Our verdict: a Petlibro automatic feeder suits owners who want timed, portioned dry-food meals with no subscription, as long as they weigh one portion once and keep kibble within 2 to 15 mm. Saved schedules keep running when the Wi-Fi drops, and the right model depends on your household need.
This Petlibro automatic feeder review is an expert analysis of the manufacturer's published specifications, the Chewy listing, and veterinary guidance. No hands-on test was performed by WebVet: WebVet did not obtain the product, and no manufacturer or retailer paid for or reviewed this article.
Petlibro automatic feeder at a glance: what it is and who it suits
Schedules saved on a Petlibro feeder keep running without the network, and the Granary 2 adds a backup battery rated for up to 24 hours. A portion is measured by volume, so check it once on a scale. Jams are linked to large or oddly shaped kibble, and each household need has its own model.
- 1For a busy household, a Petlibro feeder serves timed, portioned dry-food meals, up to 10 a day on the Granary 2, and keeps its saved schedule if the Wi-Fi drops.
- 2Pick the model by pet: a Granary for dry food, the Vision Duo for two pets sharing, the One RFID for one pet on its own diet, and the Polar for wet food.
- 3One portion on the Granary camera feeder is 20 ml, about 1/12 cup, and its weight changes with the kibble, so weigh one meal before trusting it.
- 4Keep kibble between 2 and 15 mm across. No subscription is needed to run the feeder.
This review centers on the Petlibro Granary WIFI 2.4g & 5G Automatic Two Cat & Dog Feeder, listed at $99.99 on Chewy when we checked in October 2026. Chewy's listing pitches it for keeping a dog's or cat's meals on time while you are away, or for midnight feedings.

What vets say about scheduled meals:
- Merck: the Merck Veterinary Manual says leaving food out all day for a cat, known as free-choice feeding, is not recommended because it can lead to overeating, and that overfeeding can lead to obesity and a shorter life. Most cats, Merck adds, do well on two meals a day.
- VCA: VCA Animal Hospitals calls at least two meals a day the most common recommendation and notes that some cats do better with more. Adult cats can also graze, VCA says, if the day's portion is measured out each day, which is the job a portioned feeder does.
Timed meals for cats or dogs, with app control on 2.4 GHz or 5 GHz Wi-Fi and no subscription required.

Is PETLIBRO a good brand?
We found no veterinary or independent rating of Petlibro as a brand, so a fair answer rests on what the company documents and what has been reported. The documented strengths are real: up to 10 meals a day, schedules that survive a Wi-Fi drop, a backup battery on the Granary 2, and no required subscription.
The reported weakness is an outage that Cybernews covered under the headline "Pet parents furious as smart feeders go offline." If you are still comparing brands rather than Petlibro models, our guide to the best automatic cat feeders covers the wider field.
Which Petlibro feeder to buy: Granary, Air, camera, One RFID, and wet food models
Petlibro sells feeders for very different homes, so the choice comes down to household need: how many pets eat from the feeder, whether they eat dry or wet food, whether you want a camera, and whether one pet needs a diet of its own.
The Petlibro Granary WIFI 2.4g & 5G Automatic Two Cat & Dog Feeder is the Granary that Chewy sells. Check what you are getting before you buy:
- Chewy listing: it cites a dual power supply but gives no battery runtime, and it does not name the Granary 2.
- Granary 2, per Petlibro's site: a 5 L dry-food feeder on 2.4 GHz and 5 GHz Wi-Fi with a 24-hour rechargeable backup battery, listed at $129.99 in October 2026.
- At checkout: confirm the model before counting on Granary 2 features such as the backup battery.
On a tighter budget, the Petlibro Air Wi-Fi Automatic Dog & Cat Feeder, Black, 2-L is the step down:
- Price: listed at $69.99 on Chewy when we checked in October 2026.
- Schedule: its listing says you can program up to six pre-portioned meals a day from the 2 L hopper.
- Power: the listing cites a 180-day battery life with no cables, but gives no portion size.
- Lid and buttons: the top lid has a press-to-lock button, and the control panel can be covered to stop spilled food or a curious pet from pressing buttons.

