The best double automatic cat feeder for most two-cat homes is the oneisall Automatic Cat Feeder for 2 Cats, because its two bowls sit 16 in apart and its 5 L tank feeds two adult cats for about 10 days. If you want app control, the PETLIBRO 5L WiFi Feeder is the pick; for camera monitoring, choose the Frienhund with Two 1080P.

Two cats sharing one bowl is the problem this category solves. A double automatic cat feeder gives each cat its own dish and drops the same amount at each meal, so the faster eater can't clear both portions before the other arrives.

Spacing matters as much as the split, since bowls placed side by side let one cat lean across.

This guide covers nine feeders, from simple dial models to camera units. If you're still deciding whether timed feeding suits your cats, read are automatic feeders bad for cats first.

Our automatic cat feeder with timer guide covers the scheduling basics.

Best double automatic cat feeders for two-cat homes

The oneisall dial model wins for most people because it's simple and gives each cat real space at mealtime. The rest of the list covers app control, camera monitoring, no-power setups and very large kibble.

oneisall Automatic Cat Feeder for 2 Cats: Best overall

oneisall Automatic Cat Feeder for 2 Cats, double automatic cat feeders
9.7/10Our score
  • 16-inch bowl separation
  • 5 L / 20 cups capacity
  • Dial programming
  • 10 s voice recorder

A dial-programmed feeder with two opposite-facing bowls 16 in apart. Its 5 L tank covers about 10 days for two adult cats.

See it on Amazon

Pros

  • Two bowls spaced 16 in apart
  • Simple dial setup
  • Voice message plays before meals
  • Stainless bowls are dishwasher-safe

Cons

  • No app or WiFi control
  • Dry food only

This is the feeder to buy if you want set-and-forget meals without an app. A dial on the unit sets the schedule, so anyone in the house can adjust it without a phone.

The two bowls face away from each other with 16 in between, which gives each cat room to eat without crowding.

The 5 L tank holds 20 cups of dry food. oneisall says that covers about 10 days for two adult cats, enough for a weekend or a short vacation. Each portion is about 10 g, and you can set up to 6 meals a day.

A 10-second voice clip plays before each meal. The stainless bowls are food-grade, and oneisall says they're dishwasher-safe.

Multi-layer sealing and desiccants keep kibble crisp.

The trade-off is no remote control. If you travel often and want to feed from your phone, the WiFi version or PETLIBRO suits better.

ZOMISIA Automatic Cat Feeder: Best for no-electricity setup

ZOMISIA Automatic Cat Feeder, double automatic cat feeders
9.5/10Our score
  • Gravity food and water set
  • 0.8 gal capacity per tank
  • No electricity needed
  • Rotating assembly

A gravity feeder and water dispenser set that needs no power. The two parts can sit together or be split and angled.

See it on Amazon

Pros

  • Works without electricity
  • Food and water in one set
  • Splits into two pieces

Cons

  • No timed portions
  • Hand-wash only in cold water

The ZOMISIA set suits a household that wants food and water in one spot without plugging anything in. It pairs a gravity food feeder with a water dispenser, and both run on gravity alone.

Each tank holds 0.8 gal, which ZOMISIA says lasts about 7 days for small pets and 3 days for larger ones.

The parts split into two pieces or combine into one unit. A 180-degree rotating assembly lets you angle the setup to fit a corner or a wall.

That flexibility helps in a small kitchen where floor space is tight.

Cleaning is hand-wash only in cold water, so it's not dishwasher-safe. There's no timer and no portion control; the food drops as your cats eat it.

That suits free-feeding homes but not cats on a measured diet. For scheduled portions, skip this one and look at the KATALICLAB or VOLUAS.

KATALICLAB Automatic Cat Feeders for Two Cats: Best for even portion splitting

KATALICLAB Automatic Cat Feeders for Two Cats, double automatic cat feeders
9.2/10Our score
  • Meal divider for two bowls
  • 6 L storage tank
  • Up to 6 meals per day
  • 10 s meal call

A divided two-bowl feeder with a 6 L transparent tank. Its meal divider pushes the same amount into each bowl at every timed meal.

See it on Amazon

Pros

  • Meal divider for even splits
  • 6 L capacity
  • Battery backup
  • Sliding lock lid with desiccant

Cons

  • Batteries sold separately
  • No app control

KATALICLAB suits two cats that need identical portions at every meal. A meal divider splits the food so each bowl gets the same amount, which heads off the squabbling that starts when one cat gets more.

