Size a fountain by how much water leaves it each day. A cat drinks roughly 200 to 250 ml a day, so one cat is fine on 1.5 to 2 litres and two cats on 2 to 3 litres. A dog drinks about 50 to 100 ml per kilogram, so a 20 kg kelpie gets through one to two litres a day and wants a 3 litre tank, and a 30 kg labrador or a mixed household wants 5 to 8 litres. A big dog wants a wide, deep tray; stiff older joints want a rim 8 to 10 cm up. In summer, evaporation adds a top-up every day or two.

The Dockstream 2 is a 3 litre cordless fountain with a stainless steel drinking tray, a four-layer filter and a Wi-Fi link that logs how much water your cat takes in through the PETLIBRO app. Three litres suits two cats, or a cat and a small dog under about 10 kg, with a top-up every few days. Owners report it quiet and simple to set up, and cats drinking more with it. But the tracking that justifies the price sits behind a subscription, and reliability is the recurring theme: one fountain stopped without the app ever raising an alert, leaving cats without water, another's battery stopped holding charge inside a month, and one owner's drinking history vanished for a week. It is sold through PETLIBRO's Australian storefront with free delivery and a two-year warranty, and it charges by USB, so there is no plug question. It is the strongest fountain on this page, and the price is what that costs.

How we scored it
Each measure is marked against the category's rubric, where 10 is the best you can buy, 8 is strong, 6 is basic but sound and 4 falls short. The bars show that mark on the Top7 scale (a 6 reads as 7.0, an 8 as 8.5); the notes quote the rubric mark.
Filtration 9.6 (rubric 9.5): Four-layer filter under a stainless steel drinking tray (card): the top band; held off 10 because the card states no dry-run cut-off and one fountain stopped without an alert.
Capacity 8.5 (rubric 8): 3 litre tank (card), the 3 to 3.4 litre band; the card pitches it at two cats or a cat and a small dog, no top refill stated.
Cleaning 8.9 (rubric 8.5): Cordless tank with the pump on the base, no cable in the water, and a stainless tray (card); dishwasher safety and part count are not stated, so it stops short of 10.
Quietness 8.9 (rubric 8.5): Claimed 23 to 28 dB (card), the top of the range in the 26 to 30 band at 8, plus 0.5 because owners on the card report it quiet.
The Capsule is PETLIBRO's dog fountain: an 8 litre clear tank with a wide front tray and a semi-enclosed splash guard. Eight litres covers a 30 kg labrador for three days or a two-dog home for a long weekend, and it suits anything from a 15 kg kelpie to a 40 kg shepherd. You refill from the top without taking it apart, the five-layer filter handles hair and taste, the pump is claimed at 28 dB, and a built-in battery keeps water flowing for around 16 hours in a blackout. Owners report filling it and forgetting it, rate how quiet it is, and several bought it for a dog only to find the cats using it too. The warning is height: an owner of short-legged dogs found a shih tzu and a dachshund could not reach the bowl. It is sold through PETLIBRO's Australian storefront with free delivery. It is the one to buy for a dog household; cat-only homes do not need the size.

Filtration 8.9 (rubric 8.5): Five-layer filter in a clear plastic tank (card): the multi-layer-in-plastic band at its top; the level shows through the tank.
Capacity 10.0 (rubric 10): 8 litre tank (card), the 6-litre-plus band at 10, with a top refill that needs no disassembly; capped at 10.
Cleaning 8.5 (rubric 8): Top refill without taking it apart puts off the strip-down (card), the 8 anchor; plastic parts and a wired base with a 16-hour backup battery.

The Catit Flower Fountain is the 3 litre plastic fountain most Australian cat homes end up with, and for two cats, or a cat with a small dog, it is the strongest value on this page. Three flow settings suit picky drinkers, the petal top still lets a cat drink when the pump is off, and there is a water window with an LED nightlight. The triple-action filter combines a foam pad, activated carbon and softening resin, and replacements, including generic ones, are easy to find in Australia. Owners report cats drinking noticeably more, one saying hers stopped demanding the bathtub tap, and confirm it is quiet when full and louder as the level drops. The fiddly part is the flower stem, which pops out of position and which several owners simply leave off; the water-level window and the night light both earn their keep. It is sold and shipped by Amazon AU with a one-year warranty. It is the sensible buy, not the cleanest design.

The Drinkwell 360 is PetSafe's all-stainless fountain: a 3.8 litre round bowl with a central tower that can run up to five streams, so a dog and two cats can drink at once without jostling. It suits multi-pet homes and dogs up to about 25 kg drinking alongside cats. The stainless bowl goes in the dishwasher, a receiving ramp softens the splash, and the charcoal filter deals with taste. Owners report pets drinking more from the moving water and the visible level making it hard to run the pump dry, and at the slowest setting more than one calls it near silent. Against that, the open bowl collects dust and hair, and the reports that pull the rating down are pump failures a few months in. It is sold and shipped by Amazon AU with a two-year warranty and an Australian PetSafe phone line for spares and filters. The stainless, the capacity and the support are real, but the price is steep for what it does.

