What’s in the box?
- 1× KaiShine Wireless Fountain (3.2L, 304 stainless)
- Filters: 1 (One-Time) · 6 (One-Year) · 12 (Two-Year), shipped together
- 1× USB-C charging cable
- 1× Quick-start guide
How do the filters work?
Four stages (non-woven fabric, activated carbon, ion-exchange resin and a foam pre-filter) pull hair, dust and odors out of the water every time it flows, so every sip smells just-poured. Swap the cartridge in ten seconds, about every two months. The One-Year Plan sends refills on their own, and they arrive before you remember.

★★★★★"She heard the water from the other room and came running. Two weeks in, she drinks every time she walks past it — best hundred bucks I've spent on this cat."
Dr. S. Whitfield, DVMVeterinarian
★★★★★"Hydration is the first thing I ask about at every checkup. For cats that ignore their bowl, a quiet moving-water fountain is the single easiest change owners can make."

★★★★★"Our 14-year-old grump took three days to trust it, and now it's his spot. His numbers at the vet were the best they've been in years."

The uncomfortable truth
Your cat’s water bowl is dirtier than you think
Still water grows biofilm, a slimy film of bacteria built from saliva, food bits and dust. In NSF International’s household germ study, pet bowls ranked among the germiest items in the home.
She can smell it long before you can see it, so she quietly drinks less, day after day.
- 4-stage filtration catches hair, dust and debris before every sip
- A fresh, filtered stream every time she comes to drink
- 304 stainless steel is far easier to keep clean than scratched plastic
- 30-Day Picky-Cat Guarantee
- Free US Shipping
- 12-Month Limited Warranty
Her old bowl
KaiShine
Drag to compare
What’s happening in the water she drinks
01
Bacteria & Biofilm Buildup
Still water becomes a breeding ground within hours. That slimy film inside her bowl? A bacteria layer she licks with every single drink.
02
The Drink-Less Spiral
Cats instinctively avoid stagnant water. When it smells off, she doesn’t complain — she simply drinks less, day after day.
03
Stale By Lunch
Her nose is far more sensitive than yours. The bowl you filled at 7 a.m. reads flat, dusty and stale to her by midday.
04
Warm, Flat, Ignored
Warm still water holds less oxygen and tastes worse. KaiShine starts a fresh, filtered stream every time she walks up.

Why hydration matters
Most cats live mildly dehydrated their whole lives. Here is what that quietly costs.
0%
of her natural food is water
Cats evolved eating prey that's about 70% water, so their thirst drive is weak. A still bowl rarely tempts them — many are drawn to moving water instead.
0%
is water in dry kibble
Dry food is only about 10% water, versus about 70% in her natural prey. Cats on kibble have to drink much more, and low intake makes urine more concentrated, a known risk factor for urinary problems.

Develop kidney disease in their lifetime — and low water intake is a known risk factor.

Premium features, built for her everyday hydration
304 stainless steel, 4-stage filtration, a whisper-quiet pump and no cord to chew.
Fresh, moving water, without the daily chore.
4-Stage FiltrationFresh with every sip
A 4-stage filter (non-woven fabric, activated carbon, ion-exchange resin and a foam pre-filter) catches hair, dust and odors. Swap it about every 2 months.
Cordless, 45 Days a ChargePut it where she drinks
A 4200 mAh battery runs up to 45 days in sensor mode. No outlet to find, no cord to chew. Recharges with the included USB-C cable.
Whisper-Quiet PumpShe won’t even notice it
Under 40 dB — about as quiet as a library. Calm enough for nervous cats, and for the bedroom at night.
3.2L TankRefill about once a week
3.2 liters covers most single-cat homes for about a week, and the round window shows the water level at a glance.
Smart Motion SensorFlows when she walks up
Sensor mode starts the stream when she’s within about 3 ft, which saves battery. Want more flow? Timed mode runs short bursts and continuous runs a steady stream (both use more battery).