You can set up to 6 meals a day.

The 6 L transparent tank shows the food level without lifting the lid, so you know when a refill is due. A sliding lock lid and a desiccant bag keep kibble fresh and stop paws from raiding the hopper.

It runs on wall power with 3 D-size batteries as backup for outages. KATALICLAB also says the feeder can go outdoors, though keep it out of rain.

A 10-second voice recording plays at mealtime.

The limit is the lack of app control. If you want to feed from your phone, choose a WiFi model.

For plain scheduled meals, this one is a strong, steady choice.

4

Frienhund Automatic Cat Feeder with Two 1080P: Best for watching mealtime

Frienhund Automatic Cat Feeder with Two 1080P, double automatic cat feeders
9.1/10Our score
  • Two 1080P cameras
  • Night vision
  • 7 L tank
  • Slow feed option

A camera feeder with two 1080P lenses, one aimed at the bowls and one at the room. The 7 L tank and app control suit longer trips.

See it on Amazon

Pros

  • Two 1080P cameras with night vision
  • 7 L tank
  • Two-way voice
  • Slow feed option

Cons

  • Premium price tier
  • Cloud storage is a subscription

This is the feeder for owners who want to see mealtime, not just trust it. Frienhund fits two 1080P cameras, one watching the bowls and one watching the room.

Night vision keeps the picture clear after dark, and two-way voice lets you talk to your cats through the app.

The 7 L tank holds more than the 5 L models here, so it stretches further between refills. A slow feed option helps cats that gulp.

Timed plans and portions are set in the app, and you can also drop a portion manually with one tap.

Parts that touch food come off for washing, and the bowls are stainless steel. Battery backup keeps meals coming during a power cut.

The trade-off is price and storage. Cloud video needs a subscription, and the camera setup takes longer than a dial.

Buy it if peace of mind is worth the extra cost.

PETLIBRO 5L WiFi Feeder for 2 Cats: Best for app control

PETLIBRO 5L WiFi Feeder for 2 Cats, double automatic cat feeders
8.7/10Our score
  • 5G and 2.4G WiFi
  • 5 L tank
  • Up to 10 meals per day
  • Low food sensor

A WiFi feeder that splits food across two bowls and sends alerts when food runs low or the chute clogs. The app handles scheduling and feeding logs.

See it on Amazon

Pros

  • 5G and 2.4G WiFi
  • Clog and low-food alerts
  • Up to 10 meals per day
  • Airtight lock-fresh lid

Cons

  • App account required
  • No camera

PETLIBRO suits the owner who wants full control from a phone. It connects on both 5G and 2.4G WiFi, so the connection holds in more homes than a 2.4G-only feeder.

The app sets meal times, portion sizes and up to 10 meals a day.

What makes it useful for two cats is the alert system. PETLIBRO says the app notifies you when food runs low, the chute clogs or the battery drops.

Infrared sensing stops the feeder if the chute jams. Food goes evenly to two stainless bowls, and the splitter can be tuned left or right.

The 5 L tank has an airtight lid and desiccant. A 10-second voice clip plays at each meal, and multiple users can set schedules.

The trade-off is that you must register an app account to use it. If you'd rather avoid that, the dial oneisall or VOLUAS works without a phone.

6

VOLUAS Automatic Cat Feeder for Two Cats: Best for simple scheduled meals

VOLUAS Automatic Cat Feeder for Two Cats, double automatic cat feeders
8.6/10Our score
  • Dual stainless bowls
  • 6 L capacity
  • Up to 4 meals per day
  • Memory function

A no-frills double feeder that sends equal portions to two bowls on a schedule. The memory function keeps the plan after a power cut.

See it on Amazon

Pros

  • Equal portions in two bowls
  • Memory keeps schedule after outages
  • Anti-clog system
  • Locked lid

Cons

  • Caps at 4 meals per day
  • No app control

VOLUAS suits the buyer who wants a plain, reliable schedule and nothing more. Its double bowl design sends equal portions to two stainless bowls at the same time.

You set up to 4 meals a day with up to 40 servings per meal.

The 6 L tank holds enough for about 14.5 days for one cat, so two cats eat through it faster. VOLUAS states the feeder is for dry kibble only.

