Best Cat Food and Water Dispenser: Three Listings Compared

As an Amazon Associate we earn from qualifying purchases. Details

The best cat food and water dispenser is the one whose listing states the food capacity, the water capacity and the power source, because not every listing gives all three. This roundup compares three dispensers from the first six Amazon.com results for the keyword, read on 22 October 2026. Three of the six were left out, because they held food only or were listed for dogs. The three that remain give food capacities of 5 L, 5 L and 1.3 kg, and water capacities of 5 L, 3.5 L and 0.8 gallons, so the figures need a careful comparison.

Quick answer

• For timed meals, two listings name a timer with a set number of meals. The Yuposl and oneisall listings each give up to 6 meals a day. The Gardner listing describes a gravity set and does not give a meal count.
• For power, the Gardner listing needs no power cord or battery. The Yuposl listing needs a plug plus 3 D-cell batteries for backup, and the oneisall listing needs a Type-C cord plus 4 AA batteries for backup.
• For the largest water tank, the Yuposl listing gives 5 L of water, against 3.5 L on the oneisall listing and 0.8 gallons on the Gardner listing.
• For WiFi control, the Yuposl listing says it does not support WiFi. The oneisall page shows a WiFi option as a separate variant, and its standard option does not name WiFi. The Gardner listing names no WiFi at all.

Food and water in one unit, or two

A cat food and water dispenser can be one unit with a timer, or a pair of gravity bowls with no timer. The three listings here use different designs, and the design decides how the food and water are supplied. Yuposl and oneisall are timed feeders, so food drops into a bowl when the schedule says so. Gardner is a gravity set, so the food and water replenish as the cat eats or drinks from the base.

The Yuposl listing describes “a single unified body” with a 21-cup or 5 L food hopper beside a 1.32-gallon or 5 L water tank. Its bullets say the two parts keep kibble and water apart, with a dedicated desiccant compartment on top of the food hopper. The oneisall listing describes a dual-compartment design that keeps food and water separate, and a stable triangular base. The Gardner listing describes a 2-in-1 gravity feeder and water dispenser, and says the food and water parts replenish on their own once the pet finishes what is in the base.

For a household that is out for a long day, a timed feeder gives set meals, while a gravity set gives food on demand. For a household where the cat eats little and often, a gravity set may suit the routine better. A slow-eating bowl guide covers a different way to slow meals if the cat eats too quickly. The listings do not compare these two approaches with a cat’s eating pattern, so the choice rests on how you feed.

Comparison table

The table uses only figures printed on each listing. A cell says “Not stated” where the listing is silent. The Gardner row uses the listing’s Large option, 0.8 gallon by two.

Dispenser	Food capacity (listing)	Water capacity (listing)	Meals and portions (listing)	Power (listing)	Bowl material (listing)	Product weight (listing)
Yuposl	21 cups / 5 L	1.32 gal / 5 L	Up to 6 meals; up to 50 portions per meal; 1/16 cup per portion	Plug-in plus 3 D-cell batteries, not included	304 stainless steel	6.83 lb
Gardner Pet	1.3 kg	0.8 gallon	Not stated	Gravity; no power cord or battery	304 stainless steel (product description)	3.88 lb
oneisall	5 L	3.5 L	Up to 6 meals; 1-16 portions per meal of 5-10 g each	Type-C plus 4 AA batteries, not included	Stainless steel, dishwasher-safe (bullet)	6.61 lb

The arithmetic behind the capacities

Five calculations use only listing figures. Each formula is written out so you can repeat it.

1. Yuposl food check: 21 cups at 0.2366 L per cup is 21 x 0.2366 = 4.97 L. That is close to the 5 L the listing states, so the two food figures agree.
2. Yuposl claim check: 5 L / 20 days = 0.25 L per day for one cat. The listing says the hopper supports one cat for up to 20 days, but it does not give the daily amount behind that figure, so treat the 0.25 L as the listing’s own implied rate.
3. oneisall claim check: 5 / 14 = 0.36 L per cat per day, where 14 is 7 days times 2 cats. The listing says the set feeds two cats for up to 7 days, so this is the implied rate for each cat.
4. oneisall maximum dispense: 6 meals x 16 portions x 5 g = 480 g per day at the smallest portion, and 6 x 16 x 10 g = 960 g per day at the largest. The listing gives both portion sizes, so the range is its own.
5. Water comparison: 5 / 3.5 = 1.43. The Yuposl water tank is about 43 percent larger than the oneisall tank, by the listing figures.