The rest of the lineup, priced as Petlibro listed it on its site in October 2026, covers narrower needs:
- Camera check-ins: the Granary camera feeder, listed at $139.99, holds 5 liters of dry food and has a 1080p camera with a 145-degree lens and night vision. The Granary 2 Vision, listed at $189.99, steps up to a 1080p AI camera and a 48-hour backup.
- Two pets sharing one feeder: the Granary 2 Vision Duo, listed at $199.99, offers dual-bowl feeding with multi-pet recognition. For other two-cat setups, see our guide to the best automatic feeder for multiple cats.
- One pet on its own diet: the One RFID, listed at $149.99, holds 3 liters (about 13 cups) and unlocks only for its own collar tag. It does not read a microchip or another brand's tag and syncs with one tag; feeders that read a chip are in our best microchip pet feeders roundup.
- Wet food: the Polar (PLAF109), listed at $169.99, serves 3 meals of up to 6.76 oz (200 ml) each and uses thermoelectric cooling instead of ice packs.
Both the Granary and Air listings name dogs as well as cats. If you are weighing dog feeders beyond Petlibro, our best automatic dog feeders guide compares the field.

Our verdict on the Petlibro Granary WIFI 2.4g & 5G Automatic Two Cat & Dog Feeder: listed at $99.99 on Chewy in October 2026, it is a lower-priced way into the Granary line than the Granary 2, which Petlibro listed at $129.99.
Before buying, confirm the model at checkout, weigh one portion on a gram scale, and keep kibble within 2 to 15 mm.
Buy a Petlibro if:
- You want timed, portioned dry-food meals with no subscription required.
- You want the feeding schedule to keep running if the Wi-Fi drops, with up to 24 hours of battery backup on the Granary 2.
- Your kibble falls within Petlibro's 2 to 15 mm range.
- You want a feeder with no cables: the Air's Chewy listing cites a 180-day battery life.
- Your household need is one of the specialist setups: a camera, two bowls, a tag-locked lid, or cooled wet food.
Look elsewhere if:
- Your pet's kibble comes in large square or crescent-shaped pieces, which Petlibro says jam more easily.
- You need a feeder that reads your pet's microchip rather than a collar tag.
- You want a bigger hopper than the Air's 2 L for the same Chewy listing price ($69.99 in October 2026), such as the 20-cup OneIsAll.
Portion size and accuracy: what one portion really means
Petlibro measures a portion by volume, not weight, so the same setting can deliver a different amount of food when the kibble changes. On the Granary camera feeder, one portion is 20 ml, about 1/12 cup.
How much does PETLIBRO automatic feeder dispense?
The Granary camera feeder dispenses 1 to 50 portions of 20 ml per meal, so one meal runs from about 1/12 cup to a little over 4 cups, with up to 10 meals a day. By weight, Petlibro's feeder FAQ puts one portion at about 10 g, give or take 4 g.
That 4 g swing is why one check on a scale matters. Petlibro's Granary 2 FAQ says kibble size and density change each portion's weight, and its Granary 2 page says the bowl scale measures food to within 1 g. AAHA guidance recommends weighing food on a gram scale rather than by the cup.

