Feeding & Water
Best Automatic Cat Feeders
The American Association of Feline Practitioners (AAFP) recommends splitting a cat's daily food into several small meals spread through the day [1]. That's hard to do if you work long hours, and it's where an automatic cat feeder helps.
We picked three: a simple timed feeder with a screen and buttons, a two-bowl feeder for homes with two cats, and a Wi-Fi feeder with a camera you control from your phone. All three are for dry food.
The best automatic cat feeder for most homes is a timed portion feeder that drops small, measured meals several times a day, because that matches the AAFP's advice to split a cat's daily food into multiple small meals [1]. Gravity feeders refill the bowl as it empties, so they don't portion anything. Wet food and multi-cat homes need different designs, and no feeder replaces someone checking on your cat; both are covered below.

How we chose these feeders
We searched Amazon for automatic cat feeders and read the top organic results. We left out gravity feeders, which refill the bowl as it empties and don't portion meals.
We chose one feeder for each kind of home and checked what each listing says about portions, meals per day and power. What vets say about meal feeding comes from the AAFP consensus statement on feeding cats [1]. For water, see our cat fountain guide.
What the research says
The AAFP's 2018 consensus statement on feeding cats says a cat's daily food should be split into multiple small meals fed throughout the 24 hours, using puzzle feeders where possible [1]. It criticizes feeding large amounts once or twice a day, or leaving food out all the time, without regard to each cat's energy needs [1].
On automatic feeders it is brief: they "can also be helpful", but they don't usually give cats a chance to forage or hunt [1]. So a feeder handles the schedule. Play and puzzle feeders still matter. We found no study showing that automatic feeders prevent weight gain.
Weight is a real issue. In the Association for Pet Obesity Prevention's 2022 survey of U.S. veterinary clinics, 61% of cats were classed as overweight or obese [2]. That's an advocacy group's survey, not peer-reviewed and not a nationally representative estimate, but it's a good reason to measure portions and ask your vet how much your cat should eat.
How does an automatic cat feeder work?
There are four main designs. They solve different problems, so pick the type before the brand.
| Type | How it works | Best for | Limits |
|---|---|---|---|
| Gravity feeder | A hopper refills the bowl as the cat eats | Topping up food for a cat that self-regulates | No portion control; the AAFP criticizes leaving food out all the time without regard to energy needs [1] |
| Timed portion feeder (dry) | A motor turns a rotor at set times and drops a set number of portions | Several small meals a day; all three of our picks | Dry kibble only; size limits; can jam |
| Timed wet-food tray | Lidded compartments open one at a time on a timer, some with an ice pack underneath | One or two wet meals while you're out | Food safety limits how long food can sit (see below) |
| Microchip or RFID feeder | The lid opens only for a cat whose microchip or collar tag it reads | Homes where cats eat different diets or one steals food | Controls who eats, not how much, unless it also portions |
A feeder handles the schedule, not the hunting and foraging the AAFP says feeders usually don't provide [1]; our interactive cat toy guide covers that side. On a timed feeder, a "portion" is a unit the maker defines, not a standard. Our VOLUAS pick lists about 6 to 7 grams per portion and the oneisall about 10 grams per bowl; the Frienhund doesn't state grams. Kibble shape and density change that, so weigh one portion of your own food on a kitchen scale before you program anything.
Is there an automatic feeder for wet cat food?
Yes, but none of our three picks takes it, and the food-safety window is short. The FDA's advice for canned and pouched pet food is to refrigerate or throw out unused or leftover food promptly, and to wash bowls with soap and hot water after each use [3].
We found no pet-specific time limit for wet food in a bowl. The closest official benchmark is the USDA's rule for perishable human food: bacteria grow fastest between 40 °F and 140 °F, can double in as little as 20 minutes, and food shouldn't sit out more than 2 hours, or 1 hour above 90 °F [4]. We'd use that as a conservative guide for wet cat food too.
That shapes how to use a wet-food feeder:
- Use it for a meal due within a couple of hours of loading, not one that sits all day
- Load it straight from the fridge, and use the ice pack if it has one; we found no published test of how long ice-pack trays keep food below 40 °F
- Wash every compartment after each use [3]
- In a hot room, shorten the window to an hour [4]
VOLUAS Automatic Cat Feeder, 4L
Sold by Voluas Direct, ships from Amazon.
