Let your cat's approach switch a compatible fountain on without another manual check. This compact paw-shaped sensor adds 180-degree motion detection and a simple USB connection to the hydration station you already have.
Automatically detects your cat within a wide 180-degree area to help control a compatible water fountain
- manually turning the fountain on and off
- unnecessary fountain operation when pets are away
- keeping pet hydration more convenient
Your fountain now knows when your cat arrives
No more fountains humming all day for nobody. This sensor switch wakes your fountain the second a paw steps into range — and lets it rest when your cat walks away.
One sensor, one job, done well

A 180-degree eye on the bowl
The wide detection area catches an approaching cat from multiple angles instead of requiring a perfectly straight walk-up. Place the sensor toward the open approach path beside the fountain.

Paw-shaped housing that just belongs there
The molded white paw housing looks natural beside a pet fountain. Its compact form keeps the sensor visible without turning the hydration station into a pile of loose gadgets.

Plug in, walk away, done
The USB cable and connector keep setup simple. There are no tools, rewiring steps, or companion apps to manage. It is a small, practical upgrade for a compatible USB-powered fountain.

A fountain that waits for the moment
The fountain that never stops running
You either leave the fountain running while nobody is nearby or remember to switch it on whenever your cat wanders over. Either way, the routine adds noise and another small job to the day.
Enter the sensor
The paw-shaped switch watches the approach zone with a wide 180-degree detection area. Connect it to a compatible USB-powered fountain and it takes over the on-and-off moment.
A fountain that manages itself
Your cat approaches, the fountain responds, and the station rests when the area is quiet. It is a simpler way to keep a compatible fountain ready without babysitting the switch.

Questions and answers
It is made for compatible USB-powered pet water fountains. Check that your fountain accepts a USB-powered sensor switch before connecting it. This accessory upgrades a compatible fountain rather than replacing one.
The sensor covers a broad 180-degree field in front of its central detector. Point the paw housing toward the open floor where your cat normally approaches, rather than toward a wall or furniture.
The switch responds to movement in its detection area, so it is suitable for a multi-cat home when each cat approaches through the sensor's field. It does not identify individual cats.
Movement inside the detection area can activate the connected fountain. Keep the sensor focused on the fountain's immediate approach zone and away from a busy walkway.
You get two items: the paw-shaped sensor switch and its USB cable. You also need a compatible USB-powered fountain to use the upgrade.
Keep the housing and connection area positioned beside the fountain rather than in the water or splash zone. Wipe around the station during normal fountain cleaning and keep the USB connection dry.