Two figures do not compare directly. The Gardner food figure is in kilograms, 1.3 kg, and its water figure is in gallons, 0.8 gallon. Converting the water gives 0.8 x 3.785 = 3.03 L. The listing does not give a density for the kibble, so there is no way to turn 1.3 kg into litres for a fair comparison.

Meals, portions and kibble size

The Yuposl listing gives up to 6 meals a day, with up to 50 portions per meal and a portion of 1/16 cup. Its largest possible daily dispense follows from those figures. One meal of 50 portions is 50 / 16 = 3.1 cups, and six such meals are 6 x 3.125 = 18.75 cups. At 0.2366 L per cup, that is 18.75 x 0.2366 = 4.4 L per day. The hopper holds 5 L, so the listing’s maximum schedule would use most, but not all, of a full hopper in a day.

The oneisall listing gives up to 6 meals a day, with 1 to 16 portions per meal of 5 to 10 g each. The figures in the arithmetic section give 480 g to 960 g as the daily range at the listing’s settings. The oneisall listing does not give a cup or litre figure for a portion, so the grams are the only unit to use with that listing.

The Gardner listing gives neither a meal count nor a portion count. Its bullets describe a widened food outlet that is meant to prevent jamming, and they say the food part is for dry food only. The listing does not say how much food one meal from the base would release, so you cannot calculate a daily dispense from it.

For kibble size, the Yuposl listing gives 2 to 15 mm, in the product table and in the directions. The oneisall and Gardner listings do not state a kibble size. Measure your kibble before you buy, and compare the largest piece with the listing’s range where one is given.

Power and backup

The Yuposl listing takes plug-in power and 3 D-cell batteries for backup. The batteries are not included. The bullets say the batteries keep the feeder working during a power outage. The listing does not say how long the batteries last, so plan to check them on a schedule.

The oneisall listing takes Type-C power and 4 AA batteries for backup, and the batteries are not included. The directions say the batteries are for backup only and recommend a corded plug. That wording matters if you rely on the feeder while you are away, because the listing treats the corded plug as the main supply.

The Gardner listing needs no power cord and no batteries. Its water and food flow by gravity, so the listing has no backup to plan for. The trade-off is that the gravity design gives no timer, so the food does not drop on a set schedule.

Cleaning and bowls

All three listings describe stainless steel somewhere, although they describe it differently. Yuposl gives 304 stainless steel for its bowls and says two isolated BPA-free stainless steel bowls separate kibble from water. Its bullets describe a water bowl that detaches and a water-tank opening of 3.43 inches. The listing says every water-contact part except the motor base is fully detachable, but it does not say whether the parts go in a dishwasher.

The oneisall listing says its stainless steel bowl is dishwasher-safe, and its bullets say all accessories are easy to remove. The Gardner listing gives 304 stainless steel in its product description, and its bullets describe a water bowl that rotates 180 degrees. It does not say whether the bowls are dishwasher-safe or whether the water bowl detaches.

A dishwasher claim on one listing does not carry over to another, and the listings do not say how often the bowls should be cleaned. For more on how bowl materials differ, see the bowl material guide. The sources we opened do not cover dishwashers or cleaning cycles for any of these units.

The three dispensers, listing by listing

The pick cards below give the reason to choose each dispenser, the case where it is the wrong pick, and one limitation. The blocks after them give the figures each listing states, and say so where a figure is missing.

How we chose

We searched Amazon.com for the keyword and took the first six ASINs in the results, in the order the page gave them. We read each listing once, on 22 October 2026. A product had to be a food and water dispenser by its title, and its listing had to state a food capacity or a water capacity. We did not rank by price or by customer feedback, and the listings were not ordered by either.

Three of the six were left out. The Amazon Basics set holds food and water, but its category is Dogs, its best-seller label reads “in Dog Automatic Feeders”, and its title names a dog as well as a cat. The two PETKIT feeders hold food only, with no water tank, and one of them is listed under Dogs. The Gardner set also names dogs in its title, but its category is Cats and its title opens with “Gravity Automatic Cat Feeder”, so we kept it on the category. The three that remain are the only food and water dispensers in the first six results that are listed under Cats.

Because the search returned six ASINs and we read those six, this roundup covers only three dispensers and does not claim to be a ranking.

