Most automatic pet feeders bought online get used for about a fortnight before they end up at the back of a cupboard. Either the kibble jams in the chute, or the app is so unreliable that the owner stops trusting it, or the cat works out how to lever the lid open by Tuesday. The market is not short of feeders. It is short of feeders that you can confidently leave to do their job for a long weekend without coming home to a hungry pet.
This guide is built around that test: which automatic pet feeders, available on Amazon.co.uk, are reliable enough that you would actually trust them while you were away from home? We have grouped recommendations by household type rather than by ranking, because the right feeder for a single cat in a flat is rarely the right feeder for two dogs in a family home.
What actually matters in an automatic pet feeder
A surprising amount of marketing copy focuses on features that sound clever and matter very little day-to-day. App control over Wi-Fi is genuinely useful. A camera built into the feeder almost never is — if you want to see your pet, buy a separate pet camera. Voice recording for “dinner time, Bella” is charming for a week and ignored thereafter.
What matters, in roughly this order:
Reliability of the dispensing mechanism. Dry kibble of varying sizes needs to drop cleanly through the chute every time. Cheaper feeders use a basic auger that jams on irregular kibble shapes. Better feeders use a screw-and-rotation system with anti-jam reverse functionality. If you are feeding a brand with chunky or oddly shaped kibble, this is the single most important specification.
Hopper capacity matched to your absence pattern. A 1.5-litre hopper is plenty for a single cat over a weekend. A 6-litre hopper is what you need for two larger dogs across a working week. Oversizing the hopper has a hidden cost: kibble at the bottom of a half-empty 6-litre hopper sits exposed to air for weeks, going stale. Match the hopper to your real usage, not to the absolute longest trip you might take.
Power resilience. A mains-powered feeder is fine until your home loses power for two hours and the schedule resets. The better feeders run on mains with battery backup (typically 3-4 D-cell batteries), so a brief outage doesn’t strand your pet. If you cannot guarantee uninterrupted mains power, the battery backup is non-negotiable.
Portion control that actually corresponds to grams. Cheap feeders dispense “one portion” with the volume defined by the manufacturer’s plastic cup. Better feeders let you set portions in grams or in calibrated 5g increments. If your vet has put your pet on a controlled diet, you need the latter.
App quality and account stability. This is where the cheap end of the market falls apart. The hardware can be fine but the app crashes, the schedule fails to sync, the Wi-Fi drops the device, the manufacturer’s cloud service goes down for a weekend. PETKIT and SureFeed have mature apps. Many of the lower-priced brands do not.
The shortlist
| Feeder | Best for | Hopper | Power | Wet food? | App | Price band |
|---|---|---|---|---|---|---|
| PETKIT Fresh Element Solo | Single cat or small dog, app-controlled | ~3L | Mains + 3xD backup | No | Mature | Mid-range |
| Petlibro Granary Wi-Fi | Mid-range workhorse, multiple pets | 4L or 6L | Mains + 3xD backup | No | Mature | Mid-range |
| SureFeed Microchip Pet Feeder | Multi-pet households (food protection) | Single bowl | 4xC batteries | Yes | None | Mid-range |
| Honeyguaridan A36 | Wet food and fresh food | 6 sealed compartments | 3xD batteries | Yes | None | Budget |
| Faroro Automatic Pet Feeder | Budget-conscious, single dry-food pet | ~6L | Mains + 3xD backup | No | Basic | Budget |
Best overall for a single cat: PETKIT Fresh Element Solo
If you have one cat in a flat or small house and you want a feeder that you can trust over a long weekend, the PETKIT Fresh Element Solo is the obvious starting point. The hopper is sealed against air and pests, the auger handles standard cat-kibble sizes without jamming, and the app — which is the make-or-break part of any smart feeder — is genuinely mature. Portions are calibrated in 5g increments, which matters more than people realise once a vet has prescribed a calorie target.
The trade-off is the hopper size. Three litres is fine for a week of single-cat feeding, but it is too small for a household with two cats, and it is much too small for a dog of any size. Buying it for a multi-pet home would be a mistake; buying it for one cat is the closest thing to a default recommendation in this category.

Best for dogs and multi-pet households: Petlibro Granary Wi-Fi
The Petlibro Granary in its 6-litre Wi-Fi configuration is the workhorse of this category. The dispensing mechanism is more forgiving of varied kibble shapes than the cheaper end of the market, the hopper is large enough to feed two medium dogs across a week, and the app — while less polished than PETKIT’s — is reliable enough day-to-day. Voice recording is included, but treat that as a free extra rather than a reason to buy.
The Granary’s main weakness is footprint. It is a tall, broad unit, and a small kitchen will feel its presence. If counter space is tight, look at the smaller 4-litre version, which uses the same internals.