An anti-clog system keeps the food moving, and the top cover locks to stop sneaky snacking.

The memory function keeps your schedule after a power cut, and batteries keep it dispensing. A 10-second message recording plays at mealtime.

The limit is 4 meals a day. Cats that do better with several small meals should look at the PETLIBRO or Frienhund camera model.

For two steady meals, VOLUAS is simple and solid.

oneisall 5L WiFi Feeder for 2 Cats: Best for shared app access

oneisall 5L WiFi Feeder for 2 Cats, double automatic cat feeders
7.9/10Our score
  • 5G WiFi
  • 5 L / 20 cups
  • App sharing with family
  • 10 s voice recorder

The WiFi version of the oneisall double feeder, with app scheduling and the option to share control with family members.

See it on Amazon

Pros

  • 5G WiFi connection
  • Family app sharing
  • Even food to each bowl
  • Voice message before meals

Cons

  • Costs more than the dial model
  • No camera

This is the app-controlled version of the oneisall feeder. It connects on 5G or 2.4G WiFi and lets you set a schedule or drop a portion manually from your phone.

Feeding logs are viewable in the app.

It shares the same two-bowl layout as the dial model, with the same amount sent to each bowl. The 5 L tank covers about 10 days for two adult cats.

Each portion is about 10 g.

The app can be shared with family members, so more than one person can feed and monitor the cats. A 10-second voice clip plays before meals.

The trade-off is cost against the dial version. You pay more for remote control and app sharing.

If you travel and want to feed from your phone without a camera, this is the middle ground between the dial model and the camera feeders.

Frienhund Dual Automatic Cat Feeder with Camera: Best for cats that guard food

Frienhund Dual Automatic Cat Feeder with Camera, double automatic cat feeders
7.8/10Our score
  • 18.7-inch bowl separation
  • Two 1080P cameras
  • 7 L tank
  • Up to 20 meals per day

A camera feeder with bowls set 18.7 in apart. The wide spacing gives each cat its own space and the cameras show both bowls.

See it on Amazon

Pros

  • 18.7 in between bowls
  • Two 1080P cameras with night vision
  • Up to 20 meals per day
  • Detachable parts for cleaning

Cons

  • Needs a dual-band router for best video quality
  • Premium price tier

Frienhund's second camera feeder sets the bowls 18.7 in apart, the widest gap among the camera models here. That spacing gives each cat a personal bubble and helps when one cat guards food.

It holds 7 L and can run up to 20 meals a day with 1 to 12 portions each.

Two 1080P cameras cover both bowls. The app sends motion alerts when a cat is active, and you can save video to a micro SD card up to 128GB or to cloud storage.

Dual-band WiFi keeps the video steady.

All parts detach for cleaning, and the food hopper is BPA-free. A 5V adapter runs it daily, with 3 D-cell batteries for outages.

The trade-offs are price and setup. It costs more than the non-camera feeders and needs a dual-band router for the best video quality.

Buy it if food guarding is your main worry.

Nityers 8L Dual-Bowl Pet Feeder: Best for big kibble and long trips

Nityers 8L Dual-Bowl Pet Feeder, double automatic cat feeders
7.3/10Our score
  • 8 L / 34 cups
  • Kibble from 2 to 18 mm
  • 21-inch bowl separation
  • Up to 6 meals per day

A large-capacity feeder that takes kibble up to 18 mm and puts the bowls about 21 in apart. The 8 L tank suits long stretches between refills.

See it on Amazon

Pros

  • 8 L tank
  • Handles kibble up to 18 mm
  • Bowls about 21 in apart
  • Battery backup

Cons

  • No app or camera
  • Large footprint for small kitchens

Nityers suits homes with big kibble or long absences. The 8 L tank holds 34 cups and takes kibble from 2 to 18 mm, wider than most feeders here.

That range covers larger dental kibble and irregular shapes that jam narrower chutes.

The bowls sit about 21 in apart, the widest spacing in this group. That helps keep a piggy cat from eating from both bowls.

You can set up to 6 meals a day with 1 to 50 portions per meal.

The lid locks and a desiccant bag keeps food fresh. A silicone rotor seals the food outlet between meals.

The 6.7 in bowls are stainless steel and removable for cleaning.

