A cat water fountain keeps water moving and filtered, which some cats prefer to a still bowl. This guide compares six fountains that review sites tested hands-on, explains what to look for (material, capacity, power, filters and noise), and covers how to set one up so your cat actually uses it.
The short answer: the PETLIBRO Stainless Steel Fountain was Business Insider’s best overall and is almost all stainless steel. The Catit Flower Fountain is the familiar plastic budget option. If there is no outlet where you want the water, the cordless PETLIBRO Dockstream runs on a battery. Whatever you buy, keep an ordinary bowl out too, and clean the fountain at least weekly.
How we wrote this: the advice on bowls, placement and fountains comes from International Cat Care, VCA Animal Hospitals, the Cornell Feline Health Center, the ASPCA and PetMD articles written by veterinarians, all linked where they are used and checked on 30 October 2026. Product notes come from the makers’ pages and from hands-on tests by Cats.com, Business Insider and Wirecutter. We did not test the fountains ourselves, and we do not show prices or ratings. Whether a fountain helps cats drink more is covered in do cats need a water fountain.
Do you need a fountain?
Not necessarily. Cornell says cats should have clean, fresh water at all times, and the ASPCA says to wash and refill water bowls daily. A fountain is one way to offer water. International Cat Care says to consider running water because some cats like to drink from moving water, and VCA says a filtered fountain keeps water flowing so you do not have to leave a tap running. But not every cat takes to one, so it works best as one of several water stations rather than the only one.
What to look for
Material
International Cat Care and VCA both say cats generally prefer glass, metal or ceramic bowls to plastic. Business Insider’s vet-reviewed guide explains that plastic can scratch during cleaning, giving biofilm a place to take hold, and Wirecutter notes that ceramic and stainless are harder to scratch but that both still contain some plastic parts, such as the pump. One balancing point: International Cat Care’s caregiver guide says metal bowls are noisy, cold and reflective, which may put some cats off.
Bowl shape
International Cat Care says most cats prefer a wide, shallow bowl, so they do not have to put their head inside, and do not like their whiskers touching the sides. Look for a wide drinking area.
Capacity
Bigger fountains need refilling less often, which suits multi-cat homes, but they are heavier to carry to the sink. Keep any fountain topped up: some get noisy, and pumps can burn out, when the water runs low.
Power
Most fountains have a corded pump. VCA suggests thinking about electric cord safety. Cordless fountains run from a battery but need recharging, and Wirecutter had reliability problems with one.
Filters and cleaning
Every fountain needs taking apart and cleaning, plus new filters, as the maker recommends; International Cat Care stresses this. Business Insider’s guide says to clean a fountain at least once a week. Filter schedules vary: Catit says every 30 days for the Flower, PETLIBRO every 2 weeks, and PetSafe and Pioneer Pet every 2 to 4 weeks. Check whether the parts are dishwasher safe, because makers differ. Our how to clean a pet water fountain guide walks through it.
Noise
The International Cat Care guide says some fountains are noisier than others, which matters for noise-sensitive cats, and that a silicone or rubber mat underneath can reduce vibration.
Our picks
PETLIBRO Stainless Steel Fountain 3L: best overall
A 3 liter fountain made of 304 stainless steel, with a dishwasher-safe tank, a corded pump and adjustable flow. PETLIBRO says to replace the filter every 2 weeks. Business Insider named it best overall: easy to scrub, quiet on both flow settings, and it did not slosh when bumped. The downsides: you cannot see the water level, there is no low-water warning, and the pump can burn out if it runs dry.
Catit Flower Fountain 3L: budget pick
A 3 liter BPA-free plastic fountain with three flow settings and a water level window. Catit recommends a new filter every 30 days, and its cleaning guide says to take the pump apart and clean it every two weeks. Testers disagree on noise: Cats.com found it quiet, while Wirecutter called it one of the loudest it tested. Cats.com also notes the top is not fixed in place, so lively pets can knock it off.
PETLIBRO Dockstream: best cordless
A 2.5 liter fountain with a battery that the maker says lasts up to 30 days, a sensor mode that runs only when your cat is near, and low battery and water indicators. Cats.com named it best overall. Wirecutter dropped it after long-term testing, when one unit stopped charging and another leaked, and PETLIBRO says none of its parts are dishwasher safe.
PetSafe Drinkwell 360 Stainless: best for several pets
A round, one-gallon stainless fountain that pets can drink from on any side. The fountain goes in the top rack of the dishwasher; the pump is washed by hand. Cats.com and Wirecutter both found it hard to assemble, and Cats.com found it one of the loudest and bulky on the floor.
Pioneer Pet Raindrop Stainless 60 oz: simplest steel fountain
A low 18/8 stainless fountain that the maker says is dishwasher safe; it suggests cleaning the fountain weekly and the pump monthly. Cats.com found it one of the easiest to assemble, but it has no flow control and the glossy finish shows smudges. At 60 oz it needs refilling more often.
iPettie Tritone Ceramic: best ceramic
A 2.1 liter ceramic fountain with a bubbler, three small waterfalls and a lower bowl. Cats.com’s tester found it whisper-quiet and their cat used every drinking spot, but it is heavy, a little fiddly to set up, and some buyers report pump failures. Ceramic can also chip.
Setting up a fountain
- Introduce it slowly. International Cat Care suggests putting the fountain in place empty and switched off, adding water once your cat is comfortable, and only then turning on the pump.
- Pick a quiet spot. International Cat Care suggests a quiet place away from busy doors and machines such as washing machines, and away from the food bowl, since cats prefer not to drink next to their food. VCA says always keep water away from the litter box.
- Keep other water out. International Cat Care suggests at least one water bowl per cat plus one extra, so a fountain should be one of several water stations.
- Keep it full and clean. Top it up daily, clean it at least weekly, and change filters on the maker’s schedule.
When to call your vet
A fountain is not a treatment for anything. International Cat Care says to contact your vet if you think your cat is drinking too much or too little, and notes signs such as weight loss, increased appetite or behavior changes in cats drinking too much. PetMD‘s veterinarian author says a litter box filling faster, with heavier clumps, can be the first sign, and to book a vet visit if your cat is drinking more than normal. PetMD also covers what to try when a cat will not drink, but a cat that stops drinking should see a vet.
FAQ
Are stainless steel fountains better than plastic?
Stainless and ceramic are harder to scratch, and cats generally prefer them to plastic, according to International Cat Care and VCA. But every fountain has some plastic parts, and some cats dislike metal bowls, so watch how your cat reacts.
How often should I change a fountain filter?
Follow the maker: every 2 weeks for PETLIBRO, every 30 days for the Catit Flower, and every 2 to 4 weeks for PetSafe, Pioneer Pet and iPettie carbon filters.
Why will my cat not use the fountain?
It may be new, noisy or in the wrong place. Go back to introducing it switched off, move it somewhere quiet away from food, try a mat underneath to cut vibration, and keep a regular bowl out as well.
Can I put a cat fountain in the dishwasher?
Some parts, on some models. PetSafe and Pioneer Pet say their fountains are dishwasher safe, PETLIBRO says its stainless tank is, and PETLIBRO says no part of the Dockstream is. Pumps are always washed by hand. Check your manual.
