Pet fountains are one of the most-bought pet products on Amazon right now, and it's easy to see why: water stays moving, filtered and topped up, and a lot of cats who ignore a bowl will happily drink from a stream. The short version: get the Veken if you want the proven best seller, the stainless Veken if you want the easiest cleaning, a 7 L or bigger fountain for large dogs, and the Selene wireless fountain if there's no outlet where the bowl goes.
Every pick below is a top seller in Amazon's dog and cat fountain categories, with the details taken from each listing. If mealtime is the other worry, see our automatic dog feeders for large breeds and clever pet gadgets.
The fountains, by who they suit
1Veken 95 oz fountain: the best-selling pick
If you've seen a pet fountain in a friend's kitchen, there's a good chance it was this one. It's one of the top-selling pet fountains on Amazon, with more than forty thousand ratings and over ten thousand sold in the past month. Water circulates through a filter, and the 95 oz tank covers a cat or small dog for days between refills.
Best for: cats, small dogs and first-time fountain buyers.
Skip it if: you want metal instead of plastic; see the stainless version below.
2Veken stainless steel fountain: best for easy cleaning
The same idea with a stainless steel tray and a bigger 108 oz tank. The listing says the parts are dishwasher safe and the pump runs at about 25 dB, which is quiet enough for a bedroom. It's currently one of the fastest-selling fountains on Amazon.
Best for: owners who want the easiest cleanup.
3Stainless steel 74 oz cat fountain: best compact pick
A smaller stainless steel fountain for one or two cats, with a quiet pump (about 28 dB, per the listing) and more than twelve thousand ratings. Good for small apartments where counter or floor space is tight.
Best for: one or two cats in a small space.
4oneisall 7 L fountain: best for big dogs and multi-pet homes
Big dogs drink a lot. This stainless steel fountain holds 7 liters, so the bowl doesn't run dry while you're at work, and the listing describes a quiet pump and dishwasher-safe parts.
Best for: large dogs and homes with several pets.
5Selene wireless dog fountain: best with no cord
The cool one: a battery-powered 4 liter stainless fountain with a motion sensor, so it runs when your dog walks up and there's no cord across the floor, according to the listing. Handy if the best spot for the bowl isn't near an outlet, or if you have a cord chewer.
Best for: cord-chewing pups and spots with no outlet nearby.
6SIBAYS 15 L fountain: the biggest tank
Four gallons of water in a stainless steel fountain. That's a lot of fountain, but for two or three big dogs it means refilling far less often.
Best for: multi-dog homes and giant breeds.
72-in-1 dog water bottle: for walks and car rides
A fountain only helps at home. For walks, hikes and car rides, a bottle with a flip-out drinking tray and a separate kibble compartment keeps water handy without carrying a bowl.
Best for: long walks and road trips.
8Amazon Basics gravity food and water set: the no-pump backup
No pump, no filter, no power: a gravity waterer simply refills the bowl as your pet drinks. It's a good backup next to a fountain, or a simple option for a pet who's spooked by moving water.
Best for: a backup bowl and pets who ignore fountains.
What to look for in a pet fountain
- Tank size. Roughly 2 to 3 liters for one cat, 4 to 7 liters for a big dog, more for several pets.
- Stainless steel or plastic. Stainless is easier to scrub and many parts go in the dishwasher. Plastic is lighter and usually cheaper.
- A quiet pump. Look for a dB rating around 25 to 30 if the fountain will sit near where you sleep.
- Easy filter changes. Check that replacement filters are easy to find. Filters are the ongoing cost.
- Cord or wireless. A wireless fountain has no cord to chew or trip over, but the battery needs charging.
Where to put it
Put the fountain away from the food bowl and the litter box; many cats prefer water away from where they eat. Set it on a mat or tray to catch splashes, and keep the water level above the minimum line so the pump doesn't run dry.
Frequently asked questions
Are pet water fountains worth it?
Many cats and dogs prefer moving water to a still bowl, and a fountain keeps water filtered and fresh between refills. If your pet already drinks happily from a bowl you clean every day, a fountain is a nice extra rather than a must.
How often do you clean a pet water fountain?
Most makers suggest a full clean every week or two, and changing the filter every two to four weeks. Rinse the pump too: hair and slime build up there first. Stainless steel and dishwasher-safe parts make this much easier.
Are pet fountains loud?
Most modern fountains are quiet. Several on this list are rated at around 25 to 28 dB. If you hear gurgling, the water level is usually too low or the pump needs cleaning.
Can dogs use a cat water fountain?
Small dogs can, but big dogs empty small tanks fast and can knock them over. For a large dog, pick a big-capacity fountain like the 7 L or 15 L options.