It runs on an adapter with 4 AA batteries for backup. The trade-off is its size; the wide base needs more floor space.

Buy it for big kibble and long trips, not a tiny kitchen corner.

How we compared these double feeders

We compared these feeders on specs that matter for two-cat homes: how far apart the bowls sit, how much food the tank holds, how portions are split, and whether the feeder works without an app. Our score weighs specs, features and buyer feedback against what you're shopping for.

Bowl spacing got heavy weight. A double feeder only solves competition if each cat can reach its own bowl without leaning across.

Models with 16 in or more between bowls score higher than side-by-side designs.

Capacity came next. A 5 L tank covers about 10 days for two cats on most schedules; a 6 L or larger tank stretches further.

We also weighed backup power, since a feeder that stops in an outage leaves both cats hungry.

Finally, we looked at control options. Dial and button feeders suit people who want no phone involved.

WiFi and camera models earn their place for travel and monitoring. Each pick is the best fit for a named need, not a ranking of raw feature counts.

What should you check before buying a double automatic cat feeder?

Check bowl spacing, food capacity and power backup first, because those three decide whether two cats eat calmly and keep eating during an outage. Everything else is convenience.

Bowl spacing is the top filter. Aim for at least 16 in between bowls.

The oneisall gives 16 in, the Frienhund camera model gives 18.7 in and Nityers gives about 21 in. Side-by-side bowls invite one cat to guard both.

Capacity follows your travel habits. A 5 L tank covers about 10 days for two adult cats, per oneisall.

An 8 L tank like Nityers lasts longer, which matters if you're away for two weeks.

Power backup matters more with two cats, since a failed feeder means two hungry animals. KATALICLAB, VOLUAS, Nityers and the Frienhund models all take batteries.

Check which battery size each needs before you buy.

Should you pick a dial feeder or an app feeder?

Pick a dial feeder if you want simple, local control and no account. Pick an app feeder if you travel and want to feed or check in from your phone.

The oneisall dial model and VOLUAS need no phone. PETLIBRO and the WiFi oneisall run from an app.

How much food does a double feeder hold?

Most models here hold 5 L to 8 L. In cups that's about 20 to 34 cups.

For two cats eating two meals a day, a 5 L tank lasts about 10 days and an 8 L tank stretches longer.

Do you need a camera on a double feeder?

No, but a camera helps if you worry about whether food actually dropped. It also shows you how much each cat ate.

The Frienhund models have two 1080P cameras; the non-camera picks cost less and do the core job.

Which double feeder suits cats that fight over food?

The Nityers 8L and the Frienhund camera model suit food-guarding cats best, because their bowls sit 21 in and 18.7 in apart. Wide spacing beats a divider alone when one cat likes to push the other off.

A greedy cat can still follow the other to its bowl if the room is small. Place the feeder where both bowls face open space and neither cat gets cornered.

That setup does more than any feature on the box.

If your cats gulp their food, a slow feed option helps. The Frienhund with Two 1080P has one.

Otherwise, spread meals across more times per day with a feeder that allows 6 or more meals.

Is a wide bowl gap enough on its own?

Not always. Wide bowls help most when paired with even portions at each meal.

A divider like the one on KATALICLAB makes sure neither cat gets more, which reduces the reason to guard.

What if one cat eats much faster?

Set more, smaller meals so the fast eater has less time to finish and move to the other bowl. The PETLIBRO allows up to 10 meals a day.

A camera feeder also lets you watch and step in remotely.

What should you know about WiFi and camera feeders?

WiFi and camera feeders add remote control and monitoring, but they depend on a stable network and, for cameras, sometimes a subscription. Buy one only if those extras earn their keep.

A 5G-capable feeder like the PETLIBRO or the WiFi oneisall connects more reliably in homes with a 5G router. Camera models like the Frienhund pair need dual-band WiFi for steady video.

Check your router before you buy.

Cloud video storage on the Frienhund models needs a subscription. Local storage on a micro SD card avoids that cost.

For app feeders without a camera, the trade-off is simpler: you get remote feeding and logs, but no view of the bowls.

If your feeder ever stops dropping food, our guide to why my automatic cat feeder is jammed covers the usual fixes. Chute clogs and food that's too large are the common culprits.

Do camera feeders work without WiFi?

No. The app needs a network to show video and send alerts.

