9 Best Outdoor Automatic Cat Feeder (November 2026)
The best outdoor automatic cat feeders include the Amazon Basics Automatic Pet Water Dispenser for covered porches, the oneisall Automatic Cat Feeder for 2 Cats (best overall for two outdoor cats), and the ANDOLL HOME Automatic Cat Feeder for garages and carports.
On this page (5 sections)
The best outdoor automatic cat feeder for most homes is the oneisall Automatic Cat Feeder for 2 Cats, because its sealed 5 L hopper and two spaced bowls feed a pair of cats on a schedule. For a covered porch, the Amazon Basics gravity set keeps food and water topped up with no electricity at all.
Outdoor feeding means choosing around weather first and features second. A feeder that sits under a roof stays dry and keeps kibble crisp, while one in the open risks soggy food and a wet power cord.
Start with our guide to the best automatic cat feeder for 2 cats if you feed more than one. Our explainer on whether automatic feeders are bad for cats covers the health questions to settle before you buy.

The best outdoor automatic cat feeders for porches, garages and carports
The best pick overall is the oneisall feeder, since it feeds two cats on a schedule from a sealed tank. Every other feeder here wins for a named outdoor setup, from a rain-sheltered porch to a garage with unreliable power.
Amazon Basics Automatic Pet Water Dispenser: Best for covered porches
- 152 fl oz food hopper
- 135.3 fl oz water bottle
- Gravity feed, no power needed
- Anti-skid rubber feet
A gravity food and water set that keeps refilling bowls without electricity. Best under a roof where rain can't reach the hoppers.
Pros
- No power or batteries needed
- Side cut-out handles make lifting easy
- Wide opening for simple refills
Cons
- Hand wash only
- Gravity feed needs level ground
The Amazon Basics set suits a covered porch where you want food and water handled in one simple unit. Its 152 fl oz food hopper and 135.3 fl oz water bottle use gravity to keep both bowls filled, so there's no cord, no timer and nothing to program.
Anti-skid rubber feet hold the base steady on a wooden deck or concrete step, and side cut-out handles make it easy to lift for cleaning. The extra-wide opening means you can top up without a funnel.
The base measures about 14 by 8 inches and stands roughly 16 inches tall, so it tucks against a porch wall without taking much floor.
Hand washing is the trade-off: the base and hoppers can't go in the dishwasher. Against the timer feeders here, this set gives up scheduling, so it suits free-feeding rather than measured meals.
Choose it for simple, power-free feeding under cover.
oneisall Automatic Cat Feeder for 2 Cats: Best overall for two outdoor cats
- 5 L hopper holds 20 cups
- Two bowls set 16 in apart
- 6 meals a day in 10 g portions
- 10 s voice recorder
A timed feeder built for two cats, with bowls far enough apart that each cat eats in its own space. The sealed hopper suits a sheltered outdoor corner.
Pros
- Stainless steel bowls are dishwasher safe
- Voice call plays before each meal
- Sealing plus desiccant keeps kibble crisp
Cons
- Needs a power outlet
- Kibble must be under 0.5 in
The oneisall feeder is the best overall pick because it's built for two cats from the start. Its 5 L hopper holds 20 cups, enough for two adult cats for about 10 days, and the bowls sit 16 in apart so each cat eats without crowding.
Meals run up to six times a day in portions of about 10 g, which is roughly 1/12 cup. The sealed hopper with desiccants keeps kibble crisp in humid outdoor air.
A 10 second voice recording plays before each meal to call the cats in.
The stainless steel bowls are dishwasher safe, which matters when they sit outside. The catch is power: it needs an outlet, so place it where a cord can reach safely under cover.
Kibble also has to be under 0.5 in. That makes it the pick for scheduled meals on a sheltered patio.
ANDOLL HOME Automatic Cat Feeder: Best for garages and carports
- 4 L hopper
- Battery backup with 3 AA cells
- Anti-jam swinging food device
- 8 degree tilted bowl
A timer feeder with battery backup so a power cut doesn't stop meals. The anti-jam device and tilted bowl suit a garage or carport setup.
Pros
- Batteries keep it feeding during outages
- Anti-jam swing device
- Desiccant box keeps food dry
Cons
- Batteries not included
- Single bowl only
ANDOLL HOME solves the outdoor power problem with a dual supply. It runs from a 5V DC adapter day to day, and three AA batteries keep meals going during a power cut, so a storm doesn't leave cats waiting.