Your veterinarian is the right source for the daily amount; for a growing dog, our guide on how much to feed a puppy walks through it. Merck says kittens under 4 months should eat 3 to 4 times a day, which fits easily inside a 10-meal schedule.
How 20 ml portions add up on the Granary camera feeder:
- 3 portions: 60 ml, about 1/4 cup.
- 12 portions: 240 ml, about 1 cup.
- 12 portions by weight: about 72 g if your kibble runs near 6 g a portion, or about 168 g near 14 g, the two ends of Petlibro's stated range.
The same weigh-once check applies to any app-run feeder. The Catit Pixi Smart Cat Feeder, which Chewy listed at $111.80 in October 2026, sets meal times and adjusts portions through the PIXI app, according to its listing.
To program a Petlibro feeding schedule by weight:
- Weigh the day's food on a gram scale.
- Let the feeder serve one meal of a known portion count, then weigh what lands in the bowl.
- Divide that weight by the portion count to find your kibble's real grams per portion.
- Set each meal's portion count in the app so the day adds up to the weighed amount.
- Check again whenever you switch foods, since a new kibble size changes the math.
The app, Wi-Fi, and what happens when the power or internet drops
You set the feeding schedule in the Petlibro app: the time of each meal and its portion count, with up to 10 meals a day and reminders on the Granary 2 line. Schedules saved locally on the feeder are what keep meals coming when the connection drops.
Petlibro lists the Granary 2 on both 2.4 GHz and 5 GHz Wi-Fi, as the Chewy model's WIFI 2.4g & 5G name suggests. The OneIsAll 5G Wifi Automatic Cat Feeder, 20-cup also connects on 5G or 2.4G Wi-Fi and keeps a feeding log, per its listing; Chewy listed it at $69.99 in October 2026.
Can two people use the PetLibro app?
Yes. Petlibro lets you share one feeder with a second person by User ID, and both people must have their own Petlibro account. That suits a couple who split mealtimes, or a pet sitter who needs to see the schedule while you travel.
Can I use PETLIBRO without a subscription?
Yes. Petlibro states on its Petlibro Care page that no subscription is needed to use its smart feeders. Petlibro Care is an optional paid add-on for wellness tracking, with a Standard plan for one pet and a Plus plan for multiple pets.
Scheduled, portioned cat meals set from the PIXI app, which also adjusts portions and dispenses food.

Care pricing is hard to pin down. The Care page showed $47.99 next to a struck-through $59.99 in October 2026 without saying whether that is monthly or yearly, and the Granary 2 page shows other Care prices. On the camera feeder, cloud video needs a separate Video Cloud subscription, while microSD playback does not.
Will a PETLIBRO feeder work without Wi-Fi?
Yes, for scheduled meals. Petlibro's feeder FAQ says schedules saved locally on the feeder do not depend on the network, so a Granary 2 keeps feeding through a Wi-Fi outage. What waits for the connection is the app side: changing the schedule from your phone or checking in remotely.
Treat that as a backstop, not a guarantee. Cybernews reported an outage in which owners said their Petlibro feeders went offline, so the app should not be the only safeguard for a pet left alone. Before a trip, save the schedule on the feeder and arrange for someone to check the bowl.
Power cuts are handled differently by model:
- Granary 2: a built-in rechargeable battery gives up to 24 hours of backup power.
- Petlibro Air: its Chewy listing cites a 180-day battery life with no cables, so it does not depend on an outlet.
- Granary camera feeder: alkaline D batteries, not rechargeables, are its emergency plan. On battery power it keeps the meal schedule but turns off Wi-Fi, the camera, recording, and the reset button to save power.
- One RFID: 3 alkaline D batteries run scheduled meals during a power cut, with Wi-Fi and the reset button disabled. Petlibro says not to use rechargeable batteries.
That battery behavior explains two things owners may notice. A camera feed that goes dark during a power cut is the camera feeder saving power, and a reset will not work on these models until they are back on mains power. For the reset sequence itself, follow the manual for your model.
Jams, clogs, and kibble size: the problems owners report
Petlibro ties dispensing trouble to the food itself. Its feeder FAQ recommends dry kibble 2 to 15 mm in diameter and warns that large square or crescent-shaped pieces may jam more easily. The One RFID lists the same 2 to 15 mm range and takes dry food only.
We found no published owner-reported jam rate for Petlibro feeders, so this review does not put a number on how often they clog. When a Petlibro feeder stops dispensing, work through these checks in order:
- The kibble: measure a few pieces. Anything outside 2 to 15 mm, or large square or crescent-shaped pieces, is the first suspect.
- A stuck lid or rotor: unplug the feeder, empty the hopper, and look for a wedged piece before running a meal again.
- Light portions: if meals arrive but look small, a light kibble may weigh well under Petlibro's usual 10 g per portion, so weigh one meal.
- Power and signals: the camera feeder and One RFID drop Wi-Fi on battery power, so the app can show them offline while meals still run. If the feeder keeps beeping or shows a blinking white or flashing red light, look that signal up in your model's manual before taking anything apart.
- The wet food feeder: kibble rules do not apply to the Polar, which serves three cooled wet meals, so its manual is the guide to any alert.
Cleaning, the desiccant, and keeping food fresh
Petlibro's cleaning guidance for its pet feeders is to clean the entire feeder every 30 days, or sooner if food powder, oil, moisture, or buildup is present. On the Granary 2, Petlibro says to replace both desiccant packs every 14 days, so keep a spare desiccant bag or two on hand.
Petlibro's product pages do not say which parts are dishwasher safe, so hand-wash unless your manual says otherwise. The One RFID ships with a stainless steel bowl and holder.
A monthly cleaning, step by step:
- Unplug the feeder and take out any backup batteries.
- Empty the hopper and store the dry food in a sealed container.
- Hand-wash the bowl and wipe out the hopper, clearing food powder and oil.
- Dry every part completely, since moisture is one reason Petlibro gives for cleaning early.
- Fit fresh desiccant packs, refill the hopper, and run one meal to confirm it dispenses before your cat or dog relies on it.

