Overview
A corded electric stainless steel pet water fountain with a 2.2 liter (74oz) capacity, made by HOOISE and sold with three replacement filters and three sponges plus the water pump included.
Metal fountains like this are often chosen over plastic ones because stainless steel resists the bacterial film and odor buildup that can develop in plastic reservoirs. Shipping with three filters and three sponges means the first replacement cycle is already covered before any separate purchase is needed.
- 2.2L / 74oz stainless steel fountain
- Corded electric pump
- Includes 3 filters and 3 sponges
- Built for cats and small animals
Who it's for
Cat and small animal owners wanting a corded, filtered fountain to encourage more drinking. Not a battery powered or cordless option, so it needs to sit near an outlet.
Strengths and trade-offs
Drawn from this product's published specifications.
- Stainless steel build resists odor buildup better than plastic
- Ships with 3 filters and 3 sponges included
- 2.2 liter capacity reduces refill frequency
- Corded electric only, no battery or cordless option
- Low voltage pump means it must stay near a power outlet
Performance notes
The circulating pump keeps water moving through the filter continuously, which is what encourages cats to drink more than they would from a still bowl and also aerates the water to slow bacterial growth between filter changes.
