The short version
PETLIBRO's Granary is the best-selling automatic pet feeder on Amazon for a reason: a 5-liter freshness-locked hopper that holds weeks of dry kibble for a cat or a small-to-medium dog, precise portion control down to a single kibble, up to six meals per day, and a clog-prevention twin auger that reliably delivers food without jamming (the failure mode that made cheaper feeders infamous). The Granary comes in tiers — the basic button-programmed version works entirely offline, the Wi-Fi versions add app scheduling and remote feed-now, and the Granary Camera model adds an HD dual-way camera with infrared night vision so you can watch your cat eat while you're at work. For anyone with a cat that needs measured portions or a dog on a strict feeding schedule, it's a life-changing piece of pet tech.
Pros & cons
Pros
- 5-liter hopper — holds weeks of dry food
- Up to 6 scheduled meals per day
- Clog-prevention twin auger works with most kibble sizes
- Freshness-locked hopper keeps food fresh longer
- Runs on batteries (backup) plus wall power

Why people love it
Fill the hopper with dry food
Lift the freshness-locking lid, pour in dry kibble (up to 5 liters, which is weeks of food for most cats and small dogs), and close it. The seal keeps food from going stale.
Program feeding schedule
On the basic model, use the buttons on the front to set up to 6 meal times and portion sizes. On Wi-Fi models, use the PETLIBRO app on your phone for the same scheduling plus remote feed-now.
Set it and forget it
The twin-auger dispenser drops precise portions into the stainless bowl on schedule, and a voice recorder (basic models) or app notification (Wi-Fi models) alerts your pet at mealtime.
Who it's for
- Cat owners managing portion control
- Dog owners on strict feeding schedules
- Households where humans work long or irregular hours
- Traveling pet owners who want automated feeding while away
Why automatic feeders became essential for modern pet owners
The traditional 'fill a bowl in the morning, refill in the evening' feeding pattern works badly for a lot of pets, and modern life makes it worse. Cats are natural grazers who prefer 5-10 tiny meals throughout the day, but a full bowl encourages overeating and obesity — nearly 60% of US cats are now overweight or obese by veterinary standards. Dogs on scheduled feeding do better with predictable meal timing than with owner-timing that varies with commutes and social plans. And any owner with irregular work hours, occasional business travel, or a shift-work schedule has faced the specific stress of realizing they won't be home for their pet's dinner and needing to make a plan.
Automatic feeders solve all of this at once. Scheduled small meals eliminate grazing overeating for cats; predictable timing supports dogs' better digestion and reduces begging behavior; long-hopper capacity means a weekend trip doesn't require pet-sitter feeding logistics; and Wi-Fi models add the peace of mind of confirming feedings actually happened. For a cat or small dog household, a well-designed feeder like the Granary changes what pet ownership feels like — the daily-feeding decision becomes automatic infrastructure rather than a constant time management problem. The catch, historically, was that cheap automatic feeders were notorious for jamming, running out of battery, and dispensing wrong portions, which is why the reliable models like the Granary have earned such loyal reviews.
Setting up the PETLIBRO Granary for cats, dogs and multi-pet households
For a cat, the standard setup is 4-6 small meals per day (breakfast, mid-morning, lunch, mid-afternoon, dinner, and optionally a late-night meal). Portion sizes depend on your specific cat's daily calorie target — a healthy 10-lb adult cat typically eats about 200-250 calories per day, which for standard dry kibble is around 55-70 grams total, split across meals. Use the portion-size setting on the Granary to test what a single 'unit' of your kibble weighs (usually 1 unit ≈ 3-5g), then program the daily total across your chosen meal times. Start with your cat's current daily total and adjust gradually if weight management is the goal.
For dogs, most owners program 2-3 meals per day (morning, evening, optional midday) with larger portion sizes. Small dogs eat well from the Granary; very large dogs may find the standard bowl small and benefit from replacing the included bowl with a larger dish under the dispenser opening (the dispenser drops food onto the bowl area — as long as the food lands in a dish, it doesn't have to be the included one). For multi-pet households where one pet steals another's food, consider the Granary 2's RFID version (which only opens for the specific pet wearing the RFID collar tag) or split feeding by physical location — one feeder in a room the dominant pet can't access. The 5L capacity means for a single-cat household you refill roughly every 3-4 weeks; for a small-dog household roughly every 1-2 weeks. Pair with a Furbo 360 dog camera if you also want to see your pet eating from your phone — the two devices together automate feeding and monitoring for a household with irregular work hours.
Wi-Fi, camera and app features: what you actually use vs what sounds cool
The base Granary model works completely offline and does the core job (scheduled feeding, reliable dispensing) perfectly well. The Wi-Fi upgrade adds a few genuinely useful features and a few gimmicks — the honest breakdown of what's worth the extra $20-40. Actually useful: remote feed-now (you're stuck at work late and want to trigger dinner) is genuinely useful for irregular schedules. Feeding history (a log of every meal dispensed) is reassuring when you're worried a mechanical failure has skipped a feed. Push notifications when the hopper is low or the battery is dying prevent the specific nightmare of your pet not getting fed while you're away.
