Cat water fountains · Choose by your needs
If you want a plastic drinking surface, decide next whether separating the tank from its motor or holding a larger outlet-fed supply matters more. Catit Easy to Clean Flower #43621 has a lift-off, electronics-free reservoir and a base-mounted motor; PetSafe Viva 140 oz has a larger nominal plastic tray and continuous outlet bubbling. Neither surface label describes every internal part.

| Model | Exact configuration | Water/power layout | Why it fits; limit |
|---|---|---|---|
| Catit Easy to Clean Flower Fountain 43621 | Easy to Clean Flower #43621 | Plastic top; lift-off reservoir and dry base motor | 2 L; retained shallow pool and local shutoff/nightlight; dishwasher permission unknown. |
| PetSafe Viva 140 oz Plastic PWW00-17922 140 oz plastic | PetSafe Viva PWW00-17922 140 oz | Plastic tray with a wired pump and continuous center bubbling | Nominal 140 oz / about 4.14 L; no battery or app feature established. |
| Catit Original Flower Fountain 43742 | Catit Original Flower #43742 | Plastic top and reservoir; submerged pump | 3 L nominal reservoir and three physical cap/flower presentations. |
Choose it when: The exact #43621 page identifies a plastic drinking surface and a separate lift-off reservoir that leaves the motor in the base.
The limit: Its 2 L reservoir is smaller than the Original Flower's 3 L. A wet rotor, connector and filter still need cleaning, and no dishwasher permission is established for this surface.
Choose it when: The exact Viva 140-oz U.S. configuration has a plastic drinking tray and a continuous outlet-powered bubbling plan with a nominal 4.14 L reservoir.
The limit: That larger nominal capacity is not a refill-time guarantee. The pump and electrical adapter require separate care, and a larger plastic tray does not meet a steel or ceramic requirement.
Choose it when: The exact Original Flower #43742 is another confirmed plastic drinking configuration, with a 3 L tank and continuous outlet circulation.
The limit: The physical presentations are not scheduled or pet-triggered modes. Its pump remains in the reservoir and its dishwasher, app and low-water-shutoff permissions are not established.
Models can pair a plastic tray or bowl with a different reservoir, pump, filter and connector. Read those component descriptions separately, particularly before machine washing. The Easy to Clean's motor stays in its dry base, but the wet rotor still needs attention; that distinction is about disassembly, not material superiority.
The Catit Flower and Viva examples are outlet-powered. If a no-outlet location matters, select battery or gravity rather than inferring cordless use from a removable part. Capacity does not establish the number of days between checks.
No. Dishwasher permission is a separate exact-component fact. The supplied top's permission may be unknown or false even when the surface is clearly plastic.
It has a motor mounted in the dry base and a removable wet rotor. The electronics-free reservoir lifts off, but the moving part and other wet components still need cleaning.
No time interval is established by capacity alone. Check the water level regularly and follow the model's care routine.
