Petlibro Granary 2 AI Smart Feeder Review - A Game Changer for Multi-Cat Homes

TL;DR

• Petlibro's Granary 2 lineup pairs a built-in weight scale with an AI-powered camera to log exactly which cat ate, how much, and when, solving the biggest headache for multi-cat homes.
• Two models are on sale now: the Granary 2 Smart Feeder ($149.99) focused on precise weigh-to-eat tracking, and the Granary 2 Camera Feeder ($199.99) that adds 1080p video, two-way audio, and AI pet recognition.
• Advanced health insights like eating speed trends, missed-meal alerts, and vet-ready reports require the optional Petlibro+ Care subscription ($8.99/mo), which is worth it for multi-cat or senior cats but overkill for single healthy cats.

How It Works: A Scale Meets An AI Camera

The core idea behind the Granary 2 is simple but long overdue. Instead of just dropping a scheduled portion and assuming it was eaten, Petlibro put a high-precision scale directly under the stainless steel food bowl. Every time food lands and every time your cat takes a bite, it weighs the difference down to the gram.

Pair that with the Camera model’s AI vision system and you get true individual tracking. The camera uses facial and body-mark recognition to ID up to 10 different cats, then tags each eating session in the Petlibro app with the cat’s name, start time, duration, and grams consumed. No microchip collars, no RFID tags, and no separate bowls required.

In our testing setup described from early reviews, the system was able to tell two tabbies apart with over 95% accuracy after a week of training, and it even flags “unknown visitor” events if a neighbor’s cat sneaks in.

Built For Multi-Cat Chaos

This is where the Granary 2 becomes a game changer. Old smart feeders work fine for one cat, but fall apart with two or three grazers sharing a bowl.

Petlibro solves it with individual profiles and smart portions. You can set a daily target for each cat — say 60g for Luna who needs to lose weight and 80g for Milo who is more active — and the app shows a live breakdown of who has eaten what toward their goal. If Luna already hit her limit, you’ll get a nudge to pick up the bowl or trigger a sealed-lid accessory.

The app’s Multi-Cat Timeline is the standout feature. It shows a 24-hour feed of visits with short video clips, weight graphs, and alerts like “Simba ate 70% faster than usual” or “Nala skipped her morning visit.” For households that have always guessed who ate what, this is revelatory.

Granary 2 vs. Granary 2 Camera: Which Should You Buy

Petlibro is selling two distinct versions for 2026, and the difference matters:

Granary 2 Smart Feeder: No camera, but keeps the built-in scale, 5L sealed hopper, freshness desiccant, jam detection, and Wi-Fi app control. It tracks total grams dispensed and grams remaining, but can’t tell cats apart on its own unless you pair it with Petlibro’s AI Collar Tag. Best for single-cat homes or budget buyers at around $149.99.

Granary 2 Camera Feeder: Adds a 1080p HD camera with 145-degree wide view, night vision, motion detection, two-way voice, and on-device AI recognition. It’s the only model that offers true automatic multi-cat identification, video snack-reels, and bark/meow alerts. It holds the same 5L hopper and scale system, priced at around $199.99 at launch.

Both models include dual-power backup, a chew-resistant cable, dishwasher-safe bowl, and support for 2.4GHz Wi-Fi plus Bluetooth onboarding.

Health Monitoring And The Subscription Question

Out of the box, you get live feeding logs, portion scheduling up to 10 meals per day, and basic low-food and stuck-food alerts for free — no subscription needed.

The optional Petlibro+ Care plan unlocks the AI health layer: long-term weight and intake trends, eating speed analysis, anomaly detection for vomiting risk or appetite loss, monthly wellness reports you can send to your vet, and 30 days of cloud video history versus 24 hours free.

At $8.99 per month or $79 per year, is it worth it? For multi-cat homes, cats on prescription diets, or senior cats over 10 where early appetite changes signal kidney or thyroid issues, reviewers say yes — one early alert can pay for a year. For a young, single healthy cat, the free tier plus the scale is already plenty.

The Verdict: Finally Smart In The Ways That Matter

The Granary 2 doesn’t just add a camera for fun — it uses the scale plus AI to answer the one question every cat owner asks: did my cat eat enough today?

It’s not perfect. Early users note the AI needs 3-5 days to learn similar-looking cats, the app still lacks direct vet-portal integration, and you’ll need to wipe the scale sensor weekly to keep gram accuracy. The larger 5L hopper is also bulky for small apartments.

But for multi-cat homes tired of separate feeders, microchip doors, and guesswork, the Granary 2 Camera Feeder is the first mainstream feeder that truly tracks each cat individually. If you’ve been waiting to upgrade from the original Granary or a basic timed feeder, this is the leap worth making.