Kidney & urinary support
"Is she drinking enough?" You'll finally answer yes.
Cats descend from desert hunters — their thirst signal barely works, and still water reads as unsafe. A moving, filtered stream flips both instincts in her favor.
- Cats naturally drink more from flowing water
- Better hydration supports kidney & urinary health
- Designed to make drinking a habit, not an event
Whisker-friendly by design
No whisker fatigue. No plastic aftertaste.
Deep bowls press on a cat's ultra-sensitive whiskers, and scratched plastic harbors the film she can smell before you can see it.
- She laps the falling stream — whiskers touch nothing
- 304 stainless: smooth and easy to rinse clean
- Gentler on chins — helps avoid feline acne
Set it and forget it
Fill it Sunday. She's covered all week.
3.2 liters is a full week of water for most cats — and the porthole window tells you at a glance when it needs a top-up.
- Refill roughly once a week, even less for one cat
- Perfect for weekends away
- Battery lasts up to 45 days per charge
How to use KaiShine
Two minutes out of the box. No app, no account, no plumbing.
1
Fill it
Lift the lid, pour in up to 3.2 liters of water and drop the filter in place.
2
Place it anywhere
There’s no cord, so it goes where she likes to drink, not where the outlet is.
3
She does the rest
The motion sensor starts the stream when she walks up and stops it when she leaves.
Every weekTop up the water
Every ~2 monthsSwap the filter (10 seconds)
Every ~45 daysRecharge with USB-C
Filters arrive on their own with the One-Year Plan, or add the refill subscription to a One-Time order.
What to expect
Many cats investigate the moving stream within the first day.*
WEEK 1Curiosity wins
The sound and sparkle of moving water pulls her in — sniffing turns into first sips.
MONTH 1The habit forms
She visits the stream on her own, several times a day. The faucet begging stops.
MONTH 3+Hydration is routine
Steady daily drinking becomes her normal — the foundation vets ask for at every checkup.
*Individual cats vary — some take a few days to trust something new.

Maya R. Verified Buyer
"I set it down, filled it, and she was drinking before I threw the box away. She trots over every time she hears the little stream start. I didn't know she was this thirsty the whole time."
★★★★★
Linda B. Verified Buyer
"At her last checkup the vet asked what we'd changed — Patches was in the best shape she's been in years. The only thing we changed was this fountain. She drinks all day like it's a hobby."
★★★★★
Sofia G. Verified Buyer
"Noodle used to knock glasses off the counter to get at our water. Now he has his own tiny faucet and acts like he owns a café. Wish we'd bought this the day we got him."

"Excuse the terrible photo, she wouldn't stop moving lol. Biscuit ignored every bowl we owned and now I refill this thing weekly. Weekly!! For a cat that 'never drank.'"

"Got it for one kitten, both of them claimed it. One drinks, the other just watches the porthole like it's TV. Battery's been going almost a month and a half."

Questions cat parents actually ask
Will my cat actually use it?
Moving water triggers an instinct most cats can't resist — it's why she begs at your faucet. Many cats investigate within the first day. If yours holds out for 30 days, we refund everything.
How often do I clean and refill it?
Refill roughly weekly (3.2L tank), rinse the steel when you do, and swap the filter cartridge in ten seconds every ~2 months. Put refills on a subscription and they arrive before you'd remember.
How long does the battery last?
Up to 45 days per charge in sensor mode (4200 mAh), less in timed or continuous mode. Recharge it with the included USB-C cable and any USB phone charger — no dock, no proprietary plug.
Is it really silent?
Under 40 dB — about as quiet as a library — and the stream only runs when she approaches, so nothing hums all night. Cats who feared old grinding fountains sleep next to this one.
Does it help with kidney or urinary problems?
Straight answer: KaiShine encourages drinking, and hydration is the first thing vets point to for urinary and kidney wellness. It's not a medical device and doesn't treat or prevent disease — if your cat has a diagnosed condition, your vet leads.
What if she ignores it?
That's what the 30-Day Picky-Cat Guarantee is for — full refund, no questions. Placement tip: a quiet spot away from food and litter. Wireless makes that finally possible.
When will it arrive?
Orders are handed to the carrier within 2–4 business days, and US delivery typically takes 7–14 business days from the day you order. Shipping is free and tracked. You get a tracking link by email as soon as the carrier scans your package.
What if it stops working?
The fountain has a 12-month limited warranty against manufacturing defects, counted from delivery. Email contactsupport@kaishinepet.com with your order number and a line about what happened, and we’ll sort it out. The warranty doesn’t cover drops, chewing, dishwashers, descaling chemicals or running the pump dry.
How do returns work?
You have 30 days from delivery, and a used fountain is fine. Email contactsupport@kaishinepet.com with your order number. We reply within one business day with instructions and, where a return is needed, a prepaid label. Once the carrier scans it, we refund you in full within 2 business days.
Is it enough for two cats?
Yes. With two cats, plan to top up the 3.2-liter tank about twice a week. The Two-Year Plan’s 12 filters are the easy choice for two-cat homes.
Give her the water her instincts ask for.
A stream she trusts, steel that rinses clean, refills that show up on their own — for less than a single vet visit.