Gimmicks or lower-value features: the AI-analyzed pet mood/behavior features on newer models are novelty rather than actionable insights. The 'connect to smart-home hubs' features (Alexa, Google) are functionally identical to opening the app for the 5 seconds a manual command takes. The video-camera version is the one where the value is more subjective — for owners who miss their pet during the workday it's genuinely great to see them eating in real-time, and the 1080p HD with infrared night vision is a real upgrade over cheap pet cameras. For owners who wouldn't check the camera much, save the money. If a video-camera pet monitoring setup is what you actually want, a Furbo 360 dog camera or Wyze Cam v3 pointed at the feeder area might make more sense as a separate device. The right Granary tier is the one whose features you'll actually use — for most owners that's the mid-tier Wi-Fi model without the camera.

Is the PETLIBRO Granary worth it?
Yes — the PETLIBRO Granary is worth it, and it's the best-selling automatic pet feeder on Amazon for good reason. The 5L hopper holds weeks of dry food, the twin-auger dispenser is genuinely reliable (the failure mode that killed cheaper feeders' reputations), the freshness-locked hopper keeps kibble from going stale, and the up-to-6-meals-per-day scheduling handles cats needing portion control or dogs on strict schedules. The basic offline model at ~$70-80 does everything most owners need; step up to the Wi-Fi and camera models if you want remote scheduling or want to watch your pet eat while at work.
Which PETLIBRO Granary model should I buy?
Four main tiers: (1) Basic Button — offline, 5L, programs from the front buttons, ~$70-80, best for owners who don't want Wi-Fi setup. (2) Granary Wi-Fi — adds app scheduling, remote feed-now, feeding history, ~$90-100. (3) Granary Wi-Fi Camera — adds a 1080p HD dual-way camera with infrared night vision so you can watch your pet eat from your phone, ~$120-140. (4) Granary 2 series (2026 refresh) — adds advanced RFID pet-identification (only your pet's dish opens, keeping other pets or dogs out), smart activity tracking, and additional health features, ~$150+. For most single-pet households the Wi-Fi Camera is the sweet spot; the Granary 2 makes sense for multi-pet homes with a food-stealing dog or a pet on a prescription diet.
What kind of pet food does the PETLIBRO Granary dispense?
Dry kibble only. The Granary reliably handles kibble sizes from ~5mm to 15mm (which covers virtually all standard cat and dog kibble). Very tiny kibble (some kitten formulas) can sometimes double-drop, and very large or oddly-shaped kibble (some large-breed dog food) can occasionally jam the auger — check that your specific kibble is within the recommended size range. It does NOT work with wet food, semi-moist food, treats, or freeze-dried raw. For wet-food feeders, look at PETLIBRO's separate wet-food model (with ice packs and rotating chambers), which is a different product entirely.
How long does the PETLIBRO Granary battery last, and what if the power goes out?
The Granary can run on batteries alone (3 D-cell batteries, not included) for battery-only use — about 4-6 weeks of typical feeding schedules per set. Most owners plug it into wall power for daily use and leave batteries installed as a backup for power outages. This dual-power design is one of the reasons the Granary is more reliable than competitors: if your Wi-Fi drops, scheduled feedings still run; if the power goes out, batteries take over automatically; and you're never in a scenario where your cat doesn't get fed because a router rebooted.
PETLIBRO Granary vs Whisker Feeder-Robot vs PortionPro RX: which automatic feeder is best?
Three different tiers of the automatic-feeder market. PETLIBRO Granary is the mainstream best-value pick — reliable dispensing, generous capacity, cheap, well-supported. Whisker Feeder-Robot is the premium tier at 2-3x the price with a rotating carousel design that virtually eliminates jamming, better for very picky eaters or households with dogs that try to break in. PortionPro RX is a prescription-diet-focused feeder with RFID collar tags to prevent other pets from eating a specific pet's food, aimed at vets and pet owners managing serious medical diets. For 90% of households, PETLIBRO Granary is the right pick. Move up to Feeder-Robot if you've had jamming issues with cheaper feeders, or PortionPro RX if you're managing a specific pet's prescription diet in a multi-pet home.
Can the PETLIBRO Granary help my overweight cat lose weight?
Yes — controlled portion sizes on a schedule is exactly the diet strategy vets recommend for weight-loss cats, and the Granary makes it trivial to execute. Instead of leaving a full bowl out all day (which allows grazing and overeating), you program 4-6 small precise meals spread across the day. This satisfies the cat's hunger without exceeding daily calorie targets. Combined with switching to a lower-calorie weight-management food and gradually reducing portion sizes as directed by your vet, most owners report their cat losing weight steadily. The Granary Wi-Fi version's feeding-history tracking helps you verify the cat is actually eating each meal (not skipping meals then overeating later). Talk to your vet for specific caloric targets — the Granary handles the execution.
