THE CAT CAFÉ EXPERIMENT

Do cats really prefer moving water?

Our lead ambassador Alyssa volunteers at a cat cafe in Austin, TX – she rigged up with three water stations offering a choice of bowl or fountain – and 24-hour cameras on each station.

Brook pet fountain hydration benefits

Do I need a pet fountain?

Offering your pet flowing water is one of the most important things you can do for their hydration and overall health. Indoor cats are especially susceptible to dehydration.

40% of cats over 10 years of age and up to 80% of cats over 15 are affected by Chronic Kidney Disease (CKD).

Brook glass fountain material

Is glass safe?

What do you drink out of? Brook uses 100% food-grade borosilicate & soda-lime glass. It does not leach anything into their water and is the most resistant to biofilm. See why glass is the best material for a pet fountain.

Why Glass?

Is Brook easy to clean?

Brook is the easiest fountain to clean and maintain. It comes apart in seconds. Every glass piece is dishwasher safe, or a quick hand wash. Run the pump in vinegar for 20 minutes every month or so & replace the filters on schedule.

Brook filtration system

Does it filter the water?

A pet fountain maintains water freshness through constant movement – keeping the water oxygenated and inhibiting bacteria growth. Brook has a debris filter to protect the pump, and activated carbon in mesh sachets to absorb chemical contaminants in the water. The quality of the water you start with matters most.

More About Filtration
Brook replacement filter sets

Are filters affordable?

No-gimmick filtration means Brook has the most affordable filter on the market. Available in 3, 6 & 12 month sets.

Hard water scaling on fountain surfaces

Hard water scaling?

If you have hard water, mineral deposits get left behind on surfaces when the water evaporates. Do not try to scrub it off! Spray it with regular vinegar from a spray bottle and let sit for 20 minutes. Wash it off with a soft sponge.

Cleaning the Brook fountain pump

How to clean the pump?

The easiest way to clean the pump is to put it in a cup of vinegar and let it run for ~20 minutes. Rinse thoroughly after. The pump comes apart easily for deeper cleaning – cleaning brushes are included.

Brook fountain stability and weight

Is it heavy?

“This is the first fountain our cat can’t move” is something we hear all the time. It’s about 11 lb full – heavy and stable. To make it easier for you to lift and carry, get an elevated stand.

Brook customer support

Is there customer support?

We treat customers like family (because you are). Fast, friendly & knowledgeable US-based support. Always human – no chatbots. The Brook crew is ready with answers, guidance and advice.

Real pets featured by Brook

Are the pets real?

All the pets and people we show in our photos and videos are real – no AI. The voiceovers too – that’s Alyssa, our lead ambassador. (She’s mostly human, though increasingly cat.)

The team behind Brook

Who created Brook?

A Shark-Tank-famous catrepreneur and international team of animal lovers who grew frustrated with fountain options available.

Meet the Crew
Brook continuous powered water fountain

Is it wireless?

Truly wireless fountains don’t exist. To preserve battery life, wireless fountains use a motion sensor to activate, meaning it’s a regular water bowl 99% of the time. Brook plugs into a wall outlet to run continuously.

Brook 100% Delight Guarantee

100% Delight Guarantee?

If you and your pet don’t love it for any reason – reach out. We will address your concern and work with you to resolve any issue. If in the end you decide that Brook is not for you, we will process a return (on us) and full refund. It’s that simple.

Brook glass fountain hygiene and biofilm prevention

Will it get slimy?

Slime (biofilm) forms on textured surfaces. While glass is the smoothest material, it can become textured from hard water scaling. Descale your glass regularly by spraying it with regular vinegar, letting it soak in for 15 minutes, and washing off with a soft sponge.

Not quite. While Brook was not on Shark Tank, our sister brand CAT AMAZING was. We’re the same team behind Brook.
