLIBRO does not publish an accuracy figure for the recognition system on the listing I read. If your monitoring plan depends on distinguishing two similar cats — which is often precisely why people buy these — ask for accuracy data before you rely on it clinically.

2. It monitors, but a shared bowl is still a shared bowl

Recognition and tracking are not the same as exclusion. A feeder that identifies who is eating still needs a physical mechanism to stop the wrong cat eating, and the listing emphasises insight and personalised feeding rather than lockout. If you need to guarantee that a cat on a prescription diet cannot access the other cat’s food, verify exactly what this model blocks versus what it merely records.

3. A camera in your home is a camera in your home

Cloud-connected cameras carry privacy and subscription considerations that a dumb feeder does not. Check what is stored, where, for how long, and whether any features require an ongoing subscription. It is also a device with a power dependency — a mains-powered feeder that stops working in an outage is a different risk profile from a gravity feeder, and worth planning around if you travel.

Who should buy it — and who should skip it

Buy it if

• You have multiple cats and no reliable idea who is eating how much — especially if one is senior, chronically ill, or losing weight.
• Collar or microchip feeders have failed for you because your cat will not tolerate them.
• You want intake data you can actually show a vet rather than an impression.

Skip it if

• You have one cat and just want scheduled feeding — the Granary 2 at $129.99 does that for less.
• You need hard dietary separation rather than monitoring; confirm the lockout behaviour first.
• You are not comfortable with an internet-connected camera in a living space.

The verdict

The Granary 2 Vision is solving the right problem. Collar-free identification and per-cat gram-level intake logging turn feeding from a chore into a health record, and for multi-cat and foster households that is worth the $60 premium over the standard Granary 2. What I would want before recommending it unreservedly is a published recognition accuracy figure and a clear statement of what the feeder physically prevents rather than simply observes. Ask PETLIBRO both questions. If the answers hold up, this is the most interesting thing to happen to automated feeding in years.
