PETLIBRO Stainless vs Catit Flower Fountain
Both publish exactly 3 liters, so capacity decides nothing here. What decides it is which maker tells you what the next twelve months cost.

Everyone in this category says they tested twenty litter boxes. We have not tested any, and we say so. What we do instead: compile the published specs, read the manuals, and do the arithmetic on what this gear costs to run and how it behaves once there is more than one cat using it. Every spec is linked to the document it came from. Prices are checked daily — last verified November 4, 2026. Here is exactly how we pick.
These two come up together because they are the two names people meet first, and the comparison is usually framed as cheap plastic against pricier steel. That framing misses the only number that compounds: both of them hold exactly three liters, and only one of them tells you what the next twelve months cost.

Makers' published figures, read 2026-11-01 from the sources named below. Every 'not published' is a finding rather than a research gap -- and the two filter pack prices are PETLIBRO's own, from the same listing as the fountain.
Same three liters, different shelf
Capacity is where fountain comparisons usually start and it is a dead end here. Both makers publish three liters, within a fluid ounce of each other on their own conversions. What differs is the shape that holds it.
PETLIBRO: 10.8 x 8.1 = 87.5 sq in of floor, 4.7 in tall.
Catit: 8.3 x 7.7 = 63.9 sq in of floor, 9 in tall.
So the Catit takes 27 percent less floor (23.6 sq in less) and stands 1.9 times taller for the identical reservoir. That is a real decision in a small kitchen: the PETLIBRO wants a clear rectangle, the Catit wants headroom. It also means the Catit presents its water higher up, which suits some cats and bothers others, and neither maker publishes a drinking height.
The filter bill decides this, and the pack decides the filter bill
Our fountain running costs page found the same thing across the whole category: filters, not electricity, are what a fountain costs. This pair makes the point sharper, because PETLIBRO publishes its interval AND two different pack prices on the same listing.
PETLIBRO's own interval is every two weeks, so 26 filters a year.
4-filter set at $14.99: $3.75 a filter, x 26 = $97.44 a year.
8-filter set at $19.54: $2.44 a filter, x 26 = $63.51 a year.
Same fountain, same interval, $33.93 of difference decided by which box goes in the cart. The listing also offers a four-week upper bound for lighter use, and at that interval the 8-pack set is nearer $31.75 a year — which is the cheapest honest version of owning this fountain.
The Catit side of this table is empty, and that is the finding. Catit publishes a Triple Action Filter and no change interval; the listing shows a filter accessory without stating how many are in the box. There is no dishonest figure here, there is simply no figure — so if you buy the Catit you are agreeing to a running cost nobody has quoted you.
One publishes a wattage, the other publishes a VA rating
PETLIBRO: the adapter is rated 5 V x 1 A = 5 W, a nameplate ceiling rather than a measurement. 5 W x 24 h x 365 = 43.8 kWh, x $0.1834 = $8.03 a year.
Catit: 12 VA is apparent power at the adapter, not watts drawn, and Catit publishes no wattage. Treated as a hard ceiling: 12 W x 24 h x 365 = 105.1 kWh, x $0.1834 = $19.28 a year. The real figure is lower and nobody outside Catit knows by how much.
Either way the electricity is a rounding error against the filters: on PETLIBRO's own numbers the filters cost between 7.9x and 12.1x the power. Anyone choosing a fountain on its power draw is optimizing the small number.
Plastic, steel, and the variant Catit sells for the chin problem
The PETLIBRO tank is SUS 304 stainless and its water outlet is PP, which the maker states; the Catit LED is polypropylene throughout. Both publish BPA-free. The material argument is not about toxicity, it is about scratches: plastic scuffs, and a scuffed surface holds biofilm where a cloth cannot reach it. Our materials page runs the full comparison.
What is worth knowing before you buy the Catit is that Catit itself publishes the fix. Its own variation list on this listing offers the same 3 L Flower Fountain with a stainless steel drinking surface — a tier above the LED version, which has the nightlight and no steel. If the reason you are looking at plastic is price, that is fine. If the reason you are looking at a fountain at all is a cat with chin irritation, the LED version is the wrong one of the two.
What neither of them publishes
- A measured intake increase. The Cornell Feline Health Center includes increasing water intake in its guidance on lower urinary tract disease, which is the reason people buy these. Neither maker publishes a trial, a volume or a comparison against a bowl, and we are not going to supply one.
- Drinking height. Both publish overall height; neither publishes how high the water sits, which is the figure that matters for an arthritic cat.
- Pump replacement cost. The pump is the part that fails on every fountain in this category, and neither listing prices a spare.
- Noise, on the Catit side. PETLIBRO states below 30 dB. Catit states nothing, so the quiet comparison has one participant.
Which one to buy
The PETLIBRO stainless 3 L is the one to buy if you intend to run a fountain properly. It is the only one of the two whose year you can cost before you own it, the tank is steel rather than plastic, and the published sub-30 dB figure matters in a kitchen that is also a bedroom wall. Buy the 8-filter pack with it — the 4 Months Set is the same consumable at $2.44 a filter instead of $3.75, which is the easiest $34 a year anyone saves on a cat product. Skip it if you will not commit to the fortnightly change, or if 10.8 by 8.1 inches of clear floor is not available.
The Catit LED Flower Fountain is the one to buy to answer a different question: does this cat care about moving water at all? It is the cheaper entry, it publishes three flow settings so a cat that ignores one may take another, the water level window is genuinely useful, and it is the only one of the two with a published two-year warranty. It also takes a quarter less floor. Skip it if the cat has chin irritation (the steel-top version of the same fountain exists for that reason), or if you want to know the running cost in advance, because Catit does not publish the two figures that would let you work it out.
- Testing whether a fountain changes anything: Catit, cheapest route to an answer.
- Already convinced, want it costed: PETLIBRO plus the 8-filter set.
- Three or more cats: neither, necessarily — our multi-cat fountain page works from capacity per cat and access points rather than from brand.