Without WiFi you lose remote viewing. The feeder may still dispense on its schedule if it has battery backup and the schedule is stored on the unit.

Is a 5G feeder better than 2.4G?

A 5G connection is often more stable and handles video better. But not every home has a 5G router.

A dual-band feeder like the PETLIBRO works on either, which makes it the safer buy.

How do you set portions for two cats?

Set the portion size per bowl, not per feeder, and pick an even split so each cat gets the same amount. Most models here let you choose meals per day and portions per meal.

The oneisall dial model uses portions of about 10 g, and the portion means the amount in each bowl. That's a fair split by design.

KATALICLAB's divider does the same job by pushing equal food into each bowl.

Start with the amount your vet recommends for each cat's weight, then split it across meals. If one cat needs more food than the other, a double feeder with a single shared portion size won't fix that.

You'd feed the cats separately or use two single feeders.

Check the kibble size against the feeder's limit. The oneisall takes kibble under 0.5 in.

Nityers takes 2 to 18 mm. Food that's too large is the most common reason a feeder jams.

Can you set different portions for each cat?

Not on most double feeders, which send the same amount to both bowls. If your cats need different amounts, feed them separately or use one single feeder each.

A divider feeder like KATALICLAB is best when both cats eat the same portion.

What kibble size works in these feeders?

Check each model's limit. The oneisall takes kibble under 0.5 in.

Nityers handles 2 to 18 mm. Stay within the stated range and keep the chute clean to avoid jams.

Which double feeder is best for long trips?

The Nityers 8L and the Frienhund camera feeders suit long trips best, because their tanks hold 7 L to 8 L and both offer battery backup. Larger tanks mean fewer refills while you're away.

Nityers says its 8 L tank feeds two cats for up to 2 weeks. That's the longest stretch in this group.

The Frienhund camera models hold 7 L and let you watch mealtime from anywhere.

For a weekend, a 5 L tank like the oneisall's covers it. For two weeks, go bigger.

Pair a large tank with battery backup and a locked lid so a power cut or a curious paw doesn't end the schedule early.

How long can a feeder go between refills?

It depends on tank size and portions. A 5 L tank covers about 10 days for two cats.

An 8 L tank can reach about 2 weeks. Check the tank window every few days and refill before it's empty.

What if the power goes out while you're away?

Battery backup keeps the feeder running. KATALICLAB, VOLUAS, Nityers and the Frienhund models take batteries.

Install fresh batteries before a long trip and keep a spare set on hand.

Verdict: which double automatic cat feeder should you buy?

Buy the oneisall Automatic Cat Feeder for 2 Cats for most two-cat homes. Its 16 in bowl gap, 5 L tank and dial setup cover scheduled meals without an app or a subscription.

For app control, choose the PETLIBRO 5L WiFi Feeder; for camera monitoring, the Frienhund with Two 1080P; for big kibble and long trips, the Nityers 8L.

If you want the simplest possible setup, the ZOMISIA gravity set needs no power at all. The VOLUAS is the pick for plain scheduled meals with a memory function.

The KATALICLAB is best when even portion splitting matters most.

For a broader look at two-cat feeders, our guide to the best automatic cat feeder for 2 cats covers more options and setups. Whichever double automatic cat feeder you pick, check bowl spacing and backup power first; those two decide whether both cats eat calmly every day.

Frequently asked questions

Do double feeders really stop cats from stealing each other's food?

They help when the bowls sit far enough apart. Spacing of 16 to 21 in between bowls keeps cats from reaching into the other bowl, as on the oneisall and Nityers models.

A greedy cat can still push in if bowls sit close together.

Can I use wet food in a double automatic cat feeder?

No. These feeders move dry kibble through a chute, so wet food clogs the mechanism.

Voluas states its feeder is for dry kibble only.

Serve wet food separately and use the feeder for the dry part of the diet.

How long does a 5 L tank last for two cats?

oneisall says a full 5 L tank feeds two adult cats for about 10 days. Actual time depends on portion size and how many meals you set.

Check the tank window every few days and refill before it runs low.

What happens to a double feeder during a power cut?

Models with battery backup keep dispensing on schedule. KATALICLAB, VOLUAS, Nityers and Frienhund all take batteries for backup.

The oneisall dial model and ZOMISIA gravity set handle outages differently, so plan for the one you buy.
