Cat Water Fountains: Do They Work and How to Choose One
Cats evolved from desert animals and are not natural drinkers. They get much of their water from food, and many do not drink enough, especially on dry food. Because low water intake is linked with urinary and kidney problems, owners search for ways to encourage drinking, and fountains are a popular choice. Do they work? Often, but only if you choose and maintain them well.
Why cats like moving water
Many cats seem to prefer running or flowing water. Experts suggest that moving water is fresher and cooler, and in the wild stagnant water is more likely to be contaminated. Some cats prefer drinking from a faucet or a glass. A fountain provides a stream or a gentle bubbling surface that attracts curiosity and may increase the amount of water the cat drinks. Studies are limited, but many owners report an increase.
Why hydration matters
Cats that drink more produce more dilute urine, which may reduce the risk of crystals and stones, and support kidney function. See bladder stones and crystals in cats, feline idiopathic cystitis and chronic kidney disease in cats. A fountain is only one tool. See how to get a cat to drink more water and wet vs dry cat food.
Choosing a fountain
Material. - Stainless steel: easy to clean, durable and does not harbor bacteria. Can be noisy if the water splashes on metal. - Ceramic: heavy, stable and easy to clean when glazed. Can chip or crack. - Plastic: cheap and light, but scratches, which can harbor bacteria, and some cats develop chin acne. See cat skin allergies.
Capacity. Larger reservoirs need less frequent refilling, which helps if you travel.
Noise. Quiet pumps are better for light sleepers and sensitive cats.
Design. Open bowls with a gentle stream suit cats that like to drink from the surface. Some cats prefer a wide, shallow bowl to avoid whisker contact.
Filters. Activated charcoal filters remove tastes and odors, and must be replaced.
Parts. Choose a fountain with few parts that are dishwasher safe.
Power. Check cord safety, and keep the cord out of reach of chewers. See cat proofing your home.
Cleaning
A dirty fountain can encourage biofilm, which is a slimy layer of bacteria. Top up the water daily, and take the fountain apart weekly. Wash with hot, soapy water, scrub the pump and rinse well. Change filters according to the maker's guidance. Use only unscented soap, and rinse to remove residue. Do not use strong chemicals.
Where to put it
Cats prefer water away from food and litter, in a quiet place. Wild cats avoid drinking near where they eat. Place several water sources around the house, including a bowl and a fountain, so that your cat can choose. See cat friendly home setup and where to put the litter box.
Introducing a fountain
Leave the old water bowl in place at first. Switch on the fountain, and let the cat investigate. Reward with praise, or place a treat nearby. Some cats take a few days to adjust. If the cat avoids the fountain, try a different spot, flow level or design.
Other ways to increase water intake
- Feed wet food, which is roughly three-quarters water.
- Add warm water to wet food.
- Offer water in wide, shallow bowls.
- Keep bowls fresh.
- Try ice cubes, or a tuna-flavored water, in small amounts.
- Make sure the cat is healthy, since illness can change drinking.
When thirst is a warning
If your cat suddenly drinks much more, urinates more or loses weight, see a vet. Causes include diabetes, kidney disease and hyperthyroidism. See diabetes in cats and hyperthyroidism in cats.
Seniors and sick cats
Older cats may find it hard to reach high fountains, so use a low, wide option. See senior cat care guide.
Troubleshooting a fountain your cat ignores
If your cat refuses a new fountain, check the basics. The water may taste of plastic, so rinse and run it for a day before use. The pump may be too loud, or the flow too strong. The location may be too close to food, or in a busy area. Some cats prefer a bowl that is wide and shallow so whiskers do not touch the sides. Try a different style, and keep a regular bowl beside it. If a cat still prefers the tap, a short drink from a dripping faucet under supervision is fine, but watch water use.
Travel and power cuts
If you travel, make sure a sitter refills the reservoir, and leave a regular bowl as a backup in case the pump stops. See cat sitter vs boarding.
When to see a vet
See a vet if your cat drinks much more or less than usual. Use the US vet directory to find a clinic.
