Overview
Stainless steel construction and a 108 ounce (3.2 liter) capacity define this AONBOY cat fountain, which adds a water level window, multi-stage filter and a silent pump.
Stainless steel construction is a step up from the plastic fountains common at this price, mainly because it resists scratching and bacterial buildup better over time, though the listing doesn't specify how the filter stages differ from a standard carbon cartridge. The water level window is a small but practical addition, letting an owner check remaining capacity without lifting the lid. At 3.2 liters, it's sized for a multi-cat household rather than a single cat's daily intake.
- 108 oz / 3.2 liter capacity
- Stainless steel, hemispherical bowl shape
- Water level window and water tap outlet
- 1 year warranty
Who it's for
Multi-cat households wanting a larger-capacity, easy-to-clean fountain with visible water level will get the most from this one. A single cat wanting something compact and light is better served by a smaller fountain.
Pros and cons
- 3.2 liter capacity suits multiple cats
- Stainless steel resists scratching better than plastic
- Water level window avoids guesswork on refills
- Listed as a silent pump
- About 1.85 lb empty, heavier than plastic fountains
- Multi-filter design likely needs recurring cartridge replacement
Performance notes
Water is drawn through a multi-stage filter by a silent pump, with a water tap outlet providing a flowing stream cats may prefer over a still bowl. The hemispherical shape and stainless steel body are built for repeated cleaning, and the window lets an owner track remaining water without opening the unit.
