How does it work?
How does it work?
Hydra uses a silent pump to create a soft, bubbling stream that encourages pets to drink more. Simply fill the tank, plug into USB, and let it circulate. The upgraded version adds a soft glow that illuminates the bowl at night and prevents dry burning when the water runs low. Easy to top up, easy to clean, and always fresh.

FAQ
Is Hydra suitable for both cats and dogs?
Hydra is designed primarily for cats, but it's perfectly fine for small dogs too.
How often do I need to clean it?
We recommend a full clean once a week and topping up water daily.
Does it need to stay plugged in?
Not necessarily. Hydra is USB rechargeable, so once charged, you're free to move it where you like.

Not at all — the motor operates at just 30dB, softer than a whisper.
