A cordless fountain built for cats who drink too little. A motion sensor wakes the pump when your cat approaches, so water is fresh and moving on demand rather than running all day, and the 4000mAh battery means no cable trailing across the kitchen floor. The 3.5L reservoir covers a multi-cat household for days.

Cat drinking from the cordless 3.5L water fountain

Cats drink more from moving water

Still water in a bowl goes ignored for hours. A fountain that wakes the moment your cat walks up keeps water fresh and interesting, which is half the battle with a cat who under-drinks.

Cordless cat water fountain on a kitchen floor with no cable

No socket, no cable

The battery runs for weeks between charges, so the fountain can sit in a hallway, bedroom or the far corner of the kitchen rather than wherever the nearest plug happens to be.

Hands lifting the lid of the cat fountain to refill it

Filtered, and easy to refill

The lid lifts off in one piece for refilling and the multi-stage filter catches hair and grit, so the water your cat drinks on Friday is as clean as Monday's.

Frequently Asked Questions

How long does a charge last?

The 4000mAh battery typically runs for several weeks in sensor mode, because the pump only starts when a pet approaches. Recharging takes a few hours over USB.

Is it quiet?

Yes. The pump is a mute design and runs in short bursts rather than continuously, so it is fine in a bedroom or a quiet flat.

How often do filters need changing?

Around every three to four weeks with one cat, sooner in a busy multi-pet home. Rinse the pump at the same time to keep the flow strong.

Can dogs use it too?

Small and medium dogs use it happily. For a large breed that empties a bowl in one go, a bigger reservoir is the better fit.

How do I clean it?

Lift the top, empty the reservoir and wash the parts in warm soapy water once a week. Everything that touches water comes apart without tools.
