Best Automatic Water Fountains For Cats
Best Automatic Water Fountains For Cats. One of the more prevalent and serious health issues I observe as a veterinarian is chronic, low level dehydration. Unlike most creatures, our furry feline companions evolved from a lineage of desert dwellers, a lifestyle that bred an extremely low instinct for drinking; as a result, our cat pets usually don’t consume sufficient water, a dietary failure that predisposes them to urinary tract diseases, kidney failure, and other significant ailments.
For instance, approximately 40 percent of cats older than age 10 will eventually suffer from Chronic Kidney Disease (CKD), and this number rises to nearly 80 percent in those age 15 or older . While feeding a good-quality wet cat food is my first choice for managing feline hydration, the most effective action you can take to get your cat to drink more is an automatic water fountain.

Why Does Your Cat Drink From the Faucet?
69% of cats who don’t get enough water do not. This is why you’re probably familiar with your cat ignoring their freshly-filled bowl for that favorite puddle on the street or from that ever-dripy kitchen faucet. This behavior isn’t as bizarre as it sounds it actually stems from an evolutionary trait.
That is because wild animals can recognize that fresh, flowing water indicates that there’s a lesser chance of waterborne diseases. Cats simply do not prefer this; instead, a continuous supply of oxygenated, filtered circulating water encourages your feline friend to drink. As part of an observational study involving 18 indoor cats, water consumption median increased by approximately 61% after introducing circulating water fountains. It’s important for our cats to drink enough, so a circulating water fountain can really make a difference for their health!
How Automatic Cat Water Fountains Work
How Does an Automatic Cat Water Fountain Work?
An automatic cat water fountain is much more than an expensive-looking dish! It is designed to work with a few basic principals to entice your feline to drink and maintain better health: Constant Circulation: This feature involves a low-power, quiet pump that transports water from a water basin, up to the drinking level, where it trickles down, repeating the process. This circulative flow attracts your cat by mirroring a natural environment, like flowing streams or springs.
Filtration: All fountains utilize a filtering process that will keep water free of any stray hairs or debris. Usually, this will consist of a foam filter that catches hair or large food particles as well as activated carbon which reduces odor and improves the overall taste of the water. Some newer models are capable of using UV or other light methods to further purify water, or some are designed with the ability to separate the clean water from waste water, offering premium-grade water that is much cleaner than static bowls.
Smart Technology: A “smart” fountain with built-in technology will notify you of the water level, monitor your cat’s consumption levels, such as drinking frequency and time, and sometimes can even determine when each individual pet has had their water intake.
What Matters Most When Choosing a Cat Water Fountain?
There are a lot of choices out there anything from basic affordable units to fancy smart fountains and it can be a little intimidating to choose. As a vet, my main priority for anything a cat might interact with is ensuring its health and safety. The key things to look at are :
1. Material: Hygiene is Key
Fountain material Perhaps the most important element to consider when it comes to your cat’s health is the fountain material.
Stainless Steel: The material is also completely pore-less, it is super long-lasting, and has no trouble when it comes to maintenance. Bacteria and slime-like bio-film-have no way to make their way around this material as easily. Many products made of this are even dishwasher safe, and they pose less risks of leaching, which plastic may do.
Ceramic: Other good porous options include this material, and maintaining a tidy unit is straightforward. These pieces can be a bit heavy making them more difficult to overthrow with a swipe from kitty’s paws. However ceramic can be more pricy and also has a risk of cracking if it hits hard surfaces.
BPA-Free Plastic: This material often gives rise to the cheapest options available to most consumers, and it is generally the most prevalent on shelves.
Unfortunately plastic products can be subject to scratching which can lead to small pockets where a bio-film will settle.
2. Capacity: The Right Size for Your Household
Water Capacity Fountain water capacity affects your refill frequency and whether it can accommodate a multi-cat family. As a general rule, cats require between 40-60ml of water per kg of their body weight every day .
- 1-2 Cats: Generally a 1.8L – 3L fountain will be appropriate.
- 3-4 Cats: At least a 3L fountain is advisable. You may wish to consider a 5L model for ease of refilling.
- 5+ Cats: Consider a large fountain of 5L or more (such as the PETKIT Ever Sweet Ultra) or having multiple fountains.