This is the simplest feeder here. You set one to four meals a day on its LCD screen, with 0 to 40 portion settings. The listing says a portion is about 6 to 7 grams, roughly a tablespoon, which makes small meals easy to set.
It holds 4 liters of dry food, runs on a USB power adapter, and can switch to three D-cell batteries (not included) as a backup. You can record a 10-second meal call. There's no app, which some people will prefer.
Good to know
- Small portions of about 6–7 g, per the listing
- Plug-in with battery backup
- No app or Wi-Fi needed
Keep in mind
- Dry food only
- Up to 4 meals a day, fewer than the other two
- Batteries not included
oneisall Automatic Cat Feeder for 2 Cats
Sold by oneisallstudio, ships from Amazon.
The AAFP says feeding stations should be visually separated, because making a cat eat near one it would avoid causes stress [1]. This feeder splits each meal into two stainless steel bowls on opposite sides, 16 inches apart. That spreads the cats out a little, but it is still one station.
It's set with a dial, serves up to six meals a day, and the listing says a portion is about 10 grams per bowl. It holds 5 liters, plugs in, and takes four AA batteries (not included) as a backup. The bowls are dishwasher safe.
Good to know
- Two bowls on opposite sides
- Up to 6 meals a day
- 2-year warranty listed
Keep in mind
- Both cats still eat from one unit; the AAFP suggests stations out of each other's view [1]
- Kibble must be under 0.5 inch, per the listing
- The spec says 11 pounds capacity while the title says 5 liters
Frienhund Automatic Cat Feeder with Camera
Sold by SAMHUG, ships from Amazon.
If you want to see your cat eat while you're away, this feeder has a camera with night vision and two-way audio. You set meals in the phone app, up to 15 a day, and the listing says the app shows feeding history, and the camera lets you see how much food is left in the bowl.
It has the biggest tank here, at 7 liters, with a stainless steel bowl, and works on 2.4 GHz or 5 GHz Wi-Fi. The listing says it can also run on three D-cell batteries if the power goes out.
Good to know
- Camera, night vision and two-way audio
- Up to 15 meals a day via the app
- Largest tank: 7 liters
Keep in mind
- Needs the app and Wi-Fi for the camera and remote features
- The title says 2K camera; the bullets say Full HD 3 megapixel
- The listing doesn't say whether cloud video storage costs extra
- The spec lists corded power only, while the bullets describe a 3 D-cell backup
The feeders side by side
| Product | Meals a day | Portion | Capacity | Power | Controls |
|---|---|---|---|---|---|
| VOLUAS 4L | 1–4 | About 6–7 g | 4 L | Adapter + 3 D (not incl.) | LCD buttons |

How to set up and program an automatic cat feeder
- Get a daily amount from your vet, in grams or cups. The AAFP recommends measured meals based on each cat's energy needs [1].
- Weigh one portion of your food on a kitchen scale. Run the feeder once with a single portion to check.
- Divide the daily amount into meals. The AAFP recommends multiple small meals spread through the day [1]. For example, 60 grams a day with 6-gram portions could be five meals of two portions.
- Check the kibble fits. The oneisall listing says kibble must be under 0.5 inch. Large or oddly shaped pieces are a common cause of jams.
- Fit backup batteries before you rely on it. Two of our picks don't include them.
- Run it for several days while you're home. Watch that each meal drops and that your cat eats it.
- Clean it on a schedule. The FDA says to wash pet bowls and scoops with soap and hot water after each use, and to store dry food below 80 °F [3]. Empty and wipe the hopper between bags so old crumbs and oils don't build up.
How to train a cat to use an automatic feeder
Some cats are wary of the motor noise at first. A gradual switch avoids a cat that simply stops eating:
- Put the feeder where your cat already eats, switched off, with its usual food in the bowl.
- After a few days, let it dispense one meal while you're in the room. The VOLUAS lets you record a 10-second meal call, which can help link the sound to food.
- Move more meals to the feeder over a week, keeping the total amount the same.
- Only rely on it alone once your cat is eating every scheduled meal.
Don't wait it out if your cat refuses the feeder. Cornell's Feline Health Center says hepatic lipidosis (fatty liver) is almost always accompanied or preceded by a cat not eating, is more common in obese cats, and can be fatal if not promptly reversed [5]. If your cat skips meals, go back to hand-feeding and ask your vet.
