"I did not believe it was going to work. I have tried every harness, even the one that goes over the nose. Many harnesses later and a lot of wasted money. But the very first time I put the leash on the front ring, the pulling STOPPED. I honestly have no idea why the front clip works, but it 100% does."

And see your cat drink more, stay properly hydrated, and feel better every day.

The Cat Fountain

Better Hydration for a Healthier, Happier Cat

The Cat Fountain

Cats naturally love moving water. In the wild, moving water was cleaner and safer to drink than still water.

But today, most cats only get a still bowl of water, and many of them avoid it. That's why almost 80% of cats don't drink enough water every day.

  • Moving water makes your cat want to drink more
  • Fresh water keeps your cat coming back all day long
  • Drinking enough water helps protect your cat from kidney problems and bladder infections

Your Cat's Water Bowl Is Dirtier Than You Think

Cat Water Bowl

Cat bowls get dirty fast. A slimy layer of bacteria grows inside the bowl from saliva, food bits, and still water. Even if you wash the bowl every day, bacteria come back within just a few hours.

That means your cat ends up drinking dirty water, which can hurt their stomach, teeth, and health over time.

  • Triple filtration removes 99.9% of bacteria, dirt, and impurities
  • Keeps your cat's water clean, fresh, and safe all day
  • Stainless steel stops slimy buildup from forming

Takes the cake

I've tried 3 different water fountains for my cats, and this one takes the cake. Previous fountains got slimy pretty quick — this one doesn't, which is a huge plus. I have 8 cats and at least 5 are picky about their water. Filters and cleaning tools are included, putting it together was quick and easy. Highly recommend!

Best cat water fountain!

This is the best cat water fountain!! I've owned several through the years. Stainless steel is so much better than plastic!! My vet suggested the fountain approximately 10 years ago. It helps maintain good kidney function as your cat ages. I give this fountain 5 stars and highly recommend.

Should have bought this sooner

I should have purchased this a long time ago for my big boy! My 20 pounder goes through a lot of water in a day and now he is drinking more and loves it. This gives me a lot of confidence about his health and the quality of the water.

Large capacity, perfect for Maine Coons

As a proud new Maine Coon parent, I've been looking for ways to keep my kitten hydrated and healthy. Large capacity (108oz/3.2L) is perfect for Maine Coons or multi-pet households! The quadruple filtration system keeps water clean, removes odors, and traps fur or dirt. Quiet operation and the stainless steel design is durable and easy to sanitize.

All 7 cats are curious and drink from it

We purchased this fountain because it's stainless steel. We have 7 cats and put out 4 water bowls, then clean and refill daily. It is very quiet and all of the cats are curious, some drink from the bowl, others from the spout. It's very attractive with the blue light in the sight window showing the water level.

Cats are drinking more and eating better

Upon it coming here I put it into service watching how long it took for them to start using. By 2:00 next day they (2 cats) were drinking the water and have been ever since. Cats seem to eat more food always wanting more later in the evening. My cats are doing great after tossing plastic water bowls out.

"I highly recommend the Maximutt fountain for its built-in UV light and triple-stage filtration — no other fountain on the market has both. My pets took to it immediately, it's whisper quiet, and it's far easier to clean than any fountain I've used."

Any Questions We Haven't Answered?

How do I know the UV sterilization actually works?
The UV light built into the Maximutt fountain operates at a wavelength proven to destroy bacteria and pathogens in water. It's the same technology used in hospitals and water purification plants, not a marketing gimmick. You'll see the UV light glowing inside the fountain when it's running.
How hard is it to clean? How often?
Easier than a bowl, honestly. Because the UV sterilization and antibacterial stainless steel surface actively resist biofilm buildup, you're not scrubbing slimy residue every few days like with plastic fountains. A quick rinse weekly and a proper clean once every 2 weeks is all it takes. The parts disassemble in seconds and are dishwasher safe, no tools, no fuss.
What exactly does the lifetime warranty cover? How do I claim it?
The lifetime warranty covers any defect in materials or workmanship, including the pump, the UV light, and all stainless steel components. If anything stops working the way it should, we replace it. Just email us at hello@maximutt.com with your order number and a brief description, and we'll take care of it. We stand behind this fountain completely because we built it to last.
What if my cat is already used to a bowl, can I transition them?
Most cats transition within 6 to 8 days, and many take to it immediately, especially cats that already show interest in running water (dripping taps, jumping on the sink). The key is placement: put the fountain near where their bowl used to be, and leave the bowl out for the first few days so they can choose. Don't force it. Curiosity does the work. Cats are wired to prefer moving water instinctively, still water in a bowl is actually unnatural for them. Once they taste the difference, most never go back.
Does this come with an AC power adapter?
Yes, the Maximutt Fountain includes an AC adapter, and it barely uses any power. It consumes less electricity than charging your phone, so it costs almost nothing to run 24/7. And unlike battery-powered fountains where old or cheap batteries can leak or swell, AC power means zero risk of that happening inside your cat's water supply.
How often do the filters need to be replaced?
We recommend changing the filter every 2 weeks to ensure fresh, clean water.
What if my cat doesn't like it?
If your cat doesn't like it or avoids it, we recommend waiting 3 to 4 days so your cat can get used to it. If they are still avoiding it, we recommend using catnip on the spout to help your cat get acquainted with it. Contact us at hello@maximutt.com and we will make sure to assist you!
What if the pump stops working?
Just send us an email at hello@maximutt.com and we will make sure you and your cat are taken care of!
Does it continuously run?
Yes, it runs continuously, and that's exactly the point. Cats are instinctively attracted to moving water because still water in the wild is often stagnant and unsafe. A constantly flowing fountain triggers that natural instinct, encouraging your cat to drink more throughout the day. This is especially important for cats on dry food, who are almost always chronically underhydrated without even showing obvious signs of thirst.
How long is the cord?
The USB cord is about 3ft.
Where does this ship from?
Our warehouses are located all around the world, so we can ship your product to you in the fastest possible way from the closest location.
Is it stainless steel?
Yes, it's made of 316 surgical grade stainless steel.
