Do Cats Need a Water Fountain? What the Research Says

Cat water fountains are often sold as the answer to a cat that does not drink enough. This page looks at what the research actually says about fountains and water intake, which cats are most likely to benefit, what works better for hydration, and what a fountain asks of you in cleaning and upkeep.
The short answer: no, most cats do not need a water fountain. In controlled studies, cats on average drank about the same amount from a fountain as from a bowl, and urine concentration did not change. Some individual cats clearly prefer moving water, and for them a fountain is a good buy. If your goal is more water in your cat, wet food has the stronger evidence, and fresh water in several clean bowls around the home is a free first step.
How we wrote this: this page is based on peer-reviewed studies in the Journal of Feline Medicine and Surgery and the Journal of Animal Science, the Cornell Feline Health Center and the brands’ own product pages, each linked where it is used. We have not tested these fountains ourselves. It is general information, not veterinary advice: if your cat has kidney or urinary disease, ask your vet how to raise its water intake.
Fountain vs bowl at a glance
| Water bowl | Water fountain | |
|---|---|---|
| Effect on intake (average cat) | Baseline | About the same in most studies |
| Cats that prefer it | Many cats are happy with a wide, shallow bowl | Some cats clearly prefer moving water |
| Cost | Low | Higher, plus replacement filters |
| Cleaning | Wash and refill daily | Daily top-up, regular full clean, filter changes |
| Power | None | Needs an outlet; pump must not run dry |
| Noise | Silent | Low hum or trickle |
What the research says
Three studies have measured how much cats drink from fountains compared with bowls.
- Grant, 2010. In a study of 13 healthy cats in the Journal of Feline Medicine and Surgery, cats drank somewhat more from a fountain than from a bowl (31.6 versus 22.9 ml per kg per day), but their urine was no more dilute. One cat developed excessive grooming, vomiting and refused to drink from the fountain. The author concluded that the fountain failed to substantially increase water intake and dilute urine.
- Robbins and colleagues, 2019. A study of 14 cats in the same journal compared a still bowl, a circulating bowl and a free-falling fountain. Average daily water intake and urine volume did not differ between them. Three individual cats did show a clear preference, each for a different bowl. The authors advised using other ways to increase water intake, beyond special water bowls, when a cat needs to drink more.
- A 2026 review of 32 studies in the Journal of Animal Science found that diet format (wet or dry), protein, salt, certain additives and water viscosity affected how much cats drank, while water source type (still or flowing) did not. It suggested that cats needing more water would likely benefit from a wet or other high-moisture diet.
The picture is consistent: a fountain is not a reliable way to make the average cat drink more. But averages hide individual cats, and the Cornell Feline Health Center notes that many cats prefer to drink from water fountains. If your cat paws at the tap, drinks from dripping faucets or ignores its bowl, it may be one of them.
Which cats might benefit from a fountain
- Cats that seek out running water, such as tap drinkers and cats that drink from the shower.
- Cats that leave their bowl untouched even when it is clean and fresh.
- Homes where water sits for long periods, since a fountain keeps water moving and filtered between your top-ups.
- Cats your vet wants drinking more, as one of several options to try, alongside diet changes your vet recommends.
A fountain is a test, not a promise. Watch whether your cat actually uses it, and keep a normal bowl out while it gets used to the new one. The Grant study shows that a few cats dislike fountains.
Better ways to help a cat drink more
- Wet food. The 2026 review found diet format had a clear effect on water intake, and it suggested a wet or high-moisture diet for cats that need more water. Talk to your vet before changing the diet of a cat with a health condition.
- Several water stations. Cornell says clean bowls with fresh water in several places in the home will encourage cats to drink more.
- Fresh water every day. The Cornell Feline Health Center lists clean, fresh water at all times among its steps to reduce lower urinary tract disease.
- Try a different bowl. If your cat ignores a deep or narrow bowl, a wide, shallow one is worth a try, such as the Dr. Catsby Whisker Relief Bowl. Our bowls and feeders buying guide covers materials and shapes.
- Water away from the litter box. Cornell advises placing the litter box away from the feeding area, and the same logic applies to water.
What a fountain asks of you
A fountain only helps if it stays clean. Because the water recirculates, a neglected fountain can be worse than a fresh bowl.
- Top up daily. A 3 liter fountain can run low quickly in a multi-cat home, and many pumps must not run dry.
- Change the filter on schedule. Catit says to replace the filter in its Flower Fountain every 30 days.
- Clean the whole fountain regularly, including the pump, on the schedule in the manual. Slime builds up in tubes and corners.
- Pick a material you can scrub. Stainless steel has fewer scratches and crevices than plastic and is easier to keep clean.
- Plan for the cord, and keep it out of reach of cats and dogs that chew.

When drinking habits mean a vet visit
A change in how much your cat drinks can be a sign of illness. The Cornell Feline Health Center explains that as the kidneys lose their ability to concentrate urine, cats may urinate more and drink more water to compensate. If your cat suddenly drinks much more or much less than usual, or you are filling the bowl far more often, tell your vet. Our guide on how often to change cat litter covers the litter box signs that also need a vet.
FAQ
Do cats drink more from a water fountain?
On average, not by much. One study found cats drank somewhat more from a fountain but their urine was no more dilute, and another found no difference in intake between still, circulating and free-falling bowls. Some individual cats do prefer a fountain.
Do vets recommend water fountains for cats?
The Cornell Feline Health Center notes that many cats prefer them. Research suggests wet food has a stronger effect on water intake, so ask your vet which to try first.
Are water fountains bad for cats?
Not if they are kept clean. A dirty fountain recirculates slime, so it needs filter changes and regular cleaning. A few cats dislike fountains, so keep a normal bowl available too.
How often should you clean a cat water fountain?
Top it up daily and follow the manual for full cleaning. Catit, for example, says to replace the Flower Fountain filter every 30 days. Clean more often if you see slime or your cat stops drinking from it.
What is the best way to get my cat to drink more water?
Feed wet food if your vet agrees, offer fresh water in several clean, wide bowls around the home, and try a fountain if your cat likes moving water.