Filtration 8.1 (rubric 7.5): Charcoal filter under an all-stainless bowl (card): carbon only under stainless, the 7.5 to 8 band; the open bowl shows the level.
Capacity 9.6 (rubric 9.5): 3.8 litre bowl (card), the 3.5 to 5.9 litre band at 9, plus 0.5 because up to five streams let a dog and two cats drink at once.
Cleaning 7.4 (rubric 6.5): The stainless bowl is dishwasher safe, but the card records an open bowl that collects dust and hair and many parts to clean.
Quietness 8.5 (rubric 8): No pump figure published; more than one owner on the card calls it near silent at the slowest setting, which sets the 8 band.
Pros
+ All-stainless, dishwasher-safe bowl

Wonder Creature's 2.4 litre fountain is the budget stainless pick: a dishwasher-safe stainless top over a plastic base, three flow modes, a water window and an LED that warns when the level is low. That capacity suits one or two cats, or a small dog under 10 kg. The box includes three carbon filters, a foam pre-filter and a mat, which covers the first month or two of running cost. Owners report cats taking to it straight away and filters that are cheap and generic rather than proprietary, and longevity is what stands out: one owner is four years in on the original pump. Noise depends on the level, getting audible as it drops, and one owner had a pump fail early with support they rated poorly. It comes from a marketplace seller with free delivery and no stated warranty. It does the job for little money, and the stainless top removes the worst of the plastic hygiene problem.

DOOOB's fountain is an all-ceramic bowl with a copper spout, a 2.1 litre tank and a choice of tap or bubbling fountain flow. It is the pick for a cat with chin acne: the glaze wipes clean, holds no scratches for biofilm and takes a dishwasher cycle. At close to 3 kg it cannot be tipped by a paw. It suits one or two cats, or a small dog under 8 kg; a bigger dog would empty it daily. Owners report it close to silent and easy to clean, several having moved to ceramic after a plastic fountain became impossible to keep clean. The notes are that there is no low-water warning, and that the supplied charcoal filling strikes one owner as skimpy. The weaknesses are a basic two-stage carbon and sponge filter, the weight when you carry it to the sink, and ceramic that chips if dropped. It comes from a marketplace seller with free delivery and a two-year warranty. It is a material choice rather than an all-rounder.

PETKIT's 1.85 litre fountain is built around its wireless pump 3.0, which sits in the tank with no cable through the wall, so the whole tank lifts off the powered base for a rinse. It suits one cat, or a cat and a small dog under 8 kg, and in summer you will top it up every day or two. Owners report it whisper quiet and quick to strip down, and one whose cat had refused every other fountain says this is the one he drinks from. A practical note for Australian buyers: the supplied plug is not an Australian socket, so budget for an adapter. Where it falls short is size, and a single filter cartridge that some find hard to source outside the PETKIT store. It is sold and shipped by Amazon AU with a one-year warranty, and PETKIT has an Australian distributor. It is the cleanest design here; only the small tank holds it back.

We score each fountain on five dimensions. Filtration is what the filter stack removes and how easy replacements are to buy in Australia. Quietness is the pump noise the listing claims and what owners report at night. Ease of cleaning covers how many parts come apart, whether they are dishwasher safe and how quickly slime builds up. Capacity is the tank in litres against the pets it is meant for. Value is what that spec costs against the other six. Ratings and review counts come from Amazon AU owner feedback, prices and stock are checked daily, and we do not buy or test the products: specifications come from the listings and owner sentiment from the pattern of reviews.

