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 harbor 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 is the overall best cat water fountain, and the cheaper Oneisall 3.5L Cord-Free Pet Water Fountain is the best choice for most people who are on a budget.