The 4 L hopper includes a desiccant box to keep food dry, and a swinging device inside the dispenser keeps kibble moving so it doesn't jam. The bowl tilts 8 degrees, which is a comfortable angle for a cat eating on a raised surface.
A voice recording of up to 10 seconds plays three times at each set meal to call your cat.
A finger-operated lid keeps paws out of the tank, handy when the feeder sits somewhere reachable. Compared with the oneisall, it feeds one bowl instead of two.
Pick it for a garage or carport where outages happen and a single cat eats.
HWONMTE Automatic Cat Feeder and Water Dispenser: Best for week-long trips
- About 6 lb food capacity
- 1 gallon water bottle
- Stainless steel food bowl
- Gravity feed with leak guard
A large gravity combo that can cover small and medium pets for about a week. The stainless steel bowl and leak-guard valve suit a sheltered outdoor spot.
Pros
- Large food and water capacity
- Stainless steel food bowl lifts out
- Spiral valve design limits leaks
Cons
- Hand wash recommended
- Gravity feed needs a level surface
HWONMTE suits owners heading away for a week. The gravity set holds about 6 lb of food and 1 gallon of water, which the brand says covers small and medium pets for about 7 to 9 days.
Large pets get closer to 3 to 5 days from the same fill.
The food bowl is stainless steel and lifts out for cleaning, so the base stays put while you wash up. A spiral and spring valve design keeps the water bottle from leaking onto the ground, and the clear hoppers show when a refill is due.
The food outlet takes large, medium and small kibble, though the brand advises a gentle shake after filling to settle the food.
Like all gravity feeders, it needs level ground so food flows evenly. It's also hand wash recommended.
Compared with the Amazon Basics set, it holds more and adds a stainless bowl. Choose it for longer trips with one or two cats under a roof.
ZOMISIA Automatic Cat Feeder: Best for tight outdoor corners
- 0.8 gal food and water
- 180 degree rotating assembly
- Splits into two parts
- No electricity needed
A gravity set that breaks into two pieces or combines at several angles. The flexible layout fits narrow porch and balcony corners.
Pros
- Splits or combines at multiple angles
- No power needed
- Easy to take apart for cleaning
Cons
- Hand wash in cold water only
- Not dishwasher safe
ZOMISIA fits odd outdoor spaces. The set splits into two separate pieces or combines into one, and the 180 degree rotating assembly lets you change the angle to suit a narrow balcony corner or the side of a porch step.
Each part holds 0.8 gallons, enough for small pets for about 7 days and big pets for around 3. The tanks and bases separate for cleaning in cold water.
A filter plate sits in the water side, and the brand notes the outlet hole should face inward when you fit it; if the plate floats up, the waterer still works without it.
That cold-water hand wash is the trade-off, since the parts aren't dishwasher safe. Compared with the HWONMTE set, it's more adaptable in layout but holds less.
Pick it when space is tight and the feeder has to fit around furniture or a railing.
PETLIBRO Granary 5L WiFi Automatic Feeder: Best for app control outdoors
- 5 L hopper
- 5 GHz and 2.4 GHz WiFi
- Up to 10 meals a day
- Low-food and jam alerts
A WiFi feeder you can program and monitor from the app. Best where the feeder sits under cover but you still want remote control of meals.
Pros
- App scheduling from anywhere
- Alerts for empty tank and jams
- Twist-lock lid and rotor deter raids
Cons
- Needs WiFi in range
- Single bowl only
PETLIBRO Granary is for the owner who wants app control while the feeder sits outside under cover. Its 5 L hopper runs up to 10 meals a day, and the app lets you set portions and check feeding records from anywhere on 2.4 GHz or 5 GHz WiFi.
Portions run from 1 to 48 per meal, each about 1/12 cup.
Alerts cover an empty tank, a jam, a low battery or a blocked outlet, and an infrared sensor stops dispensing when the food outlet is blocked. A twist-lock lid and rotor in the tank base make it harder for a cat to raid the food, and a desiccant bag with a sealing strip keeps kibble crisp.
You can record up to 10 voice messages of 10 seconds each and adjust the volume.
The trade-off is that it needs WiFi in range and feeds a single bowl. Compared with the oneisall, it gives up the second bowl for remote scheduling.
Choose it for a covered patio where you want to adjust meals from your phone.
Wefeedy Automatic Cat Feeder and Water Dispenser: Best for simple gravity setup
- 3.3 L food and water
- BPA-free PP and PET
- Siphon water design
- No electricity needed
A basic gravity pair with matched 3.3 L tanks. Best for one cat or a small pair under a roof, with simple filling from the top.
