Why Glass?

Glass is the safest & most sanitary pet fountain material.

  • Least porous – slower to form biofilm (bacteria slime)
  • Completely inert – doesn't leach anything into their water
  • Easiest to clean – dishwasher safe and free from nooks & crannies.
  • Clear view – check water level and condition at-a-glance.

Brook's glass parts are 100% lead-free, food-grade borosilicate and soda-lime glass. The only non-glass parts are the carbon filter basket (316 stainless steel), and the pump (BPA-free, ABS plastic).

Simple Setup & Maintenance

Brook is the easiest pet fountain to set up and clean. It assembles in seconds and comes apart instantly for the dishwasher or simple hand wash. You can see the whole setup video here.

Effective Filtration

Brook features effective, no-gimmick filtration. A coarse filter ring to protect the pump, and activated carbon pulls chemical contaminants from the water. Our patent-pending PLA mesh packets make the carbon more effective while reducing bacteria growth. No gimmicks and no getting locked into an expensive and ineffective filter cartridges. Filter replacements available in 3, 6 & 12 month sets.

    The Best and Most Beautiful Fountain on the Market!

    As a certified feline behavior consultant I try out and review products all the time and this is, hands down, the best fountain I’ve ever used! [...] The Brook Fountain is the EASIEST I have ever cleaned [...] It's gorgeous and the best functioning fountain I've tried (and I've tried a bunch of them). It's hard to say who's going to love this more, you or your cats!

  • Two kittens drinking from a Brook fountain

    2 month old kittens love it

    “My 2 month kittens love this water fountain. They were a bit nervous at first but caught on fast and now drink straight from the top spout. I think it motivates them to drink more water because the fountain makes a light trickling noise and it gets their attention. I love to hear their little licks drinking the water. And it looks nice! Love that’s it’s glass. Love subtle blue light so it’s kind of a night light at night.”

  • A white cat drinking from a Brook fountain

    Best Fountain out there!

    “Love this fountain! I had a plastic one before that was impossible to clean in all its tight corners. My cat likes to drink from an open area but occasionally will drink from the fountain part. She loves this fountain! It’s silent. No loud motor like the last one. A much larger pump than others as well as a much larger bowl! It was very easy to assemble and incredibly easy to wash. Came with multiple filter replacements to get started as well. It looks beautiful and clean...”

  • Barney the dog drinking from a Brook fountain

    Beautiful, Easy to Clean, and My Pup Loves It!

    “This fountain has been such a great addition to our home! Barney loves it and I love knowing he always has fresh water.

    Setup was super easy, and the glass design not only looks beautiful but is also so easy to clean. I really like that the flow levels are adjustable, so I can set it just right for him. It even came with extra filters and cleaning tools, which makes maintenance simple.

    Overall, it’s a stylish, functional fountain that both pets and owners will appreciate. Highly recommend!”

  • A fluffy Siberian kitten beside a Brook fountain

    Smokie loves it ! 😻

    “I recently purchased Brooks pet drinking fountain, and I’m extremely happy with it. Assembly was quick and easy, and the instructions were clear. Our 4 mounts old Siberian kitten adapted to it right away, which was a huge plus. The flowing water seems to encourage more drinking, which I know is important for his health.
    One of the main reasons I chose this fountain is because it’s made of glass. My son is a veterinarian, and he always recommends glass products as the most hygienic option for pets...”

  • A tabby cat drinking from a Brook fountain

    Beautiful, quiet, easy to maintain, no allergies.

    “I’ve tried a few cat water fountains before, but this one is easily the best. The all-glass design is not only beautiful, it’s actually practical. It looks clean and modern and blends in so well that it doesn’t even feel like a pet product. It’s one of the few things I don’t mind leaving out in the open.

    One of the biggest perks is how easy it is to keep clean. With plastic or ceramic fountains, I always felt like they got grimy no matter how often I washed them...”

  • A cat drinking from a Brook fountain

    Best. Fountain. Ever.

    “Hands down, this is the best cat fountain we've ever had! We recommend it to everyone we know. It's quiet, beautiful, sturdy, well-designed, and easy to clean. We have three cats and ALL of them use it. I came across the Brook fountain when I was looking for an alternative to our plastic fountain (our vet told us that plastic could be to blame for the chin acne or older kitty, Misty, was experiencing)...”

Complete filtration: a particle filter catches debris and activated carbon purifies the water, around the Brook pump.

Brook Difference

Cleaner water that stays fresh longer

PLA mesh sachets (patent pending), made of the plant-based material used in premium teabags. Better flow: water flows more freely through the mesh, making the carbon more effective. Less biofilm: the mesh offers significantly less surface area for slime to grow, extending water freshness.

Thoughtful Design, 100% Worth the Cost

I was really hesitant about spending $90 on a cat fountain but I feel this Brook fountain is definitely worth it. Both of my cats, senior and young adult age, took to it immediately. It is super easy to clean and extremely well packaged. I appreciate the extra touches in the packaging and even the few extra parts they include like the flow limiters and glass replacement tubes. What pleasantly surprised me the most is that it is basically silent unless the bowl is low on water. I would definitely recommend Brook, even with that price point, as a healthy source of water for both cats and small dogs. The thoughtfulness in the design and minimal plastic (only the pump is plastic) make it 100% worth it. While it does have more parts than a typical plastic fountain, instructions make it simple and easy to put together.

We love it!

We love this water fountain so much. Brook really thought everything through; since it’s all glass it makes it so so easy to clean, which was the most important to me. It’s also really quiet, you can’t hear it at all! My cats really like it. I got the stand recently as well which makes it easier to carry around, and want to get the stainless steel filter holder but haven’t seen that one available yet! Can’t wait 😁

Great product and company!