Best for multi-pet households where one pet steals: SureFeed Microchip Pet Feeder
This is a different category of product, and worth understanding properly. The SureFeed is not a hopper-and-schedule feeder. It is a microchip-activated bowl that opens only for the registered pet. If you have one cat on a prescription diet and another cat that hoovers up everything in sight, this is the only practical answer short of feeding them in separate rooms.
It works with both wet and dry food, which is rare in this category. It runs on C-cell batteries rather than mains, which means no cable trailing across the kitchen but does mean keeping an eye on battery levels. Pair it with a separate scheduled feeder if you also need timed dispensing — the SureFeed handles the access-control problem; it does not handle scheduling.

Best for wet food and fresh food: Honeyguaridan A36
Most automatic feeders are dry-food only, for the obvious reason that wet food spoils within hours at room temperature. The Honeyguaridan A36 solves this with six sealed compartments and integrated ice packs in the lid. Each compartment holds a single meal, which means it is fundamentally a six-meal device rather than a continuous-feeding one. For a long weekend with a cat that needs morning and evening wet food, that maths works. For a full working week, it does not.
Treat this as a niche tool. If your pet eats only dry food, do not pay the premium for compartments you will never use.

Best budget option: Faroro Automatic Pet Feeder
The Faroro is the feeder we would recommend if you want app control and a sensible hopper size, and you are not prepared to pay mid-range prices to get them. The build quality is plainly less robust than PETKIT or Petlibro — the lid clicks rather than seals, and the app is functional rather than pleasant — but the dispensing mechanism is reliable for standard kibble shapes, and the price-to-capacity ratio is genuinely competitive.
What we would not do is rely on the Faroro for a long absence. For day-to-day topping up while you are at work, it is fine. For a fortnight in the Mediterranean, buy the Petlibro instead.

What to avoid
Three categories of automatic feeder are routinely overrepresented in roundups and routinely disappointing in practice. Worth being explicit about them.
The first is the cheapest tier of unbranded Amazon feeders that show up in search results at premium-volume listings. The hardware is often fine; the app and the manufacturer’s cloud service rarely are. When the cloud service is hosted in a region with patchy uptime, your feeder becomes unreliable in ways you cannot diagnose. The branded mid-range is worth the extra spend.
The second is feeders with built-in cameras. The cameras are typically poor quality — low resolution, narrow field of view, fixed at a downward angle that captures the bowl and very little else — and they push the price into a tier where a separate, properly designed pet camera makes more sense. If you want to watch your pet eat, buy the feeder and the camera separately. We cover that decision in our pet camera buying guide.
The third is feeders without battery backup. A schedule that resets every time your power blips for ten seconds is not a schedule you can rely on.
Pre-purchase checklist
Before you buy, confirm:
- The hopper capacity matches your real absence pattern, not your worst-case absence
- The feeder has battery backup if you cannot guarantee uninterrupted mains power
- Portions are adjustable in gram-equivalent increments small enough for your pet’s diet
- The app and cloud service are from a brand with at least two years of UK presence
- Your pet’s kibble is a shape and size the auger handles (check user feedback for your specific food brand)
- If you have multiple pets, you have a plan for which pet eats from which device
- You have a backup plan for power cuts longer than the battery backup duration
- For wet food: you have realistic expectations about meal count, not continuous feeding
Frequently asked questions
Will an automatic feeder work for a pet on a weight-loss diet?
Yes, provided the feeder supports portions in grams or in calibrated small increments. The PETKIT and Petlibro both do this; cheaper feeders with “1 portion = whatever the cup holds” controls do not. Your vet will give you a daily gram target; divide it across the meals the feeder is set for, and the feeder handles the rest. The advantage of a feeder over manual feeding for weight loss is that nobody can be guilt-tripped into a top-up.
Can my pet break into the feeder?
Cats are inventive. Most feeders use a downward-pivot lid that resists pawing, but a determined cat can defeat a poorly-designed lid within a week. The PETKIT and Petlibro hoppers are sealed with a clip-down lid that has so far resisted serious feline engineering attempts. Anecdotal user feedback is the best guide here.
What about Wi-Fi connectivity if my router is unreliable?
All the recommended feeders fall back to the last programmed schedule when Wi-Fi drops. You lose remote control and notifications, but the feeder continues to dispense on its programmed schedule. This is the correct design — a feeder that depended on live cloud connectivity to dispense food would be unsafe — but it is worth confirming for any specific model before buying.
Should I get a feeder with a camera, or buy them separately?
Buy them separately. Built-in feeder cameras are almost always compromised on optics, field of view, or both. A dedicated pet camera, mounted at the right height for the room, is more useful and usually cheaper than the cost premium of a feeder-with-camera over a feeder-without.
How long do automatic feeders typically last?
Mid-range branded feeders should comfortably manage three years of daily use. The failure mode is rarely the dispensing mechanism — it is the cloud service being discontinued by the manufacturer, which retires app control and turns the feeder into a basic timer. Buying from a brand with a track record reduces this risk; buying from a brand whose first product launched last year increases it.
