Join 10,000+ Cat Owners Who Have Made the Switch to Smarter Hydration

We recommend replacing the filter every 7 days for optimal freshness.

Each filter captures hair, dust, litter particles, and microscopic debris that would otherwise accumulate in the water — the same contaminants that drive cats to reject their water source.

With a quarterly subscription ($57 every 90 days), fresh filters are delivered to your door automatically at the lowest per-filter cost. You'll never have a gap where your cat is drinking through a spent filter, and you can cancel or pause anytime.

Absolutely. The color is applied to the exterior surface only — underneath is the same 304 medical-grade stainless steel (18% chromium, 8% nickel) used in surgical instruments.

Every water-contact surface is uncoated stainless steel. The finish is BPA-free, non-toxic, and won't chip, peel, or leach into the water. Your cat drinks from pure, non-porous steel — the color is purely cosmetic.

96% of cats drink more from Marlene’s Fountain compared to a still bowl.

Here's why: cats evolved to associate moving water with safety and still water with contamination. The faucet-style spout mimics the falling stream that triggers their instinctual drinking response. The water also picks up oxygen on the way down, making it taste fresher and cooler.

And because the stainless steel surface doesn't develop the invisible biofilm that colonizes plastic within days, your cat won't detect the "pond smell" that makes them avoid their old fountain or bowl. Most owners report noticeably increased drinking within the first 48 hours.

The pump runs at under 25 dB —quieter than a whisper, quieter than the hum of your refrigerator. Even cats who bolt at the sound of a plastic bag won't be disturbed. Many owners place the fountain in their bedroom and sleep right next to it. If pump noise was why your cat avoided a previous fountain, that problem is gone.

Up to 30 days on a single charge, depending on the flow mode you select

Because Marlene’s Fountain is completely wireless, you can place it wherever your cat actually wants to drink — a quiet hallway, a bedroom shelf, a corner away from food and litter. No cord means placement is based on your cat's comfort, not where your outlet is.

This matters more than most people realize: cats instinctively avoid water placed near food (an evolutionary response to prey-carcass contamination), and being able to separate the two can dramatically increase how much they drink.

Our support team responds to every inquiry within 24 hours — most are answered much sooner.

Whether you have questions about setup, filter timing, ideal placement in your home, or which flow mode works best for your cat, we're here.

We've helped thousands of cat owners optimize their fountain setup for maximum water intake. Just reach out.

Easy — clean in under 10 minutes, we timed it. The streamlined 3-piece design has 70% fewer parts than traditional fountains, so there are far fewer crevices for bacteria to hide.

Both the drinking basin and the water reservoir are 100% dishwasher-safe stainless steel. Rinse, wipe, reassemble — done. A cleaning kit and starter filter are included with every subscription.

4L (132oz) — enough fresh water for nearly 2 weeks for a single cat. The sealed stainless steel design keeps water clean for 7-10 days instead of the 2-3 days typical in plastic fountains, and water level indicators show you when it’s time to refill.

Yes. The 4L capacity and continuous, sensor, or timed flow modes comfortably serve multi-cat households. Many owners with 2-5 cats run a single fountain; for larger households or cats that like to drink in different rooms, the 90-Day plan includes a free 2nd fountain after your 90-day trial.

Most cats switch within the first 48 hours — moving water triggers their natural drinking instinct. If yours doesn’t love it, you’re covered by our Money-Back Guarantee (90 days on the Quarterly Plan, 30 days on the Monthly Plan). We’ll fix it, swap it, or refund it. Whatever makes you happy.

Orders ship free from Pennsylvania and arrive in 3-5 business days within the United States (1 day processing + 2-4 days in transit, based on a 4.2-day average). Actual times may vary during holidays or peak periods.