Pros
- Matched food and water tanks
- Siphon keeps the water level steady
- Clear bottles show fill level
Cons
- Smaller capacity than the big gravity sets
- Needs hand washing
Wefeedy keeps the outdoor setup simple. Food and water tanks both hold 3.3 L in BPA-free PP and PET, and gravity moves food and water down as bowls empty.
The siphon design holds the water at a steady level without spilling onto the ground.
The brand says 3.3 L covers a small pet for about 6 days and a large pet for about 2. You fill food from the top, and clear bottles show how much is left.
Installation is just assembly plus a regular refill, so there's no timer to learn. A wide base gives the cat room to eat and drink without nudging the unit.
The smaller tanks are the trade-off against the HWONMTE set. Pick it for one cat or a small pair under cover, and for owners who want the least setup possible.
PETLIBRO RFID Automatic Cat Feeder: Best for stopping food raids
- RFID collar tag opens the lid
- 3 L hopper
- App diet tracking
- Battery backup
A feeder that opens only for the cat wearing its RFID tag. Best where a neighbor cat or a greedy housemate keeps stealing outdoor food.
Pros
- Only the tagged cat gets the food
- Tracks how much each cat eats
- Battery backup for outages
Cons
- Works only with the supplied collar tag
- Smaller 3 L hopper
PETLIBRO RFID earns its place when visiting cats keep eating your cat's food. The lid opens only when the cat wearing the supplied RFID collar tag approaches, so neighbor cats and greedy housemates can't get at the bowl.
It's aimed at multi-cat homes, special diets and weight plans.
The 3 L hopper holds about two weeks of food for one cat, and the app tracks how much each cat eats. Dual-band WiFi keeps remote scheduling stable, and a backup battery keeps feeding through outages.
Low-food alerts land on your phone when the tank runs down.
Only the provided tag works, so you can't swap in another collar's chip. Compared with the Granary, it adds access control but holds less food.
Choose it for multi-cat porches or when your cat is on a special diet.
Frienhund 7L Feeder With 2K Camera: Best for watching outdoor cats
- 7 L hopper holds 29 cups
- 2K camera with night vision
- Dual-band WiFi
- Two-way audio
A large-capacity feeder with a camera so you can see and talk to your cat. Best for a covered patio where you want eyes on the bowl.
Pros
- Camera with night vision
- Very large 7 L hopper
- Two-way audio lets you talk to your cat
Cons
- Priciest pick here
- Needs dual-band WiFi in range
Frienhund packs a camera into a feeder. The 2K camera with night vision and two-way audio let you see and talk to your cat from the app, and the 7 L hopper holds 29 cups for long stretches away.
The camera records to a TF card up to 128GB or to cloud storage, and motion detection sends an alert when your cat moves.
Meals can be scheduled up to 15 times a day in up to 20 portions each, and dual-band WiFi keeps video steady. The tank and stainless steel bowl detach for cleaning, and a carabiner lets you anchor the feeder to a wall so it isn't knocked over.
The food tank is BPA-free.
The high cost and WiFi dependence are the trade-offs against the simpler feeders here. Pick it for a covered patio where you want to watch the bowl as well as fill it.
How these outdoor cat feeders compare
The main split is between gravity sets that need no power and timer or WiFi feeders that schedule meals. Capacity, bowl count and weather cover decide the rest.

How we compared these feeders
We checked each feeder's capacity, power supply, bowl count and sealing features against the demands of outdoor feeding. Our score weighs specs, features and how well each model fits a covered porch, garage or carport.
A feeder left in the open gets rained on and its kibble goes soft, so we ranked models with sealing lids and desiccant boxes higher for outdoor use. Battery backup counted heavily too, since an outdoor outlet can lose power in a storm.
We noted which feeders alert you when the tank runs low, since an empty hopper outdoors is easy to miss.
We also looked at cleaning. Stainless bowls that go in the dishwasher scored better for outdoor feeding than hand-wash-only tanks.
Capacity was judged by how many days the tank covers one or two cats.
Finally, we weighed bowl count and spacing, because two outdoor cats need room to eat apart. Our comparison of feeders for 2 cats covers that point in more depth.
Which outdoor feeder suits your setup?
Is a gravity or a timer feeder better outside?
A gravity feeder is better for a covered porch where you free-feed and want no cords. A timer or WiFi feeder is better when you need set portions and battery or app backup.
Gravity sets like the Amazon Basics, HWONMTE, ZOMISIA and Wefeedy keep bowls filled without power. Timer feeders like the oneisall and ANDOLL HOME let you control portions and meal times.
