Best Cat Water Fountains

Stainless steel vs ceramic vs plastic cat water fountains

Material matters more for cleaning than for health. The claim you'll see most often is that plastic causes feline chin acne. The evidence for that is thin: VCA says there may be an association between plastic food and water dishes and chin acne, possibly because scratches in plastic harbor bacteria, but it also says none of the suspected causes of feline acne has been proven ^[6]. International Cat Care suggests ceramic or metal bowls over plastic as something that "can help in some cases" ^[7]. Neither cites a study, so treat a switch away from plastic as a reasonable step, not a cure.

What is better supported is preference: VCA says cats generally prefer glass, metal or ceramic to plastic ^[5].

Material notes are general to each type, not product claims. The pump and filter housing are plastic on almost every fountain, whatever the basin is made of.

Of our picks, the Veken is all plastic, the Wonder Creature has a dishwasher-safe stainless lid on a plastic body, and the PETLIBRO has a stainless drinking tray on an ABS body. If you're shopping for the best stainless steel cat water fountain specifically, check whether the water actually touches steel where the cat drinks, or only on the lid.

How often to change a cat water fountain filter, and how to clean it

VCA's rule of thumb is to clean the fountain filter weekly or as the manufacturer directs, and to clean bowls daily ^[5]. Veken's listing says to clean the pump and replace filters every one to two weeks. Use the shorter interval if you have several cats, a cat that drops food in the water, or a warm room.

The slippery coating you feel inside a neglected basin is a biofilm: bacteria growing in a film on wet surfaces. Pet water dishes are a known hot spot. A 2022 PLOS ONE study of dog bowl hygiene cites earlier household testing in which pet water dishes had the third-highest bacterial counts of 26 surfaces checked ^[10]. In the same study, washing bowls with hot water (above 160°F) or in a dishwasher lowered bacterial counts more than cold or lukewarm washing ^[10]. That study looked at food bowls, but the takeaway carries over: hot water and scrubbing, not a rinse.

A full fountain clean, step by step

1. Unplug the fountain (or switch off a cordless model) before your hands go in the water.
2. Empty it and take it apart: basin, lid or tray, pre-filter sponge, filter and pump.
3. Open the pump. Most pumps have a cover that pops off to show a small impeller (the spinning part). Pull it out and rub off hair and slime with a small brush.
4. Scrub the basin, lid and any channels with hot, soapy water, then rinse well so no soap taste is left. Put dishwasher-safe parts in the dishwasher if the maker allows it.
5. Rinse the pre-filter sponge and replace the filter on the maker's schedule.
6. Reassemble, refill with fresh water and check the water is flowing before you walk away. Veken warns never to run the pump dry.

Between full cleans, top up with fresh water every day rather than letting the level fall. A low level makes the pump noisy and, on most designs, risks running it dry.

How to get a cat to drink from a fountain

Many cats ignore a new fountain for days, or are frightened by the noise. A slow introduction usually works better than swapping the bowl overnight.

1. Keep the old bowl out. A cat that dislikes the fountain should still have water it already trusts.
2. Put the fountain somewhere quiet, such as near where the cat rests, and away from the litter box, as VCA advises ^[5]. The AAFP/ISFM feline environmental guidelines call for key resources such as food, water and toileting areas to be provided separately ^[8].
3. Start on the gentlest flow setting. The Veken has two flow modes and the Wonder Creature three, per their listings.
4. Fill it right to the line. VCA notes some cats dislike their whiskers touching the edge, and a fuller bowl can help ^[5].
5. Give it a week or two before deciding. Once the cat drinks from the fountain regularly, you can decide whether to keep the bowl as a second station. VCA suggests bowls in more than one area ^[5].

Some cats simply prefer a still bowl. A 2019 study found three of 14 cats showed individual preferences among still, circulating and falling water ^[2], so a cat that never takes to a fountain isn't doing anything wrong.

Why does my cat keep knocking over the fountain, or playing in it?

We found no research on this. The usual practical causes, and the fixes, are:

• It's light when the water is low. A half-empty plastic fountain is easy to tip. Keep it topped up, set it on a silicone mat (the Veken and Wonder Creature include one, per their listings), or choose a heavier ceramic or steel basin.
• Moving water is a toy. Some cats paw at the stream instead of drinking. A lower flow setting or a gentle bubbler is less tempting than a tall arc.
• It's in a busy spot. A fountain on a walkway gets bumped. Move it to a corner or along a wall.
• The water is warm, stale or dirty. Clean it and refill it. VCA notes some cats prefer cold water and others room temperature ^[5].

Filterless and cordless fountains

A filterless fountain skips the replaceable cartridge, so you're relying on cleaning alone. That's fine if you scrub it on the same weekly schedule. A filter catches hair and debris, but it doesn't take the place of scrubbing. A cordless model like the PETLIBRO Dockstream 2 lets you put water away from an outlet, which helps if the best quiet spot has no plug. You'll have to recharge it, and the listing's claim of up to a month per charge is the brand's own.

How much water does a cat need, and when is it too much?

Cornell's Feline Health Center gives about 4 oz of water per 5 lb of lean body weight a day ^[4]. Here's what that works out to:

Calculated from Cornell's 4 oz per 5 lb guideline ^[4]. The total includes moisture from food, so a cat on canned food will drink less from the fountain.

Drinking a lot more than usual is a reason to call your vet, not a win for the fountain. VCA lists kidney disease, diabetes, hyperthyroidism, liver disease and several other conditions among the causes of increased thirst and urination, and suggests measuring how much your pet drinks over 24 hours to help the vet ^[9]. A fountain makes that easy: fill it to the line, top it up with a measuring cup, and note how much you added. Flag a sudden change in how full the litter box is too. The PETLIBRO's app logs drinking, per its listing, but a log is not a diagnosis.

If your cat is on a timed or automatic feeder, place the fountain in a separate spot rather than right beside it, in line with the AAFP/ISFM advice to keep resources separate ^[8]. More cat feeding and water guides are in our feeding and water hub.
