If you’ve ever noticed your cat ignoring a perfectly clean water bowl while making a beeline for a dripping tap, you’re not alone. Cats and dogs are instinctively drawn to moving water — it signals freshness, and frankly, a stagnant bowl sitting in the corner doesn’t do much to encourage proper hydration. A pet water fountain solves this neatly by circulating and filtering water throughout the day, keeping it cool, oxygenated, and far more appealing than a still bowl.
We’ve tested and researched the most popular pet water fountains available in the UK right now, from budget-friendly options under £25 to smart fountains with app tracking. Whether you’ve got a fussy cat, a slobbery Labrador, or a multi-pet household, there’s a fountain here that’ll suit. Below, you’ll find our honest picks along with a buying guide to help you choose the right one.

Our Top Picks
1. PETLIBRO Dockstream 2 Smart Fountain
Best for: overall top pick for most households
The PETLIBRO Dockstream 2 is comfortably the best all-round pet water fountain you can buy in the UK right now. It runs on a rechargeable battery with up to 30 days between charges, which means no trailing cables for your cat to chew through and complete freedom to place it wherever your pet prefers to drink. The stainless steel drinking tray is hygienic and dishwasher-safe, and the wireless pump design makes cleaning genuinely straightforward — no fiddly disassembly required.
What sets the Dockstream 2 apart is the companion app, which tracks your pet’s daily water intake and sends filter replacement reminders. It’s not a gimmick — if you’ve got a cat prone to urinary issues, being able to monitor hydration is genuinely useful. The pump operates at around 23 dB, which is quieter than a whisper, so it won’t disturb light sleepers or nervous pets.
At around £65–£70, it’s not the cheapest option, but the cordless convenience and smart features justify the price for most pet owners.
What we like:
- Cordless design with 30-day battery life — no cables to manage
- Stainless steel tray is hygienic and dishwasher-safe
- App tracks daily water intake and sends filter reminders
- Whisper-quiet pump at just 23 dB
Worth knowing:
- Higher price point than basic fountains
- App requires 2.4 GHz Wi-Fi (won’t connect to 5 GHz networks)
Specifications:
- Capacity: 2.5 litres
- Power: Rechargeable battery (USB-C charging)
- Material: Stainless steel tray, BPA-free body
- Noise level: ~23 dB
- Colours: White
2. Catit PIXI Smart Fountain
Best for: tech-savvy cat owners who want app control
The Catit PIXI Smart Fountain is the most feature-rich option in Catit’s excellent fountain range. It connects to the Catit app via Wi-Fi, giving you hydration tracking, water level alerts, filter change reminders, and even motion notifications so you know when your cat is drinking. For owners who worry about whether their cat is drinking enough — particularly after a vet flagging early kidney concerns — this data is invaluable.
The fountain itself has a compact, modern design that looks rather elegant on a kitchen floor. It holds 2 litres, which is fine for one or two cats but may need topping up more frequently in a multi-cat household. The triple-action filter does a solid job of removing impurities and keeping the water tasting fresh.
It’s the priciest fountain on our list at around £75–£85, and the 2-litre capacity feels a touch small for the money. But if smart monitoring is your priority, nothing else in the UK market matches it for cats specifically.
What we like:
- Full app integration with hydration tracking and alerts
- Sleek, compact design that suits modern kitchens
- Triple-action filtration keeps water clean
- Motion notifications show when your cat is drinking
Worth knowing:
- 2-litre capacity is on the small side for multi-cat homes
- Premium price — you’re paying for the smart features
- Requires mains power (no battery option)
Specifications:
- Capacity: 2 litres
- Power: Mains (USB cable)
- Material: BPA-free plastic
- Connectivity: 2.4 GHz Wi-Fi
- Colours: White, pink, green, grey
3. PetSafe Drinkwell 360 Stainless Steel Fountain
Best for: multi-pet households with cats and dogs
If you’ve got more than one pet — or a particularly thirsty dog alongside your cats — the PetSafe Drinkwell 360 is the one to get. Its 360-degree design means multiple animals can drink simultaneously from any side, which reduces guarding behaviour and means less jostling at water time. The generous 3.8-litre capacity also means you won’t be refilling it every day, even with two or three pets sharing.
The full stainless steel construction is a real plus. It’s more hygienic than plastic, resists scratches and bacteria build-up, and it’s easy to clean — just pop the main bowl in the dishwasher. The adjustable flow control lets you set the stream from a gentle trickle to a more vigorous flow, which is handy because some cats prefer barely-there movement while dogs often like a stronger stream.
It does require mains power and the pump can be a little noisier than some competitors when the water level drops, so keep it topped up. Replacement carbon filters are widely available and reasonably priced.
