How I put this together: I haven’t used these feeders and I don’t have a cat. This comparison of the best automatic cat feeder options I have covered draws on my four earlier feeder posts, which cover roughly two hundred owner reviews Amazon surfaces on the three listings, summarised the same way as every review on this site. That is a sample, not a census: most ratings have no written review, and PETLIBRO’s sample is noticeably thinner than the other two. Star percentages are Amazon’s public figures. Nothing here is sponsored. The Amazon links on this page are affiliate links: as an Amazon Associate I earn from qualifying purchases, at no extra cost to you.
Three feeders, rated 4.4, 4.3 and 4.1 across about 27,000 ratings. If you are looking for the best automatic cat feeder of the three on reliability alone, the reviews I read will not give you one. Each listing has owners who’ve run theirs for years and owners whose unit stopped inside a few months.
What the reviews do answer is a different question, and I think it is the right one: when your feeder misses a meal, how do you find out? One of these cannot tell you. One tells you a lot, but not everything. One keeps a record that is usually right. Pick the failure you can live with and the choice mostly makes itself.

Three ways to miss a meal
Most meals from all three arrive on time for most owners. The high-star reviews are full of cats who now sit by a machine at 4am instead of on someone’s chest. The question that decides the best automatic cat feeder for you is what happens on the day one doesn’t.
VOLUAS: silence. There is no app, so a skipped meal is a skipped meal until a person notices. The owner who ran three found that one had been serving dinner and quietly skipping breakfast and lunch, and only caught it because a cat started acting restless in the evening. Another caught about five misses in four months on a home camera.
PAPIFEED: a record, which is usually right. The app logs each feed. One owner’s log said meals had dispensed on days they had not. Another got a failure alert the one time the cord came loose. My reading is that it reports what it knows went wrong, and it doesn’t always know.
PETLIBRO: the most alerts, and one gap. Low food, a jammed chute (there is an infrared sensor at the outlet), a full bowl, offline, time to swap the desiccant. What it can’t report is its own death, and owners describe units that stopped between about four and eighteen months without a warning. On August 12 this year PETLIBRO’s servers went down for part of a day, and one owner’s two-year-flawless feeder went offline with everyone else’s.
None of the three has a sensor in the bowl, as far as the listings and reviews show. “Completed” in an app means the motor was told to turn. That’s why the owners who caught problems early are, across all three listings, the ones with a cheap camera pointed at the bowl.
The best automatic cat feeder for each kind of house
No Wi-Fi, power cuts, or a barn: VOLUAS
It is the highest-rated feeder I’ve covered on this site, and the one with the fewest parts that can change under you. There’s no app to update, no account, no server. The listing’s two most-voted reviews are both about conditions an app feeder would struggle with: a power cut of about eight hours, which it rode out on batteries, and a feral cat on a porch, where the feeder sits inside an old birdcage to keep raccoons out. A barn-cat owner runs one on batteries alone and gets over a month from a set at two meals a day.
What you give up is knowing. The clock is 24-hour and has to be set before the schedule, the voice recording plays from a speaker on the underside, and three low-star owners this summer said their cats tipped it or got the lid off. Several owners in my sample have bought it again, one of them three more at once.
Away overnight and want to be told: PETLIBRO Granary
If the point of the feeder is that you will be somewhere else, Granary is built for you. Its most-voted Wi-Fi reviews praise the alerts specifically: low food, a jammed chute, a bowl too full to dispense into. One owner with two units says the jam alert came through the one time the chute clogged. An owner nearly two years in says no subscription is needed and that the brand emails everyone when there is a network problem.
Of the feeders I’ve covered it has the widest gap between best seller and best liked, though, and the 18% low ratings are about two things. The first is portions: the most-voted low review measured 20 to 50 percent of what the camera version was set to, with no pattern, and a dense-kibble owner got double. The second is lifespan, above. Budget for the desiccant pack the app asks you to replace about every two weeks. And note my sample here is about thirty reviews, thinner than the others, so hold these patterns more loosely.
Several cats, one big hopper, fine with an app: PAPIFEED
Six litres is the largest hopper here, and 70% of its ratings are five stars. Satisfied owners run two, three, even five units across a household, use Alexa alongside the app, and a few report three years or more. It is a sensible pick for a multi-cat household where someone is usually home.
