Catit Flower Fountain vs PETLIBRO Stainless Fountain (2026): Filters, Cleaning, Materials

Pick the Catit Flower Fountain if you want a light, plastic fountain with three flow settings and a monthly filter change; pick the PETLIBRO 3 L stainless fountain if you want a steel bowl and a quiet pump, and don't mind changing its filter twice as often. Both hold 3 L and both are sold by Amazon.com, so the choice comes down to material, filter schedule and how you like to clean. The Cornell Feline Health Center says some cats drink more from a fountain, but "individual preferences among cats for these varies," so neither is a fix for a cat that won't drink.

How we chose: we did not test either fountain; we compared the listings with each maker's filter and cleaning pages, checked September 28, 2026.

Filter and cleaning rules come from Catit's filter page, Catit's Flower Fountain cleaning guide and PETLIBRO's filter guidance.

Why a fountain at all

The Cornell Feline Health Center's hydration page says cats need "about 4 ounces of water per five pounds of lean body weight per day, so the average 10-pound cat should drink about one cup of water per day," and that cats on wet food may drink less.

Cornell lists fountains as one option, not the first: "Some cats increase their intake of water when provided with water fountains, but individual preferences among cats for these varies." It also suggests "always having fresh water available in places that they can easily access," making sure no other pet keeps a cat from the bowl, and feeding wet food.

Both makers go further on their own pages, linking fountains or filtered water to urinary health. Those are marketing claims, and we don't repeat them as fact. If your cat has a urinary or kidney problem, ask your vet how to get more water into it. This page is not veterinary advice (read more).

Plastic or stainless steel

Catit says the Flower Fountain is "made of BPA-free materials." Plastic is light, which makes the twice-monthly trip to the sink easy. Catit asks you to clean the top parts "regularly to prevent scale from settling on the fountain," and to use only warm water, a soft sponge and dish soap: "Never use aggressive detergents or an abrasive sponge." That matters for plastic, which scratches.

PETLIBRO says its bowl is BPA-free 304 stainless steel that "resists rust, corrosion, and odors." On PETLIBRO's own site, its page for the 3 L stainless fountain says "all parts can be washed in dishwasher except the pump, the pump holder, filters, water flow controller and water outlet." The Amazon listing may be a newer version of that fountain, so check the manual in the box before you load the dishwasher.

Neither maker says its material makes a cat drink more. Pick the one you will actually clean on schedule.

Filters and how often to change them

This is where the two differ most in day-to-day cost and effort.

Catit's triple action filter has three layers, per Catit: a cotton mesh outer layer that "catches stray hairs and other debris," active carbon that "helps remove foul odors and impurities," and an ion exchange resin that Catit says removes excess calcium and magnesium from tap water. Catit says: "For optimal results, we recommend replacing the filter every 30 days, or when the filter is visibly saturated." It also says Flower Fountains are "only for use with certified Catit filters," sold in packs of 2, 5 and 12.

PETLIBRO's filter is a filter with a pre-filter sponge in front of it; its site describes an activated carbon filter for this fountain. PETLIBRO says: "We recommend replacing the filters every two weeks to ensure your pet always has access to fresh water if used by one pet. For households with multiple pets, more frequent replacement is recommended." The listing's title says two filters come in the box.

So over a year with one cat, the Catit schedule is about 12 filters and the PETLIBRO schedule about 26. Check the cost of replacement filter packs before you decide.

Pro tip: write the date on the fountain's base, or set a phone reminder, the day you fit a fresh filter. Neither listing mentions a filter reminder on these two models.

Cleaning the pump

The pump is the part that clogs with hair, and both makers want it cleaned often.

• Catit says the pump "should be removed from the fountain and disassembled for cleaning on a biweekly basis," then each part rinsed with water before you put it back together.
• PETLIBRO recommends "giving the fountain interior a quick wipe once a week while thoroughly cleaning all components with dish soap," and doing it more often with more than one pet.

Both fountains plug in, and the pump sits in water. Unplug before you take either apart. Catit's listing adds that "if an extension cord is necessary, connection must be watertight and dust proof."

Noise

PETLIBRO says this fountain "runs below 30dB," and its site calls it "almost inaudible." That is PETLIBRO's figure; we did not measure it. It also says a raised pump holder and outlet design help reduce leaks and splashes.

Catit publishes no decibel figure for the Flower Fountain. Its listing says that "if the cat water fountain pump is making excessive noise, be sure to check the water level as it is most likely low."

If the fountain goes in a bedroom, PETLIBRO is the one with a published noise claim. For either, keep the water topped up: a pump running low is noisier and works harder.

Which one to buy

• For one cat and the least filter-changing: the Catit Flower Fountain, with its 30-day filter and three flow settings.
• For a steel bowl and dishwasher-safe parts: the PETLIBRO 3 L, on a two-week filter schedule.
• For a bedroom or a cat that startles easily: the PETLIBRO, for its published under-30 dB claim.
• For a cat that ignores fountains: neither. Follow Cornell's advice on fresh bowls in easy places and wet food, and ask your vet if drinking changes.

We found no CPSC recall of either fountain in the CPSC recall database on September 28, 2026. See our pet recall list before buying secondhand.

Frequently Asked Questions

Is the Catit Flower Fountain or the PETLIBRO fountain easier to maintain?

The Catit needs fewer filter changes, every 30 days per Catit, but its pump should be taken apart every two weeks. The PETLIBRO needs a new filter every two weeks with one cat, and its stainless bowl can go in the dishwasher, per PETLIBRO.

Can I use other filters in a Catit Flower Fountain?

Catit says Flower Fountains are only for use with certified Catit filters. Its triple action filter fits every full-size Flower Fountain.

Is a stainless steel fountain better than plastic for cats?

Neither maker says the material changes how much a cat drinks. PETLIBRO says its 304 stainless resists rust, corrosion and odors; Catit's plastic is BPA-free and lighter to carry. Choose the one you will clean on schedule.

How quiet is the PETLIBRO fountain?

PETLIBRO says it runs below 30 dB. We did not test it, and Catit publishes no noise figure for the Flower Fountain.