What we like:
- 360-degree access — perfect for multiple pets drinking at once
- Large 3.8-litre capacity reduces refill frequency
- Full stainless steel construction is hygienic and durable
- Adjustable flow control suits different pet preferences
Worth knowing:
- Pump gets noisier when water level is low
- Mains-powered only — needs to be near a socket
- Heavier than plastic alternatives, so not ideal for moving around
Specifications:
- Capacity: 3.8 litres
- Power: Mains
- Material: Stainless steel
- Flow: Adjustable with up to 5 free-falling streams
- Suitable for: Cats and small to medium dogs
4. Cat Mate Multi-Level Pet Fountain
Best for: budget-conscious owners wanting a reliable, quiet fountain
The Cat Mate Multi-Level fountain has been around for years, and there’s a good reason it keeps selling: it’s simple, reliable, and excellent value. At around £20–£30, it’s one of the most affordable pet fountains available in the UK that actually works well long-term. The three drinking levels cater to cats who prefer different heights — particularly useful for senior cats or those with arthritis who find bending down uncomfortable.
It holds 2 litres, which is perfectly adequate for one or two cats, and the polymer-carbon filter cartridge does a decent job of keeping the water clean. The pump is reasonably quiet and replacement pumps cost around £10 if yours eventually gives up after a few years of service.
The plastic construction won’t suit everyone — stainless steel is objectively more hygienic — but if you clean it regularly (once a week is ideal), it’s absolutely fine. For a first fountain or a budget pick, the Cat Mate is hard to fault.
What we like:
- Excellent value at around £20–£30
- Three drinking levels suit cats of different ages and abilities
- Simple design makes cleaning easy
- Replacement parts are cheap and widely available
Worth knowing:
- Plastic construction — less hygienic than stainless steel
- No smart features or app connectivity
- 2-litre capacity may need daily top-ups in multi-cat homes
Specifications:
- Capacity: 2 litres
- Power: Mains
- Material: BPA-free plastic
- Noise level: ~28 dB
- Suitable for: Cats and small dogs
5. Catit Flower Fountain
Best for: first-time fountain buyers and kittens
The Catit Flower Fountain is probably the most recognisable pet fountain on the market, and for good reason. It’s affordable, cheerful-looking, and genuinely effective at encouraging cats to drink more water. The removable flower top creates three different water flow settings — a gentle bubbling flow, a steady stream, or a calm surface — so you can find whatever your cat responds to best.
At under £25, it’s an easy recommendation for anyone trying a pet fountain for the first time. The 3-litre capacity is generous for the price, and replacement filters are some of the cheapest on the market. It’s also surprisingly popular with kittens, who seem fascinated by the flower attachment.
The plastic body does mean you’ll need to clean it thoroughly each week to prevent any biofilm build-up, and the pump can develop a slight hum over time. But at this price point, even if you end up replacing it after 18 months, you’ve still spent less than one premium fountain.
What we like:
- Very affordable — under £25 from most UK retailers
- Three flow settings via the removable flower attachment
- 3-litre capacity is generous for a budget fountain
- Replacement filters are cheap and easy to find
Worth knowing:
- Plastic body requires regular cleaning to prevent biofilm
- Pump can develop a hum after extended use
- No stainless steel option in the standard model
Specifications:
- Capacity: 3 litres
- Power: Mains (low voltage)
- Material: BPA-free plastic
- Flow settings: 3 (via flower top)
- Colours: White/green
6. PETLIBRO Dockstream Wireless Fountain (Original)
Best for: cordless convenience on a tighter budget
If you like the idea of the Dockstream 2 but don’t need the smart app features, the original PETLIBRO Dockstream is a brilliant middle ground. It shares the same cordless, wireless pump design — meaning no cables and easy placement anywhere in your home — but at a noticeably lower price of around £35–£45.
The 2.5-litre capacity is identical to its newer sibling, and the pump is just as quiet. You lose the app tracking and Wi-Fi connectivity, but honestly, not everyone needs those features. If you simply want a fountain that’s easy to clean, easy to place, and doesn’t trail cables across your kitchen floor, this does the job admirably.
The filtration system uses a triple-stage filter that handles hair, sediment, and odours effectively. It’s particularly well-suited to cats who like to drink in quieter spots away from the kitchen — the cordless design means you can tuck it into a hallway or bedroom without worrying about plug access.