I have my fountain since June 2025 and it’s perfect, my cat loves it! I just recently purchased the 12 mos replacement filters and contacted them about the small plastic clip that supports the wire to the fountain, ours has slightly cracked and I didn’t see it on the site. Almost immediately I received a response that they were sending me more free of charge. Awesome!!! Don’t hesitate to contact this company with any question or thought! -Ryan

Best water fountain!

My 3 dogs and 2 cats love this fountain! It looks so much nicer than our old stainless steel one and much easier to clean/maintain. Very affordable for how high-quality it is. So glad we made the switch! <3

Best Feline Fountain I’ve Owned

Comes as advertised - heavy glass, minimal plastic, quiet & easy to maintain.
Due to it’s relatively small capacity it does need topping off every few days. No biggie. My female cat loves it . My male cat who hunts her while she drinks seemingly hasn’t “tested the waters” as of yet ..We may have to set up a camera trap soon.

Buy this fountain if you want something clean, basically plastic-free & low maintenance. You can run it through the dishwasher! -
Serious time-saver folks.

Unsatisfactory

I live how easy it is to clean the fountain. It's easy to pull the pieces apart and hand wash or run through a dishwasher. However, the filter is useless. I fill it up with clean water and within a few hours, there are bugs or cat hair ronskemthing floating in the fountain. My cat doesn't enjoy drinking out of it, be wise something is always present in the water.

Finally a fountain easy to keep hygienic

Fifth fountain in five months since adopting a cat. Fifth time's the charm! First one that both I and my cat like. With others, she would look around, like, where is my regular fountain? I'd even put a bowl of regular water out for the transition, and she'd pass. So every experiment was slightly stressful. However, I wanted an attractive one, a quiet one, and, above all else, one that didn't get slimy! I've had it for 2 weeks and I love it. It's like a big crystal clear bowl of water -- with the benefit of it actually being a fountain, though.

Senior cat loved it immediately

My 17 year old cat started drinking from it immediately and now I regret not buying her a fountain sooner! She's the most well hydrated now than she's ever been!

Absolutely love it

Absolutely love it, but more importantly my little senior kitty does too. Easy to clean and I prefer glass over stainless or plastic. The bowl is very heavy; I wasn’t liking this at first, but I like it now that I’ve grown used to it. It’s very solid and stable. I ended buying two, one at each end of my apartment.

Picky 1yr old Loves this fountain

My rescue baby is picky with her water and likes to scoot the bowls spilling every one! This dish is too heavy. She drinks from both the fountain and the dish allowing her to choose. The pump and fountain are quiet and don’t interrupt teams calls.

Love seeing you at Cat Con 2025!

I was surprised and happy to meet Andrey at Cat Con 25. It's rare to see the founder/CEO on the show floor putting in the footwork to advertise their products! I've been a fan of Petlibro products since I got my cats Jiji and Luna back in 2021, but their DockStream and Glacier Fountains aren't the best, the DockStream would build up reddish algae-like bacteria and was an absolute pain to clean, the Glacier, which I really loved, stopped working after about 6 months of use and was discontinued. I was in search of a new fountain and at the right time found Brook Fountains at Cat Con and ordered it on the spot!

I wanted to wait and test the product for at least a month before leaving a review. The Brook Fountain is very simplistic in its design, yet it works so well! Its absolutely easy to set-up, easy to clean, and my cats absolutely love it! They love drinking from the top of the sprout and didn't need any acclamation time because they were used to electronic water fountains. The glass bowl is pretty sturdy and cleans up well, the components, like the carbon filter, are easily interchangeable, and the motor itself is easy to open up and clean!

On the other hand, there were a few things that I disliked. The main thing is the wire that plugs into the motor. I'm mainly scared that my cats will chew on it and shock themselves, or it falls into the water, but the cats haven't chewed on the wire at all. That's one thing I miss about the Petlibro DockStream, a wireless pump. When I first set up the Brook Fountain, the USB plug that came with it didn't work properly. When I plugged it in for the first time, it seemed to have short-circuited with a popping noise, and was cutting the fountain on and off. I tried using a different USB plug, and it worked with no issue. Also, I didn't put in the fountain strength reducer because my cats were not afraid of the fountain, but I noticed that without the reducer, the droplets of water would splash out of the bowl and onto the floor, slowly creating a puddle. Adding the medium reducer fixed this issue, but just an important note.

All the cons are really minor and had simple workarounds though! Overall, this has been my favorite water fountain! The clean up is fantastic, the process to order replacement parts and components is straightforward and super affordable, and the kitties absolutely love it, which is most important in my opinion! It's also refreshing to see the water in the glass because it looks so clear! It's also a great indicator showing how well the filters work, and giving a clear sign when the fountain needs to be cleaned.

Hope to see more people utilize the Brook Fountain, and also see the team at the next Cat Con, even your team member from Texas again!

Best fountain!

My dogs always used the glass water bowl over the stainless steel bowl. So I decided to try the Brook glass water fountain and it’s a WIN WIN! My dogs love it and it’s the best pet fountain I’ve ever purchased! The Fountain works great and it actually filters the water unlike others I’ve purchased.

My cat's happy, & I'm happy

My cat, Twinkles, loves her new Brook Fountain. It took about 5 minutes for her to decide to test drink from it. She loves it! I sure like the peaceful quietness of this fountain! I’ve had the fountain running for about a week now, & the water is still crystal clear. When I assembled it, I started with the low flow reducer, as suggested. I look forward to changing to the medium flow when I change the filter, and I am also going to uncover the blue light.

Thank you for designing, and selling, these pet water fountains made of glass!