PETLIBRO Stainless Steel Fountain, 3 L
PETLIBRO · Water fountain · Our score 8.7/10
#ad Price as of November 4, 2026. Prices move; we check daily. How we're funded.
The only fountain here that publishes its adapter rating, its noise figure and its filter interval -- which is everything you need to cost a year of ownership before you buy.
Published specs
| Capacity | 3 L |
|---|---|
| Tank material | Stainless steel; PP water outlet |
| Power adapter | Input 100-240 V, output 5 V / 1 A (5 W ceiling) |
| Noise | Not more than 30 dB (published) |
| Filter interval | Every 2 weeks (PETLIBRO) |
| Filter price | $14.99 per 4-pack (PETLIBRO list) |
| Dimensions / weight | 10.8 x 8.1 x 4.7 in / 1.6 lb |

Adapter output is 5 V x 1 A = 5 W, which is a nameplate ceiling, not a measurement. 5 W x 24 h x 365 = 43.8 kWh, x $0.1834 = $8.03. Filters at PETLIBRO's own $14.99 per 4-pack is $3.75 each, changed fortnightly = 26 a year = $97.44. The filters cost twelve times the electricity. Nobody puts that on the box.
What the specs favor
- Publishes the adapter rating, so running cost is computable rather than guessed
- Publishes a noise figure of 30 dB or less
- 304 stainless tank -- no plastic to scratch and harbor biofilm
- 3 L is enough for three cats between top-ups
What they don't
- Fortnightly filter changes are the real cost, at roughly $97 a year
- Plastic water outlet on an otherwise stainless fountain
- Small footprint means a determined cat can shove it around
You will not commit to a filter every two weeks. Run past the interval and a fountain is a warm, aerated, recirculating bacterial culture -- worse than a bowl you rinse daily.

Catit LED Flower Fountain, 3 L
Catit · Water fountain · Our score 7.1/10
#ad Price as of November 4, 2026. Prices move; we check daily. How we're funded.
Three flow settings and a low price -- the sensible way to find out whether a fountain changes anything in your house before spending on stainless.
Published specs
| Capacity | 3 L |
|---|---|
| Power | 120 V, 12 VA, 60 Hz, 300 mA (North America) |
| Flow settings | Three (gentle, bubbling, calm) |
| Filtration | Triple-action filter; no change interval published |
| Material | Polypropylene, published BPA-free |
| Dimensions / weight | 8.3" L x 7.7" W x 9" H / 1.8 lb |
| Extras published | Water level window, LED nightlight, petal top with water pockets |
| Published warranty | 2 years (manufacturer) |
Catit publishes 12 VA, which is apparent power at the adapter, not watts drawn -- so treat it as a hard ceiling. 12 W x 24 h x 365 = 105.1 kWh, x $0.1834 = $19.28. The real draw is lower, and Catit does not publish it. We are not going to pretend a VA rating is a wattage.
What the specs favor
- Three flow settings, so a cat that ignores one may take another
- Cheapest way to test the fountain question at all
- 3 L capacity matches the stainless models here
- Catit publishes an adapter rating, unlike PetSafe
What they don't
- Plastic, which scratches and then holds biofilm in the scratches
- 12 VA is apparent power, not a wattage -- the real draw is unpublished
- Many small parts to disassemble at cleaning time
Your cat has feline acne or a history of chin irritation. Plastic water and food vessels are the standard first thing to eliminate, and this fountain is entirely plastic.

PETLIBRO Stainless Steel Fountain Replacement Filters
PETLIBRO · Fountain filter · Our score 7.1/10
#ad Price as of November 4, 2026. Prices move; we check daily. How we're funded.
Publishes its three-layer construction and two different change intervals, which is unusual candour for a consumable -- and the gap between those two intervals is worth money.
Published specs
| Pack | 8 filters -- the listing calls it the 4 Months Set (verified 2026-11-01) |
|---|---|
| Pack price published | $19.54 for the 8-filter set against $14.99 for the 4-filter set, both on PETLIBRO's own listing |
| Construction | Cotton layer, activated carbon, ion exchange resin |
| Maker's interval | Every 2 weeks (PETLIBRO official) |
| Listing interval | Every 2 to 4 weeks depending on pets and use |
| Before first use | Soak 15 minutes and rinse to shed carbon dust |
At the official two-week interval you use 26 filters a year. At the listing's four-week upper bound you use 13. That is a two-to-one difference in the dominant running cost of owning a fountain -- and our fountain running-costs page puts filters at roughly twelve times the electricity.
What the specs favor
- Publishes the actual filter construction rather than just 'carbon filter'
- Sponges included, which are a separate purchase on some fountains
- Publishes a pre-soak instruction, which prevents carbon dust in the bowl
What they don't
- Two different published intervals from the same manufacturer
- Proprietary to PETLIBRO fountains
- The filter polishes water; it does not clean the fountain
You do not own the fountain these fit. Fountain filters are not cross-compatible, and a third-party filter that does not seat properly bypasses entirely.
