Plenish™ The Filterless Self-Refill Fountain
How It Works
How It Works
Plenish™ uses a patented dual-tank system that physically separates clean and dirty water. When your pet drinks, the used water goes into a separate waste tank and is never recycled. Since the water isn't recirculated, there's no bacterial buildup that needs filtering.
You simply dump the waste tank and refill with fresh water - no filters required, saving you $100+ yearly.

Why Traditional Fountains Make Cats Dehydrated
Traditional fountains recirculate the same water over and over. That means saliva, food particles, and bacteria cycle through 24/7, Even with filers, you're just trying to clean contaminated water that shouldn't be recycled in the first place.
To them "filtered" water that's been recycled for days smells absolutely disgusting, so they walk away and become dehydrated.
When cats avoid stale water, crystals form, stones devolop, and urinary blockages happen - costing $2,000+ in emergency vet bills
The filter industry makes $2 billion a year from pet parents stuck in this cycle. Buy. Hope. Fail. Reapeat.
What if one fountain could last all year AND actually make your cat drink more
Fresh Start Sale
For a limited time, get 50% off your Plenish fountain. That means fresh, filterless water for your pet — no more slimy bowls, no more filter runs, no more vet bills from dehydration. All for half the price. Don't wait: this deal won't last, and your pet's health will thank you.
Why Your Pet Deserves Plenish
Your pet can't tell you when they're thirsty. They can't tell you the water tastes stale, or that the slimy buildup in their bowl is making them drink less. They just quietly become dehydrated — and you don't find out until a vet visit that costs thousands.
Plenish was built to fix that. Fresh water, automatically, every few hours. No filters to buy. No biofilm to scrub. No guessing. Just clean water, every single time they walk up to drink.
Because they deserve better than recycled water.

Testimonials
-
My husband admitted it was a good buy
"My husband thought I was crazy spending money on a water fountain for a cat. He admitted last week it was a good buy. That's all I'll say."
-
Just sits there doing its thing
"Three cats, one fountain, zero complaints. The tank lasts almost a full week before I need to refill. It just sits there doing its thing."
-
Her vet is happy
"Got this for my older cat who has kidney issues. Her vet said increased water intake is the most important thing right now. She drinks from it multiple times a day."
Trustpilot reviews
Excellent 4.8 / 5
-
Rinse and go
"Cleaning it takes no time at all. My old fountain had parts I had to scrub with a tiny brush every few days. This is just rinse and go."
-
My anxious cat took to it straight away
"It's quiet which was my main concern. My cat is anxious and I was worried she'd be scared of it. She sniffed it for like ten minutes then started drinking. No issues at all."
-
Wish I'd found it sooner
"My vet mentioned my cat wasn't drinking enough water at his last checkup. Got this a month ago and he's at it constantly now. Wish I'd found it sooner."
-
Don't have to buy filters anymore
"The fact that I don't have to buy filters anymore is genuinely life changing. I didn't realise how annoying that was until I stopped doing it."
-
She went straight to it
"Honestly bought this kind of skeptically but my cat proved me wrong within the first hour. She went straight to it and hasn't touched her old bowl since."
-
Really good, minor gripe
"Really happy with it overall. My cat drinks so much more water now and not buying filters is a win. Only docking one star because the tank goes faster than I expected with two cats. Still recommend it."
