Fountain, fixed bowl, or free-falling drip: a study measures what actually makes a cat drink
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A water fountain is often presented as the near-automatic fix for getting a cat to drink more. A study published in 2019 by Robbins, Cline, Bartges and colleagues in the Journal of Feline Medicine and Surgery tested that claim in a controlled setting. Our other equipment guidance is gathered in the cat accessories section.

The protocol: three presentations, the same cats, the same diet
Sixteen healthy laboratory cats, fed the same dry diet and individually housed with a urine-collection system, were followed while researchers varied only how water was presented: a fixed bowl, a free-falling drip-style bowl, and a circulating fountain-style bowl.
A result that cuts against the marketing
Contrary to the most repeated commercial argument, the way water was presented did not significantly change how much water the cats drank overall. Only one urinary parameter showed a significant difference: urine osmolality, higher with the circulating bowl — too isolated a marker to conclude an overall hydration benefit.
What this means for an actual purchase
A fountain remains a defensible purchase for other reasons: the water stays fresher and needs less daily manual cleaning. But our usual guidance on a cat that is not drinking enough matters at least as much as the mechanism chosen: the number of water points, keeping them away from the litter box and the food bowl, and refreshing the water often. Our guide on the cat water fountain covers the practical selection criteria, independently of this specific hydration question.
The study's limits
The sample is modest (16 cats), and the laboratory setting, with individual housing, differs from a multi-cat household with several water points. The study also does not test water temperature or added dietary moisture, two levers documented elsewhere for increasing total water intake.
Frequently asked questions
Is a water fountain useless for a cat?
No: it did not prove decisive for the volume of water drunk in this specific study, but it still helps keep water fresh and can win over individual cats reluctant to use a plain bowl.
What should I do if my cat drinks too little, fountain or not?
Adding more water points away from the litter box and food, and favouring wet food, remains more decisive than the mechanism of the container itself. Find all our guides on the cat hub.