Automatic cat feeder for two cats or more
The AAFP says feeding stations should be visually separated, because making a cat eat near another it would avoid causes stress [1]. That gives you three setups:
| Setup | When it fits | Trade-off |
|---|---|---|
| One two-bowl feeder (like the oneisall) | Cats that get along and eat at a similar pace | Still one station; a fast eater can finish both bowls |
| Two single feeders in different rooms | Cats that don't get along, or eat at different times | Two to program and clean, but closest to the AAFP's advice [1] |
| Microchip feeders | Different diets, a cat on a weight plan, or a food thief | Controls who eats; check whether it also portions |
Whatever you choose, program each cat's total for the day, not a shared total, and watch the first week to see who is eating what.
Can you leave a cat alone for a weekend with an automatic feeder?
Not without someone checking in. The San Francisco SPCA advises not leaving a cat alone for more than 12 hours without someone checking on them, and says that if a sitter visits only once a day, you should add extra litter boxes so there is always a clean one [6].
A feeder handles the meal schedule between visits. It can't tell you if it jammed, lost power, or your cat stopped eating, and a cat that goes without food is at risk of hepatic lipidosis [5]. A camera feeder like our Frienhund pick lets you see the bowl, but it can't fix a problem. Before you go:
- Arrange at least daily visits [6]
- Run the feeder on its programmed schedule for a week beforehand
- Fit fresh backup batteries
- Leave plenty of water in more than one place; a cat water fountain plus a plain bowl covers a pump failure
- Add an extra litter box [6]
- Leave your vet's number and the feeder's manual with your sitter
Feeder features that matter
Small portions
The AAFP recommends several small meals a day [1]. Check the portion size in grams so you can match what your vet recommends.
Meals per day
More meal slots let you spread food out. Our picks range from 4 to 15.
Power backup
All three take batteries as a backup. The VOLUAS and oneisall don't include them, and the Frienhund listing doesn't say. Fit them before you go away.
Separate eaters
In multi-cat homes, the AAFP suggests feeding stations out of each other's view [1]. One feeder per cat does that best.
Which feeder fits your home
- Best Overall: The VOLUAS is simple and small-portioned, with no app needed.
- Best for Two Cats: The oneisall splits each meal into two bowls on opposite sides.
- Best With a Camera: The Frienhund lets you watch and schedule from your phone.
Automatic cat feeder FAQ
Are automatic cat feeders good for cats?
The AAFP says they "can also be helpful" for feeding several small meals, but they don't usually let a cat forage or hunt [1]. Add play or puzzle feeders too.
How many meals a day should a cat eat?
The AAFP recommends splitting daily food into multiple small meals across 24 hours [1]. Ask your vet how much your cat should eat in total.
Will an automatic feeder help my cat lose weight?
We found no study showing that. It can make measured portions easier. The AAFP recommends measured small meals over free-feeding large amounts [1]; ask your vet for a weight plan.
Can I use wet food in these feeders?
No. All three listings are for dry food.
What happens if the power goes out?
Each of our picks can run on batteries as a backup, per its listing. The VOLUAS and oneisall don't include them; the Frienhund listing doesn't say.
Can two cats share one automatic feeder?
The oneisall is built for two, with bowls 16 inches apart. The AAFP suggests separate feeding stations out of each other's view [1], so two feeders in different spots is better if your cats don't get along.
How long can wet cat food sit out?
We found no pet-specific limit. The FDA says to refrigerate or throw out leftover canned and pouched pet food promptly [3]. For perishable human food, the USDA says no more than 2 hours at room temperature, or 1 hour above 90 °F, because bacteria can double in as little as 20 minutes between 40 °F and 140 °F [4]. We'd use that as a cautious guide.
What happens if an automatic feeder jams while I'm away?
Should I use a gravity feeder for my cat?
Only if your vet is happy with free feeding. A gravity feeder refills as the bowl empties, so it doesn't portion meals. The AAFP's feeding statement criticizes leaving food out all the time without regard to a cat's energy needs, and recommends multiple small meals instead [1].
How do I clean an automatic cat feeder?
The FDA says to wash pet food bowls and scoops with soap and hot water after each use, and to keep dry food below 80 °F [3]. On a feeder, that means washing the bowl daily and emptying and wiping the hopper between bags. Check your manual for which parts are dishwasher safe; the oneisall lists its bowls as dishwasher safe.
