Classic 2.2L suits one cat. Classic 3.2L holds 45% more and has double the battery. Faucet 3.2L adds an arched tap stream for cats who drink from your sink.
30 days at home. If your cat won’t drink from it, we refund it.
Why moving water works: cats are wired to trust running water and second-guess a still bowl. The sensor wakes the pump as your cat walks up, so the stream is there every time they come looking — and silent when they leave.
A 304 stainless steel fountain on its own rechargeable battery. Fresh, filtered, moving water in the room your cat actually spends time in — no cord across the floor, no hunting for an outlet, no plastic for the water to sit in.

Excerpts from verified-purchase Amazon reviews of cordless cat water fountains; rating and count across the ten top-selling cordless fountain listings, October 2026.
Cats evolved getting most of their water from food, so the urge to drink is weak to begin with. A bowl that has sat all day, in a corner, tasting of plastic, gives them every reason to skip it. This removes each of those reasons.
A running stream reads as fresh to a cat. The sensor starts it the moment they walk up, so it is moving every single time they come to drink.
No cord means no outlet to plan around. Put it by the bed they nap on, the upstairs landing, the window they sit in. Water they pass is water they drink.
The tank is 304 food-grade stainless. No plastic taste, no scratches for slime to hide in, and it rinses clean under the tap in a minute.
Four layers catch hair and food bits, take out off-tastes with coconut-shell carbon, and soften hard tap water with ion-exchange resin.

Your cat drinks from the tap, the shower, your glass — anything except the bowl.

Moving waterThe only outlet is in the wrong room, behind the couch.
CordlessThere is a kitten or a puppy in the house who chews every cable.
No cordYour senior cat doesn’t walk to the kitchen as often as she used to.
Put it by her bedThe sensor on the pump head spots your cat and starts the stream, then stops after they leave. The longest battery life, and silent the rest of the time.
For shy cats who wait for the water to move before they come over. The stream switches on by itself on a 15-minute cycle.
Plug in the charging cable and it runs non-stop like a classic fountain, charging as it goes. Unplug and it is cordless again.

Plug in the USB cable until the light says full. That is the only time it needs a cable.
Rinse the cartridge, click it in, fill to the line in the blue window, set the head on top.
Sensor, every 15 minutes, or continuous when plugged in. Put it wherever your cat spends the day.

Set it up, put it where your cat hangs out, and give it a few days — most cats sniff it, then start drinking from it. If yours won’t, write to us within 30 days of delivery and we refund the order.
A full charge and a fresh filter, so the first week is a fair test.
Next to their favourite spot, not the food bowl. Watch who comes over.
No form and no interrogation. Tell us it wasn’t for your cat and we handle the refund.
Most do, and usually fast — moving water is exactly what cats go looking for when they drink from taps and showers. A few cautious cats need a couple of days: start in interval mode so the stream moves on its own, keep their old bowl nearby for the first days, and put the fountain where they already spend time. If yours still won’t drink from it, the 30-day guarantee covers you.
It depends on the mode. The supplier rates it at up to 60 days on standby in sensor mode, where the pump only runs while your cat drinks. Owners of cordless fountains like this typically report two to four weeks between charges with one or two cats, less in interval mode, and continuous mode is meant for when it is plugged in. The 3.2L models carry 4200mAh, twice the 2.2L’s 2000mAh. Recharging is just the USB cable, and it keeps working while it charges.
Classic 2.2L for one cat or a second fountain on another floor. Classic 3.2L for two or more cats, or if you want fewer refills and charges — it holds 45% more water and has double the battery. Faucet 3.2L if your cat already drinks from the sink or the shower: the arched chrome spout drops the stream from cat height, like a tap.
About once a month, sooner with several cats or very hard water. That is why the 6- and 12-month supplies exist — they cost far less than buying cartridges later, and you never run out. Rinse the tank and pump head each time you swap.
No. The pump is rated under 25dB, quieter than a whisper, and in sensor mode it only runs while your cat is drinking. It is fine in a bedroom.
Lift off the pump head, pull the filter, and rinse the steel tank under the tap with a little dish soap once a week. Steel doesn’t scratch the way plastic does, so there is nowhere for slime to build up. Keep the pump head itself out of standing water and wipe it rather than soaking it.
Write to us within 30 days of delivery and we refund the order. No form, no list of questions — reply to any email from us. Orders are processed in 1 to 3 business days and ship tracked, so you can see where it is from the moment it leaves.