Two things to know before you buy. The app has changed at least twice over the listing’s life, and one of the listing’s own images tells you to search for Smartlyn. Four repeat buyers in my sample found a new unit wouldn’t connect the way their first one did, and three of them blame the app change. When I checked the US App Store on September 22, Smartlyn had about 2.0 stars from 27 ratings.
Second, there’s no low-food alert, per a two-year owner, and the hopper is dark enough that you cannot easily see inside. Lifespans in the reviews I read split into two clumps, years or under one year, with little in between. The listing also carries Amazon’s frequently-returned notice.
What’s the same on all three
A portion is a turn of the rotor, not a weight. VOLUAS says 6 to 7 grams, PETLIBRO says 1/12 cup, PAPIFEED’s bullets give no figure. Owners who measured got numbers that matched, numbers that did not, and in PAPIFEED’s case anywhere from a sixteenth of a cup to 67 grams with a coated raw-blend kibble. The fix is the same for all three: dispense one portion by hand on day one, weigh it, and build the schedule from your number.
The first week decides it. The owners who came home to an empty bowl were the ones who left. The ones who caught a problem early were home watching, or had a camera. Run the schedule for a week while you’re around, inside the return window.
Test the backup. Pull the plug at a mealtime with batteries in. A VOLUAS owner describes it feeding through an eight-hour outage, and a barn-cat owner runs one on batteries alone. In the PETLIBRO reviews I read, one owner says the batteries didn’t take over when the unit died, another describes a button lock that blocks manual feeding in battery mode, and none describes a real outage it survived. One PAPIFEED owner found the Wi-Fi wouldn’t stay connected until batteries went in.
Your cat gets a vote
PAPIFEED has a manual-feed button on the front, and cats find it. One owner watched a cat nose it within minutes of setup; another’s log showed one cat logging eight to twelve meals a day until a washer and duct tape went over the button. VOLUAS gets tipped and its lid gets lifted, per three low-star owners. PETLIBRO is the one where nobody, in the reviews I read, described a cat getting into the hopper: it has a twist-lock lid and a touch panel that ships locked. That’s a thin sample and not a guarantee, but if your cat opens cupboards, it matters.
Best automatic cat feeder: the verdict
You are home most nights, the cat wakes you at 5am, or the feeder lives in a garage or barn: VOLUAS. Highest rating, lowest share of bad ones, nothing to update. Put a camera on it before any trip.
You travel and want your phone to tell you when something’s wrong: PETLIBRO Granary. The best alerts of the three. Test portions with your kibble in week one, and don’t treat the alerts as a promise that it’s still alive.
Two or three cats, a big hopper, and you are fine managing an app: PAPIFEED. Cover or turn the front button away from a curious cat, and if you already own one, check which app a new unit wants before you buy it.
You want the best automatic cat feeder to mean one that never misses while you’re gone for a week: none of these, and none I have read about. The honest version of that product is any of the three plus a camera on the bowl and someone who can drop by.

Questions people ask
Which is the best automatic cat feeder for travel?
PETLIBRO Granary, for its alerts, as long as you have tested portions and have a camera for the failure it can’t report. For a single night with power you trust, VOLUAS is fine too.
Do any of them need a subscription?
VOLUAS has nothing to subscribe to. PETLIBRO owners describe an optional paid tier offered at setup and no requirement. One PAPIFEED reviewer said a monthly payment was needed; nobody else in my sample said so. Check in the app.
Which one works in a power cut?
Each of the three takes backup batteries. VOLUAS is the only one where an owner in my sample describes it feeding through a real outage. Test the other two before you rely on them.
Which is best for two cats?
VOLUAS and PAPIFEED owners describe running one unit per cat. PAPIFEED’s big hopper and repeat buyers make it the common multi-cat choice here, with the app caveat above. PETLIBRO and VOLUAS both sell two-bowl models, which I haven’t covered.
Star percentages are Amazon’s public figures at the time of writing and will shift as new ratings arrive. The patterns above are my own summaries of a sample of the reviews Amazon surfaces on each listing, which is fewer than each listing’s total reviews and far fewer than its total ratings. App Store figures were checked on September 22, 2026 and will change. Product images are from the manufacturers’ listings. Specs, prices and availability change, so check the listing for current details.