What we could not verify

• Battery life. The Yuposl and oneisall listings name battery backup, but neither gives a run time, and the sources we opened do not cover run times.
• Accuracy of the portions. The listings give portion sizes in cups or grams, but none reports a measured dispense, and the sources we opened do not measure one.
• The 20-day and 7-day claims. The Yuposl listing says one cat for up to 20 days, and the oneisall listing says two cats for up to 7 days. The listings do not give the daily amount behind either figure.
• Gardner’s food volume. The listing gives 1.3 kg, which cannot be compared with the litres or gallons on the other two listings without a kibble density.
• Dishwasher use. The oneisall listing describes its bowl as dishwasher-safe, and the other two listings do not say so.
• Kibble size for two listings. Only Yuposl gives a kibble range.
• Water filter life. The Yuposl listing describes a 4-layer filter and the Gardner listing describes a built-in filter, but neither gives a replacement schedule.

Buying checklist

• Measure the kibble. Yuposl’s listing gives a 2 to 15 mm range, and the other two do not give one, so check the largest piece in your bag. Keep the rest of the bag sealed as well, and the airtight cat food storage container guide covers that step.
• Decide between timed and gravity. Yuposl and oneisall are timed, and Gardner is gravity-fed with no timer.
• Plan the batteries. Yuposl takes 3 D cells and oneisall takes 4 AA cells, and neither set is included. Gardner needs no batteries.
• Check the space. Yuposl is 14.17 inches long and 13.39 inches wide, oneisall is 7.09 by 11.81 inches, and Gardner is 21.26 inches long and 6.3 inches wide. Measure the spot before you buy.
• Choose the water size. Yuposl’s 5 L tank is the largest water figure in this set, and oneisall’s 3.5 L is the smallest.
• For more on bowls and water, see the guide to stainless steel cat bowls and the heated cat water bowl guide.

Mistakes to avoid

• Comparing kilograms with litres. Gardner’s 1.3 kg of food and its 0.8 gallon of water are different units, so do not treat them as one capacity.
• Trusting a day count. The 20-day and 7-day figures are listing claims, and neither gives the amount behind it.
• Assuming a dispenser suits wet food. Gardner says its food part is for dry food only, and the other two listings describe dry kibble. For wet food, the cat feeder for wet food guide covers that case, and the food bowl guide for messy eaters covers spill control at the bowl.
• Expecting a schedule from a gravity set. Gardner has no timer, so the food does not release at set times.
• Forgetting the batteries. Yuposl and oneisall both need batteries for backup, and neither set is included.
• Choosing by the title alone. The Gardner title names dogs and cats, and the Amazon Basics title names a dog as well as a cat, so read the bullets before you decide.

FAQ

Which cat food and water dispenser has the largest water tank?

The Yuposl listing gives the largest water figure, 5 L or 1.32 gallons. The oneisall listing gives 3.5 L, and the Gardner listing gives 0.8 gallon. The Yuposl figure is about 43 percent larger than the oneisall figure, by the division in the arithmetic section.

Can a dispenser keep food and water separate?

Yuposl says its two parts are isolated and that the stainless steel bowls keep kibble and water apart. oneisall describes a dual-compartment design that keeps food and water separate. Gardner describes a 2-in-1 set with two parts, and its bullets do not describe a divider between them.

Do these dispensers need electricity?

The Gardner listing needs no power, because it runs on gravity. The Yuposl listing needs plug-in power with 3 D-cell batteries for backup, and the oneisall listing needs Type-C power with 4 AA batteries for backup. Neither battery set is included with the unit.

How many meals can a timed dispenser give each day?

Yuposl and oneisall each give up to 6 meals a day. Yuposl allows up to 50 portions per meal, at 1/16 cup each, and oneisall allows up to 16 portions per meal, at 5 to 10 g each. The Gardner listing gives no meal count.

Is a gravity set better than a timed feeder?

The listings do not compare the two. A gravity set has no timer and no batteries, and a timed feeder has a schedule and needs power. Choose by how you feed, since the listings do not show which one a given cat prefers.

Are the bowls dishwasher-safe?

Only the oneisall listing says its stainless steel bowl is dishwasher-safe. The Yuposl and Gardner listings describe 304 stainless steel and removable parts, but they do not say whether the parts go in a dishwasher. Check the care label before you put the bowls in a machine.

Bottom line

Start with how you feed. If you need set meals, choose between Yuposl and oneisall by the water tank size and the power you can supply. If you want no timer and no batteries, the Gardner set is the one whose listing says it needs neither. For related choices, see the guide to automatic cat feeders and the guide to cat food mats.
