Let’s face it, a lot of cats are quirky about their drinking habits, with most opting for a dripping faucet over a dedicated water bowl any day. It’s not that they’re weird, they just prefer it! There are lots of reasons for it too, not only is running water fresher and cleaner, but it’s also tastier and all-around more appealing to the senses!
With that said, if your cat’s struggling to get enough H2O, it may be worth ditching the water bowl altogether and replacing it with a water fountain instead.
For those that are worried about leaving a corded electric-powered fountain running all day and all night (or are concerned about power outages and limitations surrounding portability), there are battery-operated options available.
Check out our top picks for battery-operated water fountain options for cats below!

USB Power Banks
Power banks like the ones pictured below are a great idea if you don’t want to run your USB-powered water fountain via a traditional outlet.
They essentially act as an ‘external battery pack’ for your USB-powered fountain and have a comparable battery life to traditional battery-operated units (approx. 1+ week). They’re also super easy to recharge.
Gravity Water Feeder/Fountain
Finally, whilst it’s not a “true” water fountain in that there is no constant steady flow of water, gravity water feeders are still worth a mention.
With gravity water feeders, as your cat drinks, fresh water flows into the bowl to replenish it – so the water is never stagnant when your cat uses it. Not as enticing as a free-flowing fountain but certainly fresher than a traditional water bowl!
PETSAFE Healthy Pet Gravity Water Station
Key features:
- Gravity style waterer ensures a constant supply of freshwater is always available
- No power required
- 100% cord-free
