The Best Cat Water Fountains of 2026: Petlibro, Petkit, Oneisall
As seen with the rise of automatic litter boxes, automatic feeders, pet trackers, and now cat water fountains, technology has made it so that we can take care of our pets without having to do as much of the manual labor.
These fancy fountains don't just make our lives easier. They can also help cats stay hydrated and live healthier. Ever wonder why your cat can't resist a dripping faucet but ignores its water bowl? In the wild, cats are drawn to moving water, since stagnant puddles can house bacteria. A water fountain plays into this natural instinct, encouraging cats to drink more. These techy fountains are also often connected to an app, which sends reminders and tracks drinking habits.
After prolonged testing, I now look for these three things when shopping for an automatic cat water fountain: a wireless pump for easier cleaning, stainless steel (or glass) construction so it's more hygienic, and a window to monitor water levels (especially if it's not connected to an app). I think the Petkit EverSweet Ultra with AI Camera Pet Water Fountain ($250) is the overall best cat water fountain, and the cheaper Oneisall 3.5L Cord-Free Pet Water Fountain ($40) is the best choice for most people who are on a budget.

This is the ultimate pet water fountain for techy pet parents. It has an AI enabled camera, a connected app to monitor drinking habits, and deep cleaning modes. Rather than an internal filter that needs frequent replacing, this fountain has a large, 5-liter freshwater tank and a 1.8-liter tank below, where, through an internal mechanism, fresh water flows to the 330-milliliter stainless steel basin and used water drains to the tank below. Using the outside buttons or the app, you can drain the water or run a deep-clean cycle that uses boiling water to sanitize the tray and internal system before refilling the reservoir with fresh water. You can also change flows between continuous, intermittent, and sensor-activated.
You can use the app to view cleaning reminders, monitor water and wastewater levels, communicate via two-way audio, view historical and live camera footage, and monitor pets’ usage. There's an additional Care+ premium subscription, which categorizes videos by cat and gives more detailed insights, but without it, I found it worked just as well, and I could still view the live feed, look back historically at the video feed, communicate, and get some insights into water intake. Maintenance with regular cleaning of this big machine requires more time and effort than some others on the list because of the internal spouts and motor, but I found it well worth it considering all of the other extra features you get with this model.
Oneisall's fountain doesn't have a connected app to track your cat's water intake, but it's an otherwise strong—and relatively inexpensive—contender. It’s made of stainless steel, features a wireless pump filter for safer and easier cleaning, and includes a cordless, rechargeable battery pack (that lasts up to 60 days), allowing the fountain to be placed anywhere in the house without being tethered to an outlet. The fountain has three water modes—sensor, intermittent, and constant (when plugged in). Plus, it has a convenient window to easily monitor water levels. The only problems are the poorly translated instructions and product information, which made the initial setup a little difficult and unclear.
