Cat water fountains · Choose by your needs
If you're checking a specific older cat fountain or replacement setup, include documented earlier models—but verify the exact SKU, condition, parts and seller separately. Catit PIXI Ceramic #43700 has a documented 1.7 L ceramic bowl; Catit #50023 has a steel top but unknown capacity and no named flow mode; PetSafe Drinkwell 2 Gallon PWW00-16468 has a 256 oz nominal label; and the older Plastic 360 has conflicting capacity figures. Their differences matter more than age alone.
Comparison updated 29 October 2026.
| Model | Exact earlier model | What the record establishes | What remains uncertain |
|---|---|---|---|
| Catit PIXI Ceramic Fountain 43700 | Catit PIXI Ceramic #43700 | 1.7 L ceramic surface; outlet-powered continuous flow | Not listed in Catit's current U.S. fountain directory; retail availability unconfirmed. |
| Catit Stainless Steel Drinking Fountain #50023 | Catit Stainless Steel Fountain #50023 | Steel top and corded pump with USB adapter | Reservoir capacity and a named flow mode are not established. |

Choose it when: The exact #43700 product page and manual identify the earlier ceramic PIXI, its nominal 1.7 L tank, retained bowl and outlet-powered continuous setup.
The limit: Current U.S. retail availability is not confirmed. The pump is in the wet assembly; check the complete unit and exact compatible filter/top before relying on an older listing.
Choose it when: Catit's exact archived #50023 manual identifies the older stainless-steel top and pump/adapter arrangement, useful when checking a specific unit or parts listing.
The limit: No exact source reviewed establishes capacity, a named continuous/sensor/interval plan, or a current U.S. retail offer. Do not use it to satisfy a hard capacity or flow-mode minimum.
Choose it when: The exact PWW00-16468 manual and catalog identify the older two-gallon model, its continuous plugged-in pump, adjustable falling stream and filtration arrangement.
The limit: The 256 oz label is nominal, not usable volume or a refill interval. Check all parts and condition; current retail availability and exact full-body dimensions are not established.
Choose it when: The exact D360-RE guide identifies its plastic bowl, locking cone, stream-ring choices and corded continuous setup, which distinguishes it from the stainless 360 family.
The limit: Older official capacity figures conflict and the exact guide does not settle them. Do not use this listing to meet a hard reservoir minimum or infer its current availability.
Older product names can resemble current or revised models. Match the stamped model/SKU to the exact manual and product record, then verify the delivered tank, pump, lid, adapters, shields and filters. Do not assume a newer sibling's parts or specifications carry over.
The included older references are useful for checking an existing fountain or a particular used/listed offer. They do not say that a unit is currently sold, new, complete or supported in every region. Confirm condition, seller, compatibility and parts independently.
No. The age/reference control broadens the documented comparison only. It says nothing about live stock, seller condition, price or replacement-part availability.
Its exact sources do not confirm reservoir capacity or a specific flow mode. Unknown does not satisfy a hard minimum; choose a better-documented model if those conditions are essential.
No. Two U.S. gallons are documented as 256 U.S. fl oz, about 7.57 L by conversion, below 10 L. Its nominal label is not measured usable fill.