Petlibro feeder alternatives: when Oneisall or Catit fits better
Owners on a tighter budget who still want Petlibro can choose the Petlibro Air Wi-Fi Automatic Dog & Cat Feeder, Black, 2-L, a 2 L model that Chewy listed at $69.99 in October 2026, with up to six meals a day and a listed 180-day battery life.
For a larger hopper at that same price, the OneIsAll 5G Wifi Automatic Cat Feeder, 20-cup was also listed at $69.99 on Chewy in October 2026. Its listing says it holds up to 10 days of food for two adult cats and offers a scheduled plan or manual feeding. Our Oneisall automatic feeder review covers it in depth.
For a cat-only home that would rather use a different app, the Catit Pixi Smart Cat Feeder serves portioned meals on a schedule through the PIXI app. Its listing adds a rubber-sealed lid, a desiccant pad, and a stainless steel dish. Chewy listed it at $111.80 in October 2026.
Neither Chewy listing states a portion size or backup power, so confirm both with the maker before you buy.
Petlibro automatic feeder questions
Frequently Asked Questions
How much food is one Petlibro portion?
On the Granary camera feeder, one portion is 20 ml, about 1/12 cup, so 12 portions make roughly one cup by volume. To turn a daily amount in cups into portions, multiply by 12: half a cup a day is 6 portions, or 3 portions at each of two meals.
Weigh that amount once, because the weight of a portion shifts with the kibble.
Does a Petlibro feeder still work if the power goes out?
Yes, within limits. The Granary 2 keeps its feeding schedule running on a built-in backup battery for up to 24 hours, and Petlibro lists a 48-hour backup on the Granary 2 Vision. The Air has no cables at all; its Chewy listing cites a 180-day battery life.
Models that take alkaline D batteries keep the meal schedule but switch off Wi-Fi, so you will not see meals in the app. For an outage longer than the backup, plan on someone checking in.
Why is my Petlibro feeder not dispensing enough food?
Two causes are documented. A portion is a fixed volume, so a light kibble delivers less weight than Petlibro's usual 10 g, and large square or crescent-shaped pieces can jam and cut a meal short.
Check that the kibble size falls within 2 to 15 mm, clear any jam with the feeder unplugged, then weigh a meal and raise the portion count if your pet needs more.
Which Petlibro feeder works for wet food?
The Polar wet-food feeder (PLAF109). It holds 3 meals of up to 6.76 oz (200 ml) each and keeps them cool with thermoelectric cooling, so there is no ice pack to swap. Petlibro says it takes canned, pouch, semi-moist, and prescription canned wet food, but advises against raw food.
Petlibro listed the Polar at $169.99 in October 2026. The Granary 2, the Granary camera feeder, and the One RFID are dry-food feeders.
Is the Petlibro camera feeder worth it?
It is worth it if seeing the bowl matters to you. The Granary camera feeder, listed at $139.99 on Petlibro's site in October 2026, adds a 1080p camera with night vision for $10 more than the Granary 2.
Two catches: cloud video in the app needs a separate Video Cloud subscription, though microSD playback does not, and the camera switches off on battery power. Our guide to the best pet feeder with camera compares other options.
