Cat water fountains · Choose by your needs
If you want current product references only, leave older documented models out of your comparison. Examples in the current-reference pool include Catit Mini Flower #43735 and PetSafe HydroSphere Cordless; the former is a small outlet fountain, while the latter has rechargeable sensor operation. A current reference is not a promise of seller availability, included parts, condition or price.

| Model | Exact model | Documented current-reference use | Limit |
|---|---|---|---|
| Catit Mini Flower Fountain 43735 | Catit Mini Flower #43735 | Current plastic-top, outlet-powered model | 1.5 L nominal reservoir, low 4.7 in body; own Mini filter format. |

Choose it when: Catit's exact current U.S. product page identifies the #43735 Mini Flower configuration and links its operating guide.
The limit: A current reference does not guarantee that a particular retailer has the model or exact package. The small tank does not establish days between refills.
Choose it when: PetSafe's exact current U.S. product listing and support record identify the Cordless model and its rechargeable approach-triggered operating plan.
The limit: The product's 60 oz model name is described as 1.7 L; its battery plan is motion flow, while continuous operation requires USB power. This does not establish live stock.
