How The Filters Work?
How The Filters Work?
The Petrooms™ uses a 3-layer active carbon filtration system designed to keep your cat’s water clean, fresh, and drinkable all day.
Each filter combines high-density activated carbon, ion-exchange media, and fine mechanical filtration to target common tap-water contaminants:
- Removes up to 99.9% of chlorine, which affects taste and can irritate sensitive digestive systems
- Eliminates 95–98% of heavy metals like lead and copper that build up in the body over time
- Filters 90–95% of pharmaceutical residues commonly found in municipal water
- Traps hair, debris, and sediment before they reach your cat’s bowl
Because water is filtered continuously as it circulates, it stays cleaner throughout the day, not just right after a refill.
To keep filtration effective, filters should be replaced regularly. With a subscription, fresh filters are delivered automatically based on your selected schedule, so your cat always has clean water without you having to remember. You can pause or cancel anytime.

“I highly recommend the KittySpout water fountain for its ease of use, my cats using it right away, the quietness of the unit and how easy it was to put together and clean compared to other water fountains.”

Dr. Alex Crowe
“In my 6 years of being a vet, I’ve seen the difference that quality products can make in a cat’s long-term health. These stand out not just for their thoughtful design, but for how well they align with what we recommend in clinical care — from hydration to enrichment. It’s refreshing to find a brand that truly understands feline needs. I recommend them wholeheartedly to my clients.”

"Actually stays clean, no slimy film"
My old plastic fountain always had that slimy layer at the bottom after a few days, no matter how much I scrubbed. The stainless steel Petrooms wipes clean in about two minutes and there's none of that bacteria buildup anymore. I've had it running for months and the pump is still whisper-quiet never given us a single problem. Filters are easy to swap and they even remind me so I never forget.

"Even my fussy cat actually drinks from it"
I'd already wasted money on two other fountains my cat sniffed them once and walked away. He only ever wanted the faucet. The Petrooms has that same gentle faucet-like flow and runs so quietly it never startles him, so now he drinks from it several times a day. Customer service was lovely too, replied to every question. Honestly the best one I've tried.

"Cats really do prefer running water"
Mine always wanted to drink from the sink faucet. Now with the Petrooms she can get fresh, filtered water whenever she wants it. I set it to movement detection so it only runs when she comes close, which saves the battery. The tank is big enough that I only refill it about once a week, even with two cats. And no cord means I can put it anywhere.

The Easiest Way to Improve Your Cat’s Health & Happiness
A simple upgrade that helps prevent dehydration and the health issues that come with it.
VET-BACKED HEALTH INSIGHT
Reduces the Risk of Kidney Issues & UTIs
According to the Journal of Veterinary Internal Medicine, one of the most common cat health problems is chronic kidney disease due to poor hydration.
- Cats naturally drink more from flowing water
- Better hydration supports kidney and urinary health
- Designed to help prevent long-term hydration-related issues
WIDE, WHISKER-FRIENDLY DESIGN
Built to Eliminate Whisker Fatigue
Many bowls force a cat’s sensitive whiskers to press against the sides, which can cause discomfort and make them avoid drinking. KittySpout’s wide, shallow bowl lets cats drink without pressure, so they stay comfortable and drink longer.
- Wide drinking surface avoids whisker overload
- Reduces hesitation caused by narrow, deep bowls
- Encourages longer, more frequent drinking sessions
FAUCET-STYLE DRINKING FLOW
Triggers Natural Drinking Instincts
Cats instinctively prefer flowing water.In the wild, moving water was safer to drink than stagnant sources. That instinct is still hardwired into cats today, which is why they’re naturally drawn to running water.
- Mimics the tap cats already try to drink from
- Encourages repeat visits throughout the day
- Helps turn drinking into a consistent habit
LARGE, LOW-MAINTENANCE CAPACITY
Up to Two Weeks of Water Per Fill
A generous reservoir means fewer refills and less daily monitoring.
- Holds enough water for 12–13 days
- Ideal for busy schedules or short trips
- Keeps fresh water available at all times
