Cat water fountains · Choose by your needs
Choose interval flow when you want circulation to start and pause on a documented schedule, rather than continuously or in response to a pet approaching. Catit PIXI Smart #43751 is an outlet-powered five-minutes-on/fifteen-minutes-paused setup; Catit PIXI UV-C #43761 offers battery bursts of twelve seconds every fifteen minutes. The cadence and available power source vary by model.

| Model | Model and power plan | Documented timing | Why it fits; tradeoff |
|---|---|---|---|
| Catit PIXI Smart Fountain 43751 | PIXI Smart #43751; outlet-powered | Geyser pattern: 5 minutes on, 15 minutes paused | A 2 L steel-top app fountain; not rechargeable. |
| Catit PIXI Stainless Steel UV-C Fountain 43761 | PIXI Stainless Steel UV-C #43761; rechargeable | 12 seconds every 15 minutes on battery | 5 L tank and supplied UVC hardware; continuous flow requires a compatible adapter. |
| PETKIT EverSweet Max 2 UVC EverSweet Max 2 UVC P4116 | EverSweet Max 2 UVC P4116; rechargeable or USB | Linked guide's battery baseline: 25 seconds each hour | Steel tray, supplied UVC pump and app; battery continuous mode is not established. |
Choose it when: The exact North American #43751 page and manual describe its Geyser interval setting as five minutes on and fifteen minutes paused while the fountain uses its supplied outlet adapter.
The limit: The interval is an outlet operating pattern, not battery use or pet detection. Its 2 L reservoir does not promise a refill interval, and app status does not establish individual-cat intake records.
Choose it when: The exact #43761 manual gives a distinct battery interval: the pump runs for 12 seconds every 15 minutes. Its separate plugged-in plan supports continuous flow.
The limit: Do not apply the maker's up-to-45-day battery statement to another mode; it is limited to timed operation. The included charging cable does not include the compatible USB-A adapter.
Choose it when: The exact P4116 guide documents a battery interval setting of 25 seconds per hour and a separate wired continuous/intermittent mode, so it illustrates why an interval claim must name its power source.
The limit: The current page's sensor advertising is not mapped to the linked guide's battery/power conditions; that combination remains unconfirmed. App/Bluetooth does not mean direct Wi-Fi or multi-cat attribution.
The three examples use different schedules and different power arrangements. Compare the maker's exact on/off behavior, refill checks and battery conditions rather than treating 'timed' as a fixed standard. If the fountain must be cordless, the dedicated battery-interval answer narrows to configurations with interval flow in that rechargeable plan.
A timed pump does not identify the pet or measure drinking. If records matter, use the tracking question that matches your goal: individual tags, app activity or camera-based profiles are different systems.
No. A physical lever changes the flow rate manually; interval circulation starts and pauses on a documented schedule.
No. The exact #43751 Geyser mode is documented in its outlet-powered setup. Its schedule does not establish a rechargeable battery plan.
No. A treatment feature does not replace the manufacturer's filter, pump, reservoir cleaning or water-changing directions.