Add up the daily drinking of everything using the fountain: about 200 to 250 ml per cat and 50 to 100 ml per kilogram of dog, then buy a tank holding two days of that. One cat suits 1.5 to 2 litres, two cats 2 to 3 litres, a 20 kg dog 3 litres, and a 30 kg dog or a two-dog home 5 to 8 litres. Big jaws want a wide, deep tray, stiff joints a raised rim.
Material and washability
Plastic is light and cheap but scratches, and the scratches hold the slime that builds up in any warm bowl. Stainless steel and ceramic wipe clean, go in the dishwasher and are the answer for cats with chin acne. Whatever the material, the pump is the part that clogs with hair, so look for one that pulls out without tools and comes with a brush, and plan on a full strip and wash every week.
Filters and running cost
A foam pre-filter catches hair, activated carbon removes chlorine, taste and odour, and ion-exchange resin softens hard water so scale does not coat the pump. Most brands say to change the cartridge every two to four weeks, sooner with two or more pets, so a fountain is a small subscription as well as a purchase. Before you buy, check that the brand sells replacements in Australia or that generic filters fit.
Noise and placement
Listings quote 20 to 40 dB, and the difference between the two ends is a pump you cannot hear and one you notice in a quiet bedroom. Noise rises as the water drops and air gets into the pump, so a fountain kept topped up stays quieter. Cordless fountains free you from a socket and a cable across the floor, and most run a few weeks per charge in sensor mode, at the price of remembering to charge them.
Summer heat and hard water
Heat raises drinking and evaporation together. RSPCA guidance is that pets need constant access to clean water, so on hot days top up morning and night and keep the fountain out of direct sun. Adelaide and Perth water leaves scale on pumps that Sydney and Melbourne water does not, and a monthly soak in diluted white vinegar clears it. Ants find any water bowl in summer, so stand the fountain on a mat and wipe the rim.
What the price steps buy
The lowest step here is plastic with a stainless top, a basic carbon filter and a mains cable. The middle adds full stainless or ceramic bodies, quieter pumps, bigger tanks and warranties from brands with an Australian storefront. The top step buys cordless running, a wireless pump that lifts out of the tank, and app tracking that tells you how much a kidney-prone cat drank today. Pay for the step that fixes your actual problem.
Plastic is light and cheap but scratches and holds biofilm, so owners of cats with chin acne move to stainless steel or ceramic; both go in the dishwasher. A foam pad catches hair, activated carbon removes chlorine and taste, and ion-exchange resin softens hard water. Pump noise runs from a hum you notice at night to a claimed 20 to 30 dB, and cordless models remove the cable across the floor.
To choose these seven we went through the whole Amazon Australia fountain shelf, verified each listing through Amazon's product data for stock, condition and seller, and preferred fountains sold from Australia, by Amazon itself or a brand with a local storefront and warranty.
A hot room evaporates a few hundred millilitres a day and a dry pump burns out, so a water window or low-water cut-off earns its place. Adelaide and Perth water is harder than Sydney or Melbourne water and scales up the pump; a resin filter and a monthly vinegar soak handle it. Filters are replaced every two to four weeks, so check they are sold here. Ants find pet water in summer, so use a mat, and check the box holds an Australian plug or USB lead.
Pet Water Fountains — Frequently Asked Questions
What size water fountain do I need for two cats?+
Two cats drink about 400 to 500 ml a day between them, so a 2 to 3 litre fountain gives you two or three days between top-ups with a margin for summer evaporation. Bigger is not always better, because water sitting in a large tank goes stale before it is drunk and the filter is doing more work; a 3 litre tank you refresh twice a week beats an 8 litre one left for a fortnight. Older cats like a rim a few centimetres off the floor.
How big a fountain does a 20 kg or 30 kg dog need?+
Work on 50 to 100 ml per kilogram a day, more in hot weather or after a run. A 20 kg kelpie or staffy can drink one to two litres, so a 3 litre tank needs a daily top-up and a 5 litre tank gives you a margin. A 30 kg labrador or a two-dog home should look at 8 litres. Choose a wide, deep tray for a big jaw, and a splash guard if your dog drinks like it is digging.
Are stainless steel or ceramic fountains better than plastic?+
For hygiene, yes. Plastic scratches, and scratches hold the biofilm that turns a bowl slimy in a warm Australian kitchen; it is also the usual suspect when a cat develops chin acne. Stainless steel and ceramic wipe clean, tolerate the dishwasher and hold up to a vinegar soak for scale. Plastic still wins on price and weight, and a plastic fountain that is stripped and washed weekly is perfectly safe. Many fountains split the difference with a stainless top on a plastic base.
How often should I change the filter and clean a pet fountain?+
Most makers say change the carbon filter every two to four weeks and the foam pre-filter about as often, sooner with more than one pet or a heavy shedder. Rinse the bowl and top up every day or two, and strip the whole unit, including the pump, for a wash once a week; a small brush for the pump impeller is the tool that matters. In hard-water cities a monthly soak in diluted white vinegar clears scale from the pump and spout.
Is a cordless pet water fountain worth it?+
It is if a cable across the floor is the thing stopping you putting the fountain where your pet actually drinks. Cordless fountains run a rechargeable battery for a few weeks in sensor mode, where the pump only starts when the pet approaches, and charge from a USB lead, so there is no Australian adapter question. The trade is that continuous flow drains the battery in days, and a flat battery is a still bowl. Mains fountains are cheaper for the same tank size.
Which fountain suits an apartment or a bedroom?+
Look for a claimed pump noise under 30 dB, a low-water cut-off so it does not rattle when it runs low, and a tank of 1.5 to 2 litres for a single cat so it fits on a laundry floor or beside the fridge. Wireless-pump designs, where the pump sits in the tank without a cable and the whole tank lifts off the base, are the easiest to keep clean in a small kitchen. Put it on a mat, because a drinking cat splashes.