3. Filtration System: What’s in the Water?
The filtration is the magic ingredient that makes the water appealing. We looked for a fountain with a 5-layer filtering system that has an open foam layer to capture large particulates and an activated carbon filter for odors and taste . Some of the higher-end models even use UVC sterilization, capable of destroying up to 99.96 percent of bacteria, and feature “clean” and “used” water systems that keep a cat’s old water out of the fresh water tank .
4. Noise Level: Peace and Quiet
Because cats have sensitive ears, a noisy, humming pump can also be a deal-breaker, causing a skittish cat to shy away from the fountain. Good quality fountains run at almost completely silent levels- under 30 decibels . Try to view video reviews or, better yet, hear one for yourself in person to judge its noise levels.
5. Ease of Cleaning: The Key to Long-Term Use
Even the prettiest fountain in the world isn’t going to do you any good if you hate to clean it, which means you will never get to it and eventually bacteria will grow! My clients should be shopping for a fountain that breaks completely down, doesn’t have too many crevices and has dishwasher-safe parts. A fountain that is easy and quick to clean is a fountain that gets cleaned.
6. Smart Features: For the Tech-Savvy Owner
And beyond active watering-For the cat parent who is interested in more than just passive watering, smart fountains provide tremendous value. Monitoring the water intake of each individual cat through a smartphone app can even alert you to an illness in advance-A cat’s sudden inability or lack of desire to drink much is frequently one of the very first signals they aren’t feeling healthy. When this happens, you have real data to take to your vet . Multi-cat households benefit enormously from the addition of the ability of smart fountains to identify individual cats and monitor their consumption patterns .

Frequently Asked Questions (FAQs)
Should my cat have a water fountain instead of a bowl?
Most of the time, yes! Their innate curiosity and natural instinct for moving water encourage cats to drink more water, which can help ward off dehydration, kidney and urinary issues and keep the water cleaner, fresher and filtered.
My cat won’t drink from his new fountain! What do I do?
Some cats are easily intimidated and surprised by new things, and a fountain can be noisy, busy and just a little bit intimidating when it first arrives. Place it right next to his existing bowl of water. Perhaps disconnect it for a day or two so he can become accustomed to seeing it, and then plug it in so he gets used to the sound and movement. Offer some temptations nearby, such as treats or catnip.
How often should the water fountain for my cat be cleaned?
Give it time. I would recommend giving the water fountain a deep cleaning of all components with warm soapy water once per week. More often than not, if you own multiple cats, you’ll be cleaning the fountain more frequently. Top off the drinking tray with fresh water every 1-2 days.
Are plastic water fountains for cats safe?
While BPA-free plastic fountains are generally safe, they’re porous and will build up microscopic bacteria over time from wear and tear. If possible, opt for a stainless steel or ceramic fountain as these are much more hygienic and easier to clean and maintain.
Can the fountain parts be put in the dishwasher?
A number of the contemporary cat fountains are comprised of dishwasher-safe parts, but check the guide for yours. For example, the PETKIT Ever Sweet Ultra’s water tray can be placed within the dishwasher, but the pumps and bases must be hand-washed.
Must the fountain be on 24/7?
Sure. The fountain must be functioning constantly in order to keep the water circulating and filtered. That’s what entices your cat and encourages them to drink and additionally prevents bacteria from rising in stagnant water.
What occurs if the fountain loses energy?
If the fountain is switched off, the water turns into stationary and stagnant. Your cat can solely drink what water remains within the fountain’s water reservoir or tray. It’s thus really useful to keep a static bowl of water for backup.
What is biofilm, and why is it important to be aware of it?
Biofilm is a slimy layer of organic matter secreted by colonies of bacteria. Usually a pink or reddish film, biofilms can begin forming in water fountains and should be routinely cleaned out to prevent disease for your cat.
How can I determine if a water fountain is large enough for my home with multiple cats?
You can estimate water requirements by calculating the water needs of all your cats. A home with three 9-pound cats, for example, may require about 1/3 of a liter to a bit more than 1/2 liter of water per day from all sources. Choose a fountain that can hold about 3 liters as a minimum size and consider up to 5 liters to refill less often, especially when you’re not home as much.
