Most of us spend an embarrassing amount of time researching the perfect grain-free kibble or raw food diet for our cats. But when it comes to hydration, we usually just turn on the kitchen sink, fill up the bowl, and hope for the best.
I see this question pop up constantly in various pet owner groups: Is it better to give cats tap water or filtered water?
It’s a crucial question. Cats are notoriously bad at drinking enough water, and chronic dehydration is a fast track to scary vet visits for kidney issues and Feline Lower Urinary Tract Disease (FLUTD). Here is a look at what your pet actually needs, and why you might want to rethink what's in their bowl.
How Much Do They Actually Need?
Dogs are pretty straightforward—they usually need about an ounce of water per pound of body weight every day. So, a 45-pound dog needs roughly 45 ounces of fresh water.
Cats are a bit trickier. A typical cat needs around 5 to 10 ounces daily. If your cat eats mostly wet food, they'll get a decent amount of that moisture directly from their meals. But if they're eating dry kibble and ignoring their water bowl, their kidneys are working overtime.
The Problem with the Kitchen Sink
Tap water is perfectly safe for us, but cats experience the world differently. Their sense of smell is roughly 14 times stronger than ours. When you smell a fresh glass of water, they smell the municipal chlorine and fluoride treatments. It’s often enough to make them turn their nose up and walk away.
Plus, if you live in an area with hard water, you are giving your cat a daily dose of excess calcium and magnesium. Over time, those heavy minerals can build up and contribute to urinary crystals.
The Electric water Fountain Phase
Once we realize tap water isn't ideal, a lot of us immediately buy an electric filtered pet water fountain. They look great on day one, but the reality sets in about a week later.
You find yourself taking it apart in the sink, trying to scrub that gross pink bacterial slime out of a tiny submersible motor. You're basically doing aquarium maintenance just to give your cat a drink, not to mention the constant hassle of buying expensive replacement carbon filters.
Why Bottled Water is the Sweet Spot
This is why so many vets and experienced pet parents eventually switch to bottled spring or purified water. It is consistent, mineral-balanced, and completely odorless. Cats naturally drink more of it because it actually tastes better.

Making Bottled Water Easy
Because bottled water is the safest and best-tasting option, so many vets and experienced pet parents eventually make the switch. The only problem? Manually pouring it into a bowl three times a day gets really old, really fast.
We got tired of cleaning slimy fountain pumps and constantly refilling bowls, which is exactly why we designed the Pumpless no filter Gravity Pet Waterer. We wanted the purity of bottled water with the convenience of an automatic fountain.
Here is how we simplified it:
-
Use Your Own Bottles: It has a universal 30mm thread. You just take a standard 1.5L water bottle, screw it on, and flip it. You instantly have a week-long supply of fresh water.
-
No Pumps, No Cords, No Filters: It runs entirely on gravity. That means zero noise, nothing to plug in, and absolutely zero replacement filters to buy.
-
Actually Easy to Clean: Because the body is 3D-printed as one seamless piece and uses a slide-out 304 stainless steel bowl or ceramic bowl, there are no hidden crevices for that pink mold to grow. You can wipe it clean in about three seconds.
If you are tired of scrubbing tiny plastic motors and worrying about your cat's urinary health, it’s time to simplify your routine.
For Pet Shop Owners & Vet Clinics
If you run a pet store, you already know the frustration of customers bringing back broken electric fountains a month after buying them.
Pet parents are actively searching for lower-maintenance, safer alternatives. Because our gravity waterers have absolutely zero electronic parts, the return rate is practically non-existent. Plus, our versatile mounting system allows you to attach the dispenser directly to your store’s display cages, creating a perfect live demo for foot traffic.