Pick gravity if the spot stays dry and your cat eats sensibly. Pick a timer if your cat overeats from a full bowl or you want meals split through the day.
How do you keep outdoor feeder food dry?
Keep the feeder under a roof and choose a hopper with a sealing lid and a desiccant compartment. ANDOLL HOME includes a desiccant box, and the oneisall feeder uses multi-layer sealing plus desiccants.
The PETLIBRO Granary adds a sealing strip to its twist-lock lid.
Rain is only part of the problem. Humid air softens kibble even in a sheltered spot, so swap desiccant packs as the maker advises and check that food still feels crisp at each refill.
If the feeder must sit fully in the open, no model here is built for that. Move it under an overhang, into a garage, or onto a covered balcony instead.
What should you check before putting a powered feeder outdoors?
Check that an outdoor-rated outlet or a safe covered route reaches the feeder, and that the model has battery backup. A wet cord is the real risk, so the plug should stay dry at all times.
ANDOLL HOME runs on batteries during outages, and the Frienhund uses 3 D cells as backup. The PETLIBRO Granary and RFID feeders also alert you to a low battery in the app.
A WiFi feeder also needs a signal at the feeder's spot, so test the connection before you commit to that corner of the porch.
If the only spot is far from power and shelter, a gravity set is the safer choice. It needs no cord, so there's nothing to get wet or trip over.
How much food should an outdoor feeder hold?
A 3 to 5 L hopper suits most single cats for several days. Pick 5 L or more when you travel often or feed two cats, since a bigger tank means fewer refills and less chance of running empty.
The oneisall 5 L tank covers two cats for about 10 days. The HWONMTE set holds about 6 lb of food and a gallon of water for roughly a week.
The Frienhund 7 L tank runs longer still.
Bigger isn't always better outdoors. Food sits in the tank for days, so a smaller tank that you refill more often keeps kibble fresher in warm or humid weather.
Can you stop other cats eating from an outdoor feeder?
Only an RFID feeder can tell cats apart. The PETLIBRO RFID opens its lid for the cat wearing the supplied collar tag and keeps other cats out.
Timer and gravity feeders can't do this. If visiting cats are the problem, either use the RFID model or move the feeder somewhere only your cat can reach.
The RFID feeder's 3 L tank covers one cat for about two weeks. That's a smaller hopper than the oneisall's 5 L, so weigh access control against refill frequency.
For a single outdoor cat with no raiders, the simpler feeders here cost less and do the job.
What if the feeder jams or the food stops flowing?
Most jams come from kibble that's too large for the outlet or from food bridging in the tank. Check the maximum kibble size and give the tank a gentle shake after filling to settle the food.
The oneisall feeder takes kibble under 0.5 in.
ANDOLL HOME builds in a swinging device to keep food moving. The PETLIBRO Granary alerts you in the app when food jams.
Gravity sets clear when the bowl empties and food settles down.
If meals stop, our guide to why your automatic cat feeder is jammed walks through the usual fixes. For scheduled meals in any weather, a feeder with a timer gives you the most control.
Verdict
The oneisall Automatic Cat Feeder for 2 Cats is the best outdoor automatic cat feeder overall, with a sealed 5 L tank and two spaced bowls for scheduled meals. Choose the Amazon Basics set for a power-free porch, or ANDOLL HOME when a garage outlet can fail.
For longer trips away, the HWONMTE gravity set holds a week of food and water. The PETLIBRO RFID is the pick when other cats raid the bowl.
Whichever you choose, keep it under cover and check the food stays dry and crisp.

Frequently asked questions
Can an automatic cat feeder sit outside in the rain?
No, most automatic feeders are not built to sit in direct rain. Place them under a roof, porch overhang or in a garage so the hopper and power cord stay dry.
Do outdoor automatic cat feeders need electricity?
Gravity models need no power at all, since food and water flow down as bowls empty. Timer models need an outlet, and it's worth picking one with battery backup so meals continue during a power cut.
How much food do outdoor cats need in a feeder?
That depends on your cat and your vet's advice, not on the feeder. Use the feeder to split the daily amount into set meals rather than topping up a full hopper whenever it dips.
Will rain or damp spoil the food in an outdoor feeder?
Damp air can soften kibble even under cover. Choose a hopper with a sealing lid and a desiccant compartment, and check that the food still feels crisp when you refill.
What size feeder suits a cat fed on a porch?
A 3 to 5 L hopper covers several days for one cat. Pick a larger tank only when you travel often or feed more than one cat, since food sits longer and freshness matters more.