What we like:
- Cordless design at a more affordable price than the Dockstream 2
- Wireless pump makes cleaning simple
- Quiet operation, suitable for bedrooms and offices
- Good battery life between charges
Worth knowing:
- No app connectivity or hydration tracking
- Plastic body (though food-grade and BPA-free)
- Stainless steel tray not included in the base model
Specifications:
- Capacity: 2.5 litres
- Power: Rechargeable battery (USB-C)
- Material: BPA-free plastic body
- Noise level: ~25 dB
- Colours: White
Buying Guide: How to Choose the Best Pet Water Fountain
What to Look For
The most important factors when choosing a pet water fountain are material, capacity, noise level, and ease of cleaning. Stainless steel models are the gold standard for hygiene — they resist bacteria and are generally dishwasher-safe. Plastic fountains are cheaper but require more frequent scrubbing to prevent biofilm. Capacity matters too: a single cat will be fine with 2 litres, but multi-pet households should aim for 3 litres or more.
Noise is worth considering carefully, especially if the fountain will sit in a living room or bedroom. Look for pumps rated under 30 dB — anything above that and you’ll hear a noticeable hum. Finally, think about how easy the fountain is to disassemble and clean. If it’s a chore, you’ll put it off, and a dirty fountain is worse than a clean bowl.
Types of Pet Water Fountain
There are three main types. Gravity-flow fountains use a simple pump to circulate water over a surface or through channels — the Catit Flower Fountain is a classic example. Stream fountains like the PetSafe Drinkwell create falling streams that mimic a tap, which appeals to cats who love running water. Finally, smart fountains add Wi-Fi connectivity and app tracking for owners who want to monitor hydration levels.
For most households, a standard gravity-flow or stream fountain is perfectly adequate. Smart fountains are worth the premium if your vet has flagged hydration concerns or you have a pet with a history of urinary or kidney issues.
Which Pets Benefit Most?
Cats: Fountains are particularly valuable for cats, who are notorious for not drinking enough from still water bowls. Cats with a history of urinary tract infections, kidney disease, or crystals will especially benefit from increased water intake.
Dogs: Smaller dogs and puppies enjoy fountains, though larger breeds may drink from them so enthusiastically that the water level drops quickly. The PetSafe Drinkwell 360 is the best option for households with dogs thanks to its larger capacity and robust construction.
How Much Should You Spend?
- Budget (under £30): Expect a reliable plastic fountain with basic filtration. The Catit Flower Fountain and Cat Mate Multi-Level are both excellent in this range.
- Mid-range (£30–£60): Gets you cordless designs, stainless steel options, or larger capacities. The PETLIBRO Dockstream Original and PetSafe Drinkwell 360 sit here.
- Premium (£60+): Smart features, app tracking, premium materials, and whisper-quiet operation. The PETLIBRO Dockstream 2 and Catit PIXI Smart Fountain lead this tier.
Frequently Asked Questions
How often should I clean a pet water fountain?
We’d recommend a thorough clean once a week. This means disassembling the fountain, washing all parts with warm soapy water, and scrubbing any areas where biofilm might accumulate. Stainless steel fountains can usually go in the dishwasher, which makes life easier. Replace filters according to the manufacturer’s schedule — typically every 2–4 weeks.
Are pet water fountains safe to leave running all day?
Yes, they’re designed to run continuously. The pump circulates and filters the water, keeping it fresher than a static bowl. Most modern pet fountains use low-voltage pumps that consume very little electricity — typically less than a phone charger. Just make sure the water level stays above the pump to avoid it running dry, which can damage the motor.
Will my cat actually use a water fountain?
Most cats take to fountains within a day or two, though some cautious cats may need a week. We’d suggest leaving their regular water bowl alongside the fountain initially, so they have the option of either. Many owners report that once their cat discovers the fountain, they stop using the bowl entirely.
Do I need a stainless steel fountain?
Stainless steel is more hygienic and durable than plastic, and it’s the better choice if your cat is prone to chin acne (which can be aggravated by plastic bowls). However, a well-maintained plastic fountain is perfectly safe. If budget is a concern, a plastic fountain cleaned regularly is far better than no fountain at all.
Can dogs use cat water fountains?
Small to medium dogs can use most cat fountains without any issues. Larger breeds may find smaller fountains awkward and will drain them quickly. If you have a bigger dog, look for fountains with at least 3 litres capacity and a wider drinking area, like the PetSafe Drinkwell 360.
Final Verdict
For most UK pet owners, the PETLIBRO Dockstream 2 Smart Fountain is our top recommendation — the cordless design, quiet pump, and app-based hydration tracking make it the most complete package available right now. If you’re after something more affordable, the Catit Flower Fountain remains a brilliant entry point at under £25, while the PetSafe Drinkwell 360 is the clear choice for multi-pet households needing a larger, stainless steel option.
