Gardner Pet Gravity Feeder and Water Dispenser Review: Power-Free, but No Portion Control

Quick answer

The Gardner Pet Gravity 2-in-1 set pairs a dry-food hopper (about 1.3 kg) with a water reservoir (0.8 gallon). As the bowls empty, gravity refills them from the containers above. There is no motor, battery, app, or Wi-Fi, so there is nothing to program and nothing to fail when the power goes out.

The same design that makes it simple also limits it. Gravity feeders do not control portions. Food tops up as soon as the cat eats it. That suits a cat that eats only what it needs. It does not suit a cat that overeats, a cat on a weight plan, or a home where one cat eats everyone else’s share.

We have not tested this set.

What the set includes

According to the Gardner Pet Amazon listing:

• Food unit: a gravity hopper holding about 1.3 kg of dry food. The outlet is widened to reduce jamming. The listing says it is suitable for dry food only and not for wet food.
• Water unit: a gravity reservoir holding 0.8 gallon, with a built-in filter and a stainless steel bowl that rotates 180 degrees.
• Power: none required.
• Size: 13 x 6.7 x 12 inches.
• Extras: the brand FAQ says a long cleaning brush is included.

The listing also includes a candid note: when food runs low, dispensing may be uneven, so keep the hopper reasonably full. That is honest guidance about how gravity hoppers behave. Do not wait until the hopper is nearly empty to refill it.

Free-feeding is the decision

Before looking at capacity, decide whether free-feeding suits your cat. A gravity feeder keeps the bowl full, so the cat decides how much to eat.

That can work for:

• A healthy adult cat that grazes and keeps a steady weight.
• A short weekend away, if you already know the cat will not empty the hopper on the first day.

It is a poor fit for:

• Cats on prescription diets or weight-loss plans.
• Homes where one cat eats another’s food. Our RFID feeder guide covers selective-access bowls built for that problem.
• Cats that need meals at set times. A timed dispenser such as PETKIT Fresh Element Solo is the format designed for scheduled portions.

If your vet has asked you to measure your cat’s food, a gravity feeder works against that plan.

Capacity in context

About 1.3 kg of dry food and 0.8 gallon of water sounds like several days of supply. How many days depends on the cat, the food’s density, and whether other pets share it. The brand FAQ says the 0.8-gallon size is meant for cats, small to medium dogs, or short trips, and points multi-pet homes and large breeds to a larger XL model.

Gravity supply is not supervision. Check food and water at least daily if you can, and arrange a person to check during any absence longer than a short weekend.

Water side

The water reservoir works the same way: as the bowl empties, it refills from the bottle above. The listing describes a built-in filter and a stainless steel bowl, which is easier to clean than plastic. Unlike a powered fountain, the water does not circulate. If your cat prefers moving water, see our guide to choosing a cat water fountain.

Cleaning

Both units come apart for washing. The listing says the water reservoir is removable and the bowl is stainless steel. Gravity hoppers can collect oily residue and crumbs, so empty and wash the food container between bags of food rather than just topping it up. Stagnant water reservoirs also need regular scrubbing.

Colors

Amazon lists the set in Black (ASIN B0FVLW7C26, used for this page), Light Woodgrain (B0F383YWQH), and Yellow (B0FVLVH96M). The ASIN B0FD3VB1R6 opened the black listing when we checked.

How it compares with powered feeders

For a side-by-side of this gravity set against a timed feeder, see our gravity feeder vs automatic cat feeder comparison.

PETKIT dispensers such as Fresh Element Solo control timing and portion size but need power, setup, and an app. The HEAPETS RFID feeder controls which cat can eat but does not schedule meals. The Gardner Pet gravity set controls neither, and that is the point: it is the simplest possible supply of food and water. For a full side-by-side with a timed feeder, including capacity, failure behavior, and cleaning, read our gravity feeder vs automatic cat feeder comparison. For water that keeps moving rather than a still bowl, the Gardner Pet cordless fountain review covers a battery fountain that can sit away from an outlet.

If you portion meals by hand instead of free-feeding, a raised bowl may fit better than a gravity hopper. See how to choose raised cat bowls, or compare the Necoichi ceramic Large Flat bowl with the Necoichi tilted 2-pack.

Who it suits

• Cats that reliably free-feed without overeating.
• Owners who want a power-free backup supply alongside their normal routine.
• Homes where food and water side by side is convenient.

Who should skip it

• Any cat on a measured or prescription diet.
• Multi-cat homes with a food thief.
• Wet-food feeders. The listing says dry food only.

Limitations to keep visible

Pet Product Compass has not tested food flow, jamming, filter effectiveness, leak resistance, or cleanability. Product facts come from the Gardner Pet Amazon listing as of October 11, 2026. No official Gardner Pet website was reachable during our research.

Verdict

The Gardner Pet Gravity 2-in-1 set is a reasonable, power-free option for cats that eat sensibly on their own. If portions, timing, or food theft matter in your home, choose a timed or selective-access feeder instead.
